Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday 31 October 2024.
Last weekendâs CQWW SSB contest showed just how good autumnal HF conditions can be. Many contestants worked more than 100 countries or DX entities on each and every HF band.
With a solar flux index of 238 on Saturday and 246 on Sunday, plus low Kp indices all weekend, it was about as good as it could get. There were two three-hour periods where the Kp index hit four and 4.33, but it was otherwise in the ones and twos.
An X-class solar flare occurred on Saturday the 26th at around 07:15 hrs UTC, but this had little effect and the MUF over a 3,000km path was back above 28MHz quite quickly.
The rest of the week saw numerous M-class and C-class solar flares occur and a Kp index that did get up to four at times, but once again the MUF remained above 28MHz during daylight for most of the time.
Interestingly, there have been times when the critical frequency over the UK has hit 14MHz, making 20m almost a local chat band via Near Vertical Incidence Sky Wave or NVIS communications! These openings may be short-lived so make the most of them should they occur.
Nighttime critical frequencies have generally been around 4.5-6MHz, meaning a MUF over a 3,000km path over 14MHz in the first half of the night and around 10-12MHz in the second half.
The solar proton flux has been above the 10MeV warning threshold but is now falling as of Thursday 31st. This may improve signals that pass through the polar regions, such as the UK to the far west of Canada and Alaska, and the UK to Japan.
Next week NOAA predicts that the SFI will start at around 240, but perhaps fall to around 195-200 as the week progresses. ESA predicts that the solar wind speed could increase around November 4th and could cause disruption.
As always, we are at the mercy of solar flares and CMEs, which could disrupt HF propagation, so we recommend keeping an eye on solarham.com for daily updates.
And now the VHF and up propagation news from G3YLA and G4BAO
The Autumn Equinox period continued to bring F2-layer propagation to 50MHz with almost daily morning openings to VK and JA and afternoon openings to the Americas for some.
Stations in the far South and West of the island were favoured. Side scatter in the Indian Ocean brought the JAs on a 90-degree beam heading, an effect noted at previous sunspot maxima.
The autumn is typically a time for quiet settled weather, a season of mist, and this is where we are going for the period through to the end of next week. It's worth a couple of reminders of how it all works since, although it's likely to be pretty much the same âbig pictureâ of dominant high pressure, there will be subtle differences.
Firstly, there are two types of high pressure; one that builds in warm air and the other in cold air. The warm air version is the current offering, and this means quite cloudy conditions at times with moist air below the temperature inversion and very dry air above the inversion.
Second, the quality of the ducting is determined by the change of the refractive index across the inversion and a large part of the refractive index change comes from a contrast of moisture, so signs of cloud and/or fog moisture are good omens for a lift. We may swap over to a cold air high later next week, which could lessen the Tropo quality.
Meteor scatter prospects are on hold pending the Leonids meteor shower, which peaks mid-November. A dominant high pressure means that rain scatter is not likely to be a big player for the GHz bands next week.
There is a possible heads-up for aurora since the solar conditions still offer chances for the Kp index to rise â anything over Kp=4 is worth a longer look â and donât forget that âwateryâ signals on the lower HF bands such as 40m and 80m are also a good sign.
For EME operators, Moon declination reaches a minimum (that is, maximum negative declination) next Tuesday when the Moon only reaches nine degrees peak elevation and is only above the horizon for six hours between 1200 and 1800hrs. Path losses, on the other hand, are falling all week.
144MHz sky noise is moderate to high, peaking at more than 3,000 Kelvin on Tuesday the 5th before dropping back to moderate levels.
And thatâs all from the propagation team this week.

If you are thinking of taking an amateur radio exam before Christmas, there are two important dates you need to be aware of. The last date you can take an exam at a club, whether online or on paper, is Friday the 13th of December. If you want to take an exam online at home, the last date you can do that is Friday the 20th of December. The RSGB Exams Team will, where possible, post-out exam results before HQ shuts over Christmas and New Year. Exams will resume on Monday the 6th of January 2025 and the booking system will be available over the festive season so you can book exams for January onwards. You can book online on the RSGB website at rsgb.org/exampay
On Friday the 18th of October the RSGB, Mill Hill School and a team of radio amateurs in New Zealand took part in a special celebration to mark the centenary of the first successful two-way trans-global communication between radio amateurs in the UK and New Zealand. The original contact between Frank Bell, 4AA in New Zealand and Cecil Goyder, 2SZ in Mill Hill School in North London was re-enacted at the school on a wavelength as close as possible to the original. Members of Goyderâs family watched the re-enactment and chatted to pupils. As part of wider celebrations for the day, the school put on activities including a build-a-radio workshop. Students at the school showed significant interest in amateur radio, with several students signing up to be part of a new radio club that will be set up by the schoolâs physics teacher. The overall event was led by RSGB Life Vice-President Don Beattie, G3BJ who said that he was delighted by the success of the event and that it had allowed pupils to learn how ground-breaking that first radio contact was with New Zealand. Call sign G2SZ was operational for four days surrounding the centenary, during which operators achieved approximately 1,250 contacts. To find out more about this unique celebration go to www.gb2nz.com and search for âGB2NZ re-enactmentâ on the RSGB website.
The Memorial Day QSO Party is an activity providing participants with an opportunity to honour amateur radio operators who are now Silent Key. The event is being sponsored and managed by the First Class CW Operatorsâ Club and is open to all licensed amateurs. The event begins at 0900UTC on the 1st of November 2024 and ends at 0859UTC on the 2nd of November. More information is available at g4foc.org or by emailing [email protected] or [email protected]
Ofcom has notified stakeholders that the next release of its licensing service will be delayed due to issues that have arisen during software development. According to the Ofcom website, the delays have impacted Phases 2 and 3 of the planned changes to the amateur radio licensing framework.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 24th of October 2024
Last weekâs solar conditions couldnât have been much better. We had a week of high solar flux indices, relatively calm geomagnetic conditions and, other than an X-class solar flare, not much else to report.
The solar flare originated from active region 3869 and reached a strong X3.3 in the early hours of October 24th. This event was associated with a coronal mass ejection, or CME, based on solar dimming following the event, but because the flare location was located off the east limb, it was directed mostly away from Earth.
Once again, all the sunspots are in the southern hemisphere, but activity appears to be growing. This could spell trouble over the next week.
This weekend, the 26th and 27th, the CQ Worldwide SSB contest is taking place and conditions should be excellent, with a combination of high solar flux and autumnal HF conditions.
Maximum usable frequencies, or MUFs, are generally higher than 28MHz from dawn until dusk. Nighttime MUFs over 3,000km are still just above 14MHz, although you might get better results by dropping down to 10MHz if the 20m band doesnât work for you.
Next week, NOAA predicts that the solar flux index may rise again, perhaps hitting 185 as we enter November. However, this current bunch of sunspots, which are rotating to be Earth-directed next week, appear more active and we could see more solar flares and CMEs, which could throw a spanner in the works.
A solar flare could impact the ionosphere by increasing D-layer absorption, for up to an hour or so, and possibly launch a coronal mass ejection.
If a CME hits the Earth, expect the MUF to plummet, at least for a day or two until the ionosphere recovers.
And now the VHF and up propagation news from G3YLA and G4BAO
The Autumn Equinox period brought some amazing ionospheric propagation to 50MHz on Thursday last week with stations in the UK working morning paths to VK, JA, DS and XV among others.
Typically for 50MHz DX, the skip zones were sharp and moved rapidly. Stations even a few kilometres apart experienced very different signals and paths. Those with a low noise floor had a huge advantage as signals were generally weak in the UK and only good for FT8. However, some reports of a VK station at +5 bucked this trend.
Next week will offer some reasonable Tropo conditions, although not without some occasional interruptions from weak frontal systems, especially in the far southwest and the far northwest of Britain. Itâs not clear if these represent good rain scatter options, but they are more likely to temporarily curtail any Tropo for a while.
The solar conditions continue to feed the occasional aurora alert our way, so itâs always good to monitor the Kp index for signs of it increasing above 4. It wonât always go on to produce a radio aurora, but it's worth keeping an eye on things.
The meteor scatter prospects continue to be elevated by the decline of the Orionids, which peaked on Tuesday the 22nd, and the Taurids, which are a very low-rate shower, but technically cover a broad period into December. The Leonids are the next major shower, but that doesnât peak until mid-November.
Lastly, looking at the out-of-season Sporadic-E prospects, there are always days with minor enhancements of the critical frequency of the Sporadic-E layer, as shown on the propquest.co.uk graphs. Certainly, there are stronger jet streams available in the autumn and winter, but other elements of Sporadic-E are not so favourable. Itâs usually a very marginal outcome at best, but good enough for the 10 or 6m bands and mostly for digital modes such as FT8.
It could well be that trans-equatorial propagation, or TEP, is a more fruitful venture.
For EME operators, Moon declination is positive, but falling, going negative on Tuesday the 29th. Path losses are rising, reaching a maximum at apogee on the morning of Wednesday the 30th. 144MHz sky noise is low until Friday the 1st of November when the Sun and Moon are close in the sky.
And thatâs all from the propagation team this week.

The news headlines:
The RSGB welcomes your feedback on its 2024 ConventionToday is the last chance to get involved with JOTA 2024The RSGB is looking for Youth ChampionsThe RSGBâs 2024 Convention took place last weekend and brought together hundreds in person, as well as many more from across the globe who watched via the livestream. The Society is already receiving an overwhelming amount of positive feedback, but if you did attend the Convention and havenât yet completed the feedback form, please go to rsgb.org/feedback and share your thoughts. If you watched the livestream the Society would also love to hear your feedback. Please visit rsgb.org/livestream-feedback and let the team know what you think of the online event. The feedback forms will be closed at the end of October. The live streams for both days will remain available for everyone to watch, so if youâd like to catch up on the selection of presentations that were aired, go to the RSGB website and search for âConvention 2024 Livestreamâ. As well as talks from the weekend, youâll find exclusive special interviews and pre-recorded videos.
Today, the 20th, is the last day of Jamboree on the Air, also known as JOTA. The event promotes friendship and global citizenship and is a brilliant celebration of amateur radio among the Scout Association. The Society has compiled a list of Scouting groups that are involved with the annual event and has shared it on its website. The list is available by going to rsgb.org/jota and choosing the âJOTA Stations on the Airâ link on the right hand side of the page. The RSGB would love to see your photos of Scouts getting involved with JOTA, so tag @theRSGB and also use #JOTAJOTI to be involved in the conversation on social media. If youâre not involved with a JOTA station do listen out and encourage the young operators on the air. There will be a report in RadCom so please send details and photos from your event to [email protected] by the 15th of November.
Following the recent appointment of two Youth Champions for schools and universities, the RSGB is keen to expand the team. The Society is looking for a Youth Champion for scouts, guides and cadets, and another to lead activities and create resources to support young people once they have gained their Foundation licence, motivating them to try new things within amateur radio. The four Youth Champions will work closely as a team, as well as with the RSGB Board Liaison, Ben Lloyd, GW4BML and the RSGB Outreach Team. Together, the Youth Champions will also create a youth team and run a net or sked to involve all youngsters. Do you have what it takes to engage with young people and support them on their amateur radio journey? Another part of each Youth Championâs role is to give input and support for current activities, such as promoting and participating in Youngsters on the Air Month each December. If you are proactive, experienced at managing your own time efficiently, a good leader who can build relationships and mentor young people, and you are passionate about growing the number of young people involved in amateur radio, then one of these roles could be for you! Take a look at the youth activities on the RSGB website at rsgb.org/youth and see some of the great things that are happening already. If youâre interested in being part of the team, contact Youth Board Liaison Ben Lloyd, GW4BML via [email protected]

As part of the celebrations to mark the centenary of the worldâs first trans-global two-way radio communication, special callsign GB2ZL has been active at times from the UK. This is in addition to the main UK activity from GB2NZ, G2SZ and others. On Tuesday the 15th of October, the GB2ZL station, operated by Chris GM3WOJ from near Inverness, made a remarkable QSO with the ZL4AA team located just North of Dunedin. The ZL4AA station was operated by Dave ZL4DK, Mike ZL4OL and Stephen ZL4BN. This QSO, on the 40m band, long path at 0721UTC, was made using CW. 559 reports were exchanged each way and the operators at both ends were thrilled to make the contact. At each end of the QSO was an 80-year-old all-valve military transceiver from New Zealand, the iconic ZC1. These radios date from 1944, just 20 years after the first UK to New Zealand QSO. For more information about the station and the ZC1 transceiver visit the GB2ZL page at QRZ.com

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 17th of October 2024
The past week has been characterised by a low geomagnetic Kp index and excellent conditions on HF, including the 10m band. With a solar flux index between 168 and 195, and a Kp index that never rose above 4, conditions have been better than the previous week, which suffered from the bad effects of solar flares and coronal mass ejections.
This came as NASA, NOAA and the International Solar Cycle Prediction Panel announced that the Sun has reached its solar maximum period, which should continue for the next year.
The announcement was not unexpected, and the exact period of maximum activity wonât be known for some time. But it was a wake-up call for radio amateurs to get on the bands and make the most of the conditions!
NOAA anticipates additional solar and geomagnetic storms during the current solar maximum period and during the declining phase of the solar cycle.
The solar flux index fell from its 200-plus highs to be in the 160 to 195 range last week. But this was still more than enough to keep the ionosphere running. Maximum usable frequencies over a 3,000km path have been consistently over 28MHz during daylight, falling to around 11MHz overnight.
Next week, the Space Weather Prediction Centre thinks the solar flux index will rise into the 200s again, but we may also get some geomagnetic disturbances, namely on the 22nd and 23rd when the Kp index might rise to around 4.
Meanwhile, October can be one of the best months for HF propagation with good 10m band openings to Australasia in the morning and North and South America in the afternoon.
And now the VHF and up propagation news from G3YLA and G4BAO
The current unsettled spell of weather seems likely to continue into next week and is not atypical at this time of year. We should expect a more changeable pattern around the autumn as the main polar front jet stream migrates south across the UK into its winter state over the Mediterranean.
That said, there may well be some brief interludes when the extended region of high pressure across Europe influences conditions over the British Isles, more specifically the southeastern corner.
This is shown by some models around midweek for potential Tropo from southeastern England into the continent or across the North Sea to northern Europe and southern Scandinavia.
The obvious mode to result from this unsettled weather will be rain scatter and it is probable that the GHz bands will enjoy this period of weather.
Meteor scatter in October has a few showers to maintain interest. The Orionids and the Taurids are both active during the coming week. In fact, the Orionids, associated with the comet Halley, peak on Monday and Tuesday.
Just a final note about Sporadic-E, which is âout of seasonâ. Remember that there are no âzero Sporadic-E monthsâ and recent indications have tended to show the response of raised critical frequencies of the Sporadic-E layer occurring around the middle of the day on the propquest.co.uk NVIS graphs.
You may also see peaks earlier in the day around dawn, which is the peak time for meteor input. Beware, it is easy to get hooked on out-of-season Sporadic-E hunting!
For EME operators, Moon declination is positive and rising. Path losses are rising again after the perigee on Thursday the 17th. So, we have increasing peak Moon elevations and longer Moon windows until Tuesday the 22nd. 144MHz sky noise is low to moderate for the rest of the week.
And thatâs all from the propagation team this week.

GB2RS News
Sunday the 13th of October
The news headlines:
The RSGB 2024 Convention is taking place this weekendTwo new volunteer Youth Champions have been appointed by the RSGBCelebrations are underway to mark the first trans-global two-way radio communicationThe RSGB Convention has been in full swing this weekend. If you havenât been able to attend, the RSGB has provided a packed live stream on each day and those live streams are available for anyone to view. Full of presentations, interviews and videos to inspire you, this is another way to enjoy your Convention, in your way. Either go directly to the RSGB YouTube channel or head over to rsgb.org/livestream to see the programme of presentations and the links to the livestreams.
The RSGB is delighted to announce the appointment of two new volunteer Youth Champion roles. Chris Aitken, MM0WIC will be the RSGBâs School Youth Champion and Rhys Williams, M0WGY/AJ6XD will be the University Youth Champion. Chris is a Computing Science teacher at Wick High School, Caithness. Since 2023, Chris has been running the Wick High School Radio Club, GM0WHS, providing students with a wide range of experiences in amateur radio. He has four students who have passed their Foundation licence exam and are now taking on leadership roles within the club and assisting the latest cohort in their studies. He is also a member of the RSGB Outreach Team. You can contact Chris via [email protected] Rhys represented the RSGB at the Youngsters on the Air Camp in Prague this year. He sent back daily reports on his activities which you can still see on the website under the summer camps tab at rsgb.org/yota He is starting a PhD in Aerospace Engineering at the University of Oxford and is keen to help the RSGB support the growth of amateur radio in universities across the UK. You can contact Rhys via [email protected] Ben Lloyd, GW4BML is the Board Liaison for youth activities. He said that he welcomes Chris and Rhys to their new youth volunteer roles and looks forward to working closely with them in the future to attract and grow RSGB youth membership. He explained that the three of them have already had some positive conversations and shared some good ideas, which they will be putting into place over the coming months.
This week marks the centenary of the worldâs very first trans-global two-way radio communication. On the 18th of October 1924 Frank Bell, 4AA, from New Zealand, and Cecil Goyder, 2SZ, from North London, changed how we communicate forever by making contact on amateur bands. To commemorate this historic contact, special callsigns will be active, and awards and QSL cards will be available for those who make contact with these special stations. GB2NZ and ZM100DX have already been active since the start of the month. Starting tomorrow, until the 20th of October, calls reflecting Goyderâs callsign, G2SZ, and Bellâs, ZL4AA, will be active. This will include activity here in the UK from Mill Hill School in North London which is the original location from which Goyder made his contact. On Friday the 18th of October, radio amateurs will also be recreating and re-enacting the first contact between Goyder and Bell. It is hoped that the QSO will be made on a wavelength close to that used in 1924. To find out more about this unique celebration go to gb2nz.com
YOTA Month is just around the corner, and the RSGB is looking for volunteers to host the GB24YOTA callsign throughout the month of December. As in previous years, schools, clubs, guide and scout groups and also individuals are invited to host young radio amateurs whilst they operate with the callsign. Each day during the month has been split into a number of operating slots that you can book. In recent years, this system has allowed many more youngsters to get on the radio throughout the month. You can see the operating calendar by visiting QRZ.com and searching for GB24YOTA. Operators should be below the age of 26. Those who do not hold a Full amateur radio licence should be supervised by an appropriate Full licensee whilst operating. The RSGB is pleased that previous activators have already reached out to book their operating slots but there are still many more up for grabs! To book an operating slot or for more information about YOTA Month, please email Jamie, M0SDV at [email protected]
During last monthâs Hamfest in Newark, the ICQ Podcast team spoke with RSGB President John McCullagh GI4BWM, RSGB Board Chair Stewart Bryant G3YSX and RSGB General Manager Steve Thomas M1ACB. Listen to Episode 440 of the podcast series to hear them discuss some of the many events that the Society is currently involved with.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Wednesday the 9th of October 2024
What a difference a week makes when it comes to HF propagation!
This last week has been characterised by solar flares, coronal mass ejections, or CMEs for short, and an elevated Kp index. Put together, this has resulted in dire conditions on HF, reminiscent of a solar minimum.
A visible aurora was seen from the UK once again after the Kp index hit 7.33 on the 8th of October.
Numerous CMEs have hit the Earth and the solar proton flux has risen, resulting in a moderate S2 radiation storm as particles blasted away from the flare site.
This means poor trans-polar paths until the solar wind abates and the storm settles.
Maximum usable frequencies have been badly affected and struggled to get much past 14MHz over a 3,000km path on the 8th of October. Geomagnetic storms were also forecast for Thursday the 10th and Friday the 11th.
Thatâs a shame as, before the CMEs hit, HF had been humming with a lot of DX on the 28MHz band and many five-watt beacons romping in from the USA.
Next week, NOAA predicts that the solar flux index may drop back into the 170s, but itâs anyoneâs guess as to how geomagnetic conditions will pan out.
We have had three X-class solar flares over the past week and on Wednesday the 9th the probability of another X-class solar flare was estimated at 30% and an M-class event at 75%. So, it may be a case of âbatten down the hatchesâ on HF until the storm conditions pass.
This is not uncommon at this point in the solar cycle and unsettled conditions are likely to continue as we move along the downward portion towards the solar minimum.
And now the VHF and up propagation news from G3YLA and G4BAO
The current spell of unsettled weather is probably going to flip into high-pressure mode a couple of times during the coming week. The first of these will be today, the 13th, and through the first half of next week.
However, by Wednesday the next change back to low pressure should be with us, closely followed by another attempt to build high pressure later in the week.
This offers something for everyone with prospects for rain scatter on the GHz bands and the possibility of Tropo.
The prospects for meteor scatter are also good with October offering several useful meteor showers.
While 50 and 70MHz are the best for the mode, look at 144.360MHz in MSK144 digimode. Or, if itâs a shower peak, 144.200MHz, the SSB meteor scatter calling channel, to see whatâs around.
The solar conditions continue to behave like a solar maximum and, with several recent powerful flares and CMEs to stir things up, we should continue to check the bands for signs of aurora.
The recent RSGB CW 80m Autumn Series Contest on Monday the 7th of October was about as auroral as it gets with a strong flutter on signals and a challenging hour and a half for participants â so not just an effect for VHF.
The RSGB 1.3GHz UK Activity Contest coming up next week on Tuesday the 15th may be on the changeover from high pressure to low. Tropo might be limited to eastern areas for paths across the North Sea to northern Europe.
For EME operators, Moon declination is still negative but will rise to positive by Tuesday night. Path losses are falling towards a minimum at perigee on Thursday the 17th.
So, we have increasing peak Moon elevations and longer Moon windows with the lowest loss for the coming week. 144MHz sky noise is low for the rest of the week.
And thatâs all from the propagation team this week.

There is still just time to buy your tickets in advance, but hurry as advance sales for attending the Convention or the dinners closes tomorrow, Monday the 7th of October. You will be able to buy a Convention ticket on the door but not at the discounted rate that is available now. At the event, there will be a varied programme of presentations regardless of your amateur radio interests or experience, as well as practical workshops and Morse competency tests. Youâll also find a room full of special interest groups to chat to who could inspire you to try something new! If youâre unable to travel to the Convention, a small number of presentations will be live-streamed and will be available on the RSGB YouTube channel without the need to pre-register. The RSGB has released two âConvention Chatâ videos recently and will be releasing two more over the coming week, so find out what others think of the Convention and see who you might bump into in the bar! For full programme details and speaker information and to book in advance, go to the RSGB Convention web pages at rsgb.org/convention
Did you take part in National Coding Week this year? The RSGB had nine activities to inspire you to take part, including two new worksheets developed by the Societyâs Outreach Team. Whether you took part by yourself, at a club night, or with friends and family, the RSGB would love to hear from you. To be included in the RadCom December feature on National Coding Week please send a summary of your activity, along with any photos, to [email protected] by the 17th of October.

The next RSGB Tonight@8 live webinar is tomorrow, Monday the 7th of October. Ian White, GM3SEK will present âAircraft Scatter, the Hitch-Hikers Guideâ. Aircraft scatter is about bouncing VHF and UHF radio signals off high-flying aircraft â effectively âhitching a rideâ with someone elseâs plane to extend your everyday working range up to 800km. It may sound rather technical, but with some explanations from Ian, aircraft scatter might soon feel very easy. During the talk, Ian will consider how aircraft scatter works, and if itâs so useful, why havenât we heard more about it? Join the webinar live at 8 pm on the RSGB YouTube channel or special BATC channel. Find out more about this and other webinars on the RSGB website via rsgb.org/webinars
grid.radio is a web application born out of the frustration that Rose, 2E0RXO and many others experienced during spontaneous, often unplanned, Parks on the Air activations. During busy moments, someone would inevitably ask for a Worked All Britain square or another reference that she wasnât prepared for. There wasnât a single, simple resource to quickly gather this information with a fast-loading, modern interface. Many websites would spend more time loading advertisements than displaying the necessary information, delaying communication and increasing the pending pile-up. After several months of facing the same issue and finding herself still unprepared, Rose, a Computer Science graduate, decided to solve the problem with code. She created a fast, free web app that can be installed on the home screen of any phone or tablet or accessed on a desktop computer for pre-activation planning. You can also share links so others can easily find out where you are operating from. Once installed, the app will even work without a data connection. Development is ongoing, with feedback from all amateur radio operators welcomed via the contact details on Roseâs QRZ.com page. To learn more about this useful web app visit grid.radio

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 3rd of October 2024
In the first week of October, the 10m band began to show what it is capable of. With a solar flux index in the high 200s and calm geomagnetic conditions, DX was plentiful.
Nick, VK9DX on Norfolk Island was audible on SSB all morning on Wednesday the 2nd and only wanted to work G stations. This made him popular in the UK, but less so in other countries!
Vlad, 5H1WX, on Mafia Island, Tanzania, was another strong signal on the morning of the third. Meanwhile, the 3D2V Rotuma Island DXpedition near Fiji on the 10m band using FT4 was another catch for many people.
The Kp index managed to remain low for the first half of the week, but there were warnings that a coronal mass ejection, which was attributed to the X7.1 solar flare on the 1st of October, might upset things later in the week.
With a good spread of sunspots, mainly in the Sunâs southern hemisphere, there could be more flares over the coming days.
Scott Mcintosh, the solar physicist who predicted a busier than average Cycle 25, has now questioned whether we are past solar maximum. The fact that there are now fewer sunspots in the Northern Hemisphere suggests that we may be past the peak, but only time will tell.
Meanwhile, NOAA predicts the solar flux index may decline towards the 200 mark next week. The Kp index is predicted to go to 4 this weekend. With four of the ten active sunspot groups now classed as growing, we may expect further solar activity and geomagnetic disturbances over the next seven days.
And now the VHF and up propagation news from G3YLA and G4BAO
The brief period of high pressure that arrived towards the end of the previous week is currently being nudged away to the east into Europe.
The coming week is dominated by very unsettled conditions with a succession of deep lows near or crossing the country and thereâs even one that contains the remnants of an old hurricane.
The result is that next week will provide copious amounts of wet and windy weather, so no Tropo for us, but there may be several areas of heavy rain for a try at rain scatter on the GHz bands.
We hope you have all checked out your antennas after last weekâs reminder since the winds may be quite testing for some areas.
The solar conditions have been stirred up recently by several flares so, as usual, keep an autumn watch out for auroras.
Lastly, there are plenty of meteor scatter opportunities aside from any random meteor activity. Try investigating one of the many meteor websites to see the full list of options.
For EME operators, Moon declination is at its minimum on Wednesday. So, it is a good week for checking out systems before the Sun also gets too low in the sky to make sensible Sun noise measurements over the winter. Path losses are still high but starting to fall.
If youâre fortunate to have a clear low horizon youâll make some contacts, but with peak Moon elevation only eight degrees on Wednesday, youâll be lucky! 144MHz sky noise in general is high to moderate for the rest of the week.
And thatâs all from the propagation team this week.

The news headlines:
There is still time to book tickets for the RSGB 2024 ConventionThe RSGB is helping to promote JOTA activities in OctoberThe RSGB has responded to a recent Ofcom Consultation concerning the 2.3GHz bandWith just two weeks until the RSGB Convention, this yearâs event is the place to go if you are interested in anything and everything to do with amateur radio. There will be a host of expert speakers presenting on topics ranging from Sporadic-E and how to use AI to write amateur radio applications, to panel debates on amateur radio modes and presentations on inspiring the next generation of radio amateurs. The presentation summaries and speaker biographies are now available on the RSGB speaker page. AMSAT-UK has started to release news of its presentations too and you can see those on the RSGBâs Convention programme. There really is something for everyone. If you havenât already bought your ticket, be sure to secure it by Monday the 7th of October when the online booking process will close. Buying tickets before the event will save you up to ÂŁ5 off the usual 'on the day' ticket prices. Due to demand, the RSGB has also arranged an extra introduction to microcontroller programming workshop that will take place on the Sunday morning. There are still some tickets available for Saturdayâs Gala Dinner too. To book your tickets for any part of the weekend or to find out more about the programme go to rsgb.org/convention
Jamboree on the Air, also known as JOTA, is taking place between the 18th and 20th of October. The event promotes friendship and global citizenship and is a brilliant celebration of amateur radio among the groups within the Scout Association. Some groups have already shared details of activities that will be taking place over the weekend and the RSGB plans to compile and share a list of these on its comms channels. If you are part of a Scouting group and are planning to get involved with JOTA then please get in touch via [email protected] with a summary of your station name, callsign and any other relevant information.
The RSGB has responded to a recent Ofcom Consultation which would see new users sharing spectrum within the 2.3GHz amateur band. Whilst the new devices may be limited to indoor use, the RSGB has taken the opportunity to highlight concerns regarding the weak signal 2320MHz segment. In addition, the RSGB has also indicated its wish to review the current restrictions that apply to this band that date back to 2013, when it was subject to Public Sector Spectrum Release. The response and background information can be found in the Spectrum Forum web pages at rsgb.org/spectrum-forum
The October edition of RadCom includes an article about the very first two-way radio communication between the UK and New Zealand, something that Sir Edward Appleton, radio physicist and Nobel laureate, later described as âprobably the most dramatic moment in the history of the development of the short waves.â The contact was between two radio amateurs, one in Mill Hill School, London and the other on a sheep farm in New Zealand. Centenary celebrations will be taking place in New Zealand and at Mill Hill School, and special event callsigns will be active from today until late October. GB2NZ and ZM100DX will be active each day during that period and, for the week of the centenary, the near-actual callsigns used in 1924, G2SZ and ZL4AA, will be active from the 14th to the 20th of October. A commemorative certificate will be available for those who make contacts with the event stations. For more information on the Goyder-Bell award, and to find out more about the centenary celebrations, go to gb2nz.com
Lots of amateur radio stations are on the air this weekend for the Railways on the Air event.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Wednesday the 25th of September 2024
Solar activity is back to moderate levels with an M3.7 solar flare detected on the 22nd of September. Newly assigned AR 3835 in the southeast quadrant is the main source and the event looks to have thrown a stream of plasma into space.
The latest model suggested a possible passage near our planet by the 25th and it looks like the prediction was correct. The Space Weather Prediction Centre issued a G1 geomagnetic storm watch and visible aurora may be likely at very high latitudes. Expect maximum useable frequencies, or MUFs for short, to decline if the Kp index is above 4 or 5.
Other than a large number of C-class solar flares in the past five days, this was the biggest eruptive event to occur.
The solar flux index had declined to 172 on Wednesday the 25th but is unlikely to decrease much further. Note that nearly all the sunspots are in the Sunâs southern hemisphere at the moment.
Meanwhile, daytime MUFs over a 3,000km path are now consistently over 28MHz under quiet geomagnetic conditions. This is good news for fans of the 10m band. Night time MUFs over 3,000km are around 14 to 16MHz, so it looks like we may soon lose the 24-hour DX openings on the 20m band, which are prevalent in the summer months.
Increasing solar proton flux at the moment means paths over the Arctic Circle may be compromised.
Daytime critical frequencies remain over 8MHz and often reach nearly 11MHz, so NVIS communications around the UK on the 40m band remain commonplace but may disappear later in the evening.
NOAA predicts that the solar flux index will increase next week but may not reach the 200s. Keep an eye on solarham.com for daily updates.
And now the VHF and up propagation news from G3YLA and G4BAO
The present run of unsettled weather has become firmly established and, although many parts of the country have not seen the torrential rain and flooding of last week, there will be some rain at times in most parts of the country during the first week of October.
There are a couple of brief periods in the models when a weak ridge of high pressure is due to cross southern areas, but these are not seen as great for Tropo.
The week beginning Monday the 30th of September sees at least two major lows pass close to northern Britain. One occurs as this weekend draws to a close and there may be another one later in the week. These types of changeable patterns are notorious for problems with detailed predictions beyond a few days, although the general weather type is well forecast.
Just a reminder that strong wind events at the end of a long summer can be a big shock to antennas, so now is a very good time to check that all is well in the guying department.
Having discounted Tropo as an option, the obvious choice will be rain scatter on the GHz bands, but some of these events may produce very fast-moving echo sources. So, it could be quite a challenge although last week saw plenty of good rain scatter conditions.
Meteor scatter is again largely dependent upon random meteors with just a couple of lesser showers, the Kappa Leonids and Sextantids, which see out the end of September.
The auroral situation continues to provide some excitement, and the autumn months are a good time of the year for such things.
For EME operators, Moon declination is still positive until Tuesday evening, so Moon visibility windows are shortening. Path losses are high with apogee next Wednesday the 2nd of October. Thursday the 3rd sees near-eclipse conditions when the Sun and Moon are close in the sky meaning high noise with wider beam width antennas. 144MHz sky noise is, in general, low for the rest of the week.
And thatâs all from the propagation team this week

The news headlines:
The RSGB Convention is just three weeks awayThe RSGB has announced that routine bookings for paper exams will ceaseTake advantage of group activity opportunities at the RSGB National Radio CentreThe RSGB Convention is just three weeks away and there is a fantastic programme planned. Whatever your amateur radio interests or experience there will be something for you. In addition to the presentations, you could take part in a workshop to learn more about microcontroller programming â spaces are limited so make sure you book soon if you want to be part of that event. There will also be an EMF and EMC Clinic, contest forums and a chance to find out more about a wide range of amateur radio special interest groups. The social side of the Convention is important too, whether youâre catching up with friends over coffee or enjoying the Gala Dinner on Saturday evening. Day or weekend tickets for the Convention are still cheaper if you buy in advance rather than on the door, and the deadline for advance tickets is Monday the 7th of October. To find out more about the programme, the speakers and to book your tickets, go to the RSGB Convention web pages at rsgb.org/convention
The RSGB has announced that from the 29th of November it will stop taking routine bookings for paper exams. Currently 97% of amateur radio licence examinations are taken online using the TestReach platform, either at home under remote supervision or in a club setting. Following the implementation of Syllabus v1.6 on the 1st of September 2024, the new examination question bank will only be maintained online. Generating paper exams will involve significant additional work for the RSGB Examinations Department, with the associated costs. You will be able to apply for a paper exam on the grounds of special educational needs in the same way that you can currently request special requirements such as extra time or a reader. To do that you need to email the Exams Department via [email protected] To read the full details of the changes, including the three important dates you need to know, please go to the RSGB website at rsgb.org and search for âExam Announcementsâ.
Do you work with young people at a school, or perhaps with a youth group such as the Scouts, Guides or Cadets? Are you looking for an activity that provides hands-on learning opportunities for them? The RSGB National Radio Centre currently has availability for two private evening visits in December as part of the Societyâs activities for Youngsters on the Air month, or YOTA month as it is often called. Sessions typically last two hours and include an introduction to amateur radio, before the youngsters are split into smaller groups to complete a variety of activities. These can include Morse code, VHF communication using handhelds, shortwave radio communication and satellite communication. The group size is limited to a maximum of 12, and there must be one adult accompanying every four students. If youâd like to find out more about this unique learning opportunity, email the RSGB National Radio Centre Coordinator Martyn Baker, G0GMB via [email protected]
The next Bletchley Park 1940s weekend is taking place at the moment.

On Monday the 7th of October the RSGBâs Tonight@8 live webinar will be with Ian White, GM3SEK who will give a presentation entitled âAircraft Scatter, the Hitch-Hikers Guideâ. Aircraft scatter is about bouncing VHF and UHF radio signals off high-flying aircraft â effectively âhitching a rideâ with someone elseâs plane to extend your everyday working range up to 800km. For example, if you are one of the hundreds who get involved in the monthly UK Activity Contests on the 2m, 70cm and 23cm bands, you will already be using aircraft scatter routinely and it will be responsible for some of your best QSOs. So how does aircraft scatter work? And if itâs so useful, why havenât we heard more about it? Join the webinar live at 8pm on the RSGB YouTube channel or special BATC channel.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 19th of September 2024
It was a topsy-turvy time for HF propagation last week with a declining solar flux index and geomagnetic disturbances thanks to coronal mass ejections, or CMEs, from the Sun.
The solar flux index declined to the mid-160s, and the Kp index had a couple of excursions to more than 7. These were due to CMEs and the second, which occurred on Tuesday the 17th, was associated with the X4.5 solar flare on Saturday the 14th.
Luckily, it was 0300UTC when the CME hit the Earth, so only die-hard UK DXers were affected. With a G4 geomagnetic storm raging, the maximum useable frequency over a 3,000km path fell to less than 6MHz, but did manage to recover to 8.45MHz by dawn.
The rest of Tuesday was subdued with the maximum useable frequency never really getting above 21MHz. This is why the advice is often to avoid DXing when the Kp index climbs high, as the upper HF bands will likely be closed.
By comparison, on Thursday the 19th the Kp index was 2.67 and the maximum useable frequency over 3,000km was above 28MHz again.
NOAA puts the risk of another X-class flare at 10%, and an M-class event at 55%. So, we are not out of the woods yet.
Next week, the Space Weather Prediction Centre says the solar flux index may decline slightly but could then rise to be in the 232 to 240 range. Geomagnetic storming is predicted for the 26th to the 29th, when the Kp index could rise to 5.
Meanwhile, autumnal HF conditions should soon be kicking in with better propagation to North America. If the solar flux stays high, we can expect excellent 28MHz propagation, perhaps to the mid-west and Pacific states.
North-South HF paths, such as the UK to South Africa and South America, should also be good around the equinox period.
And now the VHF and up propagation news from G3YLA and G4BAO
The last week of Tropo gave us good conditions across the North Sea and up and down the country on the VHF and UHF bands.
It is very likely that there will be a big change of weather type over this weekend, ending today the 22nd, to a much more unsettled pattern with low pressure dominating during the coming week.
In fact, there will be a sequence of lows, fronts and showery interludes to set the template for next week. This means that rain scatter is a good candidate for propagation on the GHz bands, which could be useful on the evening of Tuesday the 24th during the SHF UK Activity Contest. Meanwhile, tropo takes a back seat for a while.
The solar activity continues to be of interest and, again, the message is to monitor the Kp index to keep one step ahead of events in case any aurora spring up.
Meteor scatter is mainly down to random activity, although the daytime Sextantids peaks on Friday the 27th of September, but with a low zenith hourly rate of 5.
For EME operators, Moon declination is positive and rising, reaching +29 degrees next Tuesday, so Moon visibility windows will continue to lengthen. Path losses are increasing as we passed perigee last week. 144MHz sky noise is moderate, dropping back to low next Thursday.
And thatâs all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 12th of September 2024
Last week showed that HF conditions are improving as we head into the autumn.
With a solar flux index still above 200, there was plenty of DX available to work. CDXC members reported working VP6WR on the Pitcairn Islands, KH8T on American Samoa and 3D2USU on Fiji, which is not a bad catch for early September.
A little closer to home, 9A168TESLA in Croatia has been popping up for short periods celebrating the 168th anniversary of the birthday of electrical pioneer Nikola Tesla. Watch DX Summit closely for operating times.
The daylight maximum useable frequency, or MUF, over 3,000 kilometres remains above 28MHz on the whole, although a raised Kp index tends to reduce this.
Geomagnetic conditions remained relatively calm with the Kp index below 3 all week. That changed on Thursday the 12th as material from a coronal mass ejection, or CME passed the ACE spacecraft in the early hours.
The solar wind speed increased to more than 500 kilometres per second and the Bz swung south. On Thursday the 12th, the Kp index was 5 and the Met Office Space Weather department was forecasting potentially unsettled conditions for this weekend, ending today the 15th.
At the same time an X-class flare occurred, with lowered MUFs due to increased D-layer absorption.
Two large coronal holes on the Sunâs surface are also now Earth-facing and threaten to add to the solar wind this weekend.
According to NOAAâs predictions, the solar flux index should stay in the 210 to 225 range next week, although a large number of spots are about to rotate off the Sunâs visible disk.
This may be compensated by an active region thatâs about to rotate into view. This has been emitting C-Class and lower-level M-flares and could potentially be the same region that produced several energetic eruptions off the far side of the Sun over the past week. Time will tell.
And now the VHF and up propagation news from G3YLA and G4BAO
The heavy showers at the end of last week produced some good rain scatter, but no QSOs in the UK were noted due to the showers not coinciding with GHz contests and few suitable home stations were active to take advantage of them.
After a gradual build-up of pressure over this weekend, ending the 15th, high pressure is suggested by most models during the coming week. However, there is some uncertainty about the position of the high.
Currently, models are favouring the north of Britain and this means that in the south, although still on the edge of high pressure, there could be a brisk northeasterly breeze, which may weaken the inversion prospects. Itâs not clear if the Tropo will be functioning in time for the 70MHz Affiliated Societies Contest today, the 15th, but should be helpful for the 1.3GHz UK Activity Contest on Tuesday the 17th and the 70MHz UK Activity Contest on Thursday the 19th.
Solar conditions are still likely to offer the chance of the occasional elevated Kp index, which is a good sign of possible aurora. It will be interesting to see how things evolve this weekend, ending the 15th, as a series of expected CMEs are due to reach Earth.
The amateur bands between 10m and 2m are the ones to check as well as looking out for âwateryâ sounding signals on the HF bands. Remember it doesnât have to be dark for radio aurora, so donât wait for dusk before checking.
Meteor scatter is mainly down to random activity in the coming week. However, with the September Epsilon Perseids stream still active until the 21st, having peaked on the 9th, conditions may be slightly enhanced.
For EME operators, Moon declination is negative but rising and going positive again on Wednesday the 18th. Moon visibility windows will continue to rise while path losses decrease as we approach perigee on Wednesday the 18th. 144MHz sky noise is moderate for the whole of next week.
And thatâs all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 5th of September 2024
Last week was underlined by continued high solar flux indices and excellent 10m band propagation to CY9C on Saint Paul Island near Newfoundland.
The DXpedition, which has now ended, was often at S9+ on 28MHz up to two hours after sunset. This may be a sign that better autumnal HF conditions are just around the corner and bodes well for the rest of the year.
The average sunspot number has now exceeded 200 for the first time in 23 years. This puts it significantly better than Solar Cycle 24 and it looks like there is more to come.
Propquest.co.uk reports that maximum usable frequencies over a 3,000km path are now often above 28MHz, so look out for DX on the 10m band. This will improve as the month goes on. September is a good month for north-south paths and paths to North America will improve as we head into October.
So, get your higher HF band antennas sorted out, as this autumn could be fun!
During the week just past, there were 21 M-class flares, but no X-class events. The Kp index has been under 5 all week, which no doubt helped HF propagation flourish.
Large coronal mass ejections, or CMEs, did occur on the 1st and 3rd of September, but these appear to be related to far-side events, well beyond the northwest limb and were directed away from Earth. But that active region is now rotating into view so buckle up for potential Earth-directed CME activity.
Next week, the Space Weather Prediction Centre suggests that the solar flux index will remain in the 240 to 250 range. Unsettled geomagnetic conditions are forecast for today, the 8th of September but, as we always say, keep an eye on solarham.com for up-to-date solar information as things are likely to change each day.
And now the VHF and up propagation news from G3YLA and G4BAO
The slightly enhanced Tropo conditions were welcome for the 144MHz UK Activity Contest on the 3rd of September. However, in the coming week, the opposite is now the case for many parts of the country as low pressure is set to dominate the weather charts.
There may be some weak ridges of high pressure nearby or even over northern Britain this weekend, but it is not looking great.
If pressed for a direction, it looks better across the North Sea to northern Europe and southern Scandinavia in the first part of the week.
Much of next week will have low pressure in control, and it will be worth looking for rain scatter on the GHz bands.
The solar side of things means that we should be alert to the chance of aurora if the Kp index rises. The autumn is often a good time of the year for these. It will be useful to monitor the Kp index, especially if you hear any signals sounding âwateryâ on the HF and LF bands.
Itâs always worth a reminder that the Sporadic-E season does not drop off a cliff at this time of year. That said, it does become very infrequent and restricted to lower bands or digital modes under the influence of jet streams. The southward paths to Iberia and the western Mediterranean look most promising next week for an out-of-season chance Sporadic-E event.
There is one small meteor shower this week. The September Epsilon-Perseids peaks with a low zenithal hourly rate of five tomorrow, the 9th. This shower produced unexpected outbursts in 2008 and 2013, but modelling indicates that 2024 activity should be nothing unusual.
For EME operators, Moon declination is now negative and falling further, reaching minus 29 degrees next Wednesday. Moon visibility windows continue to fall, as will peak Moon elevation, while path losses are decreasing after apogee. 144MHz sky noise increases from moderate today, the 8th, reaching over 2,500 Kelvin next Wednesday.
And thatâs all from the propagation team this week.

The news headlines:
RSGB collaborates on a special contact with the International Space StationThe RSGBâs Tonight@8 webinar autumn programme starts tomorrow, the 2ndThe RSGB is getting ready for National Coding WeekWe are delighted to announce that the Radio Society of Great Britain and ARISS, in conjunction with Girlguiding Surrey West and Brooklands Museum including the Innovation Academy, have been collaborating on a special event due to take place on Saturday the 5th of October. Girlguiding President, Her Royal Highness The Duchess of Edinburgh will attend a planned contact with the International Space Station as part of a visit to promote the engagement and involvement of girls and young women in science, technology, engineering and maths. Further details of the contact and the event will be announced in late September.
The RSGBâs autumn Tonight@8 programme starts this Monday, the 2nd of September. Brian Coleman, G4NNS will give an update on the Meteor Beacon Project which is a cooperation between the worlds of amateur radio and astronomy. The first phase of this project was completed in May 2022 when the UK meteor beacon GB3MBA went on the air from the Sherwood Observatory of the Mansfield and Sutton Astronomical Society. It enabled studies of meteor events over the UK using simple equipment and made possible a range of STEM projects featuring radio and astronomy. The second phase of the project, which Brian will describe in the presentation, is to develop a network of receivers streaming their data via a central server for detailed studies of individual meteor events. You can watch and ask questions live on the RSGB YouTube channel or a special BATC channel. To find out more go to the RSGB website at rsgb.org/webinars

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 29th of August 2024
We had a good week for HF propagation, at least until we had a Kp index of 5.67 on Wednesday the 28th. This was caused by the Bz component of the interplanetary magnetic field moving into a south-pointing position.
Luckily, it didnât last long and geomagnetic conditions were back to normal by Thursday.
The solar flux index remains above 200 with no sign of it dropping. But solar flare activity has not diminished either with 16 M-class flares over the past seven days and more than 60 C-class events. There remains a 55% chance of a further M-class flare and a 10% chance of an X-class event.
Tuesday the 27th saw some good activity on the upper HF bands with the 10m band opening up at times. VK has been heard on 28MHz in the mornings, which bodes well for the coming months.
The top DX choice this week has been CY9C on Saint Paul Island near Newfoundland. The team is active on all bands until the 5th of September using CW, SSB, FT8, Super Fox and RTTY. VOACAP Online shows that the 20 and 17m bands offer the best chance for a contact and are open from 0900 to 2000 UTC. The 30m band is another strong contender from 2000 to 1000 UTC.
Next week, NOAA predicts that the solar flux index will start at around 250 but could end the week at 275. As always, it estimates the Kp index will be at 2 all week, but this will depend upon coronal mass ejections, so keep an eye on solarham.com for daily updates.
If a solar flare and associated coronal mass ejections do occur, expect the Kp index to rise after about 48 hours, with a lowering of the maximum useable frequency.
And now the VHF and up propagation news from G3YLA and G4BAO
The autumn season usually brings thoughts of Tropo since areas of high pressure can often be a feature of this time of year. Most models predict that there will be high pressure moving in to offer Tropo conditions today, the 1st.
Thereafter, the models differ, and some bring low pressure over the country for much of the coming week, while others maintain a high-pressure story and the continuation of Tropo.
This is potentially useful for the 144MHz UK Activity Contest on Tuesday and Wednesday and, if it lasts, the 144MHz Trophy Contest next weekend along with the Backpackers contest on Sunday the 8th.
With the uncertain feel of the forecast at the moment, we may find rain scatter is the main option on the GHz bands.
Meteor scatter is again reduced to non-shower random events with just a minor shower, the Aurigids, peaking on the 31st of August. This shower has produced brief unexpected outbursts with a zenithal hourly rate of around 30 to 50 per hour in 1935, 1986, 1994 and 2019.
Random meteor flux is at its annual maximum in September with relatively good rates, especially during morning hours. Pre-dawn is the best time to try.
The solar conditions continue to provide chance auroras. Keep one eye on the Kp index and lock the frequency of some northern European beacons into your rigâs memory.
Lastly, it's the nominal end of the 2024 summer Sporadic-E season and the daily blogs on Propquest have finished. However, some years can produce surprise Sporadic-E events during the first week of September.
Moon declination starts the weekend still high but falling, going negative again on Thursday the 5th. So, Moon visibility windows will also fall, as will the peak Moon elevation.
Moon apogee is also next Thursday so path losses are still increasing. 144MHz sky noise is low until Monday but, shortly after moonrise that day, the Sun and the Moon become close in the sky and continue to be until after moonset on Tuesday.
This means sky noise will be very high, especially at VHF, due to wide antenna beamwidths.
And thatâs all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 22nd of August 2024
We had yet another week with a high solar flux and relatively calm geomagnetic conditions.
The solar flux index ended up at 239 on Thursday the 22nd, while the Kp index has been below 4 since Sunday the 18th. There are currently 11 active sunspot regions on the Sunâs surface and there is a 20% chance of a major X-class solar flare according to the NOAA Space Weather Prediction Center.
There are signs that HF propagation may be improving, but it will probably be another month or so before we see any large change. This is due to the summer doldrums that see the ionosphere harder to ionise due to a change in its chemical composition.
By mid to late September, we will start to see a change to autumnal conditions and DX will start to open up again on the higher bands. Having said that, there is still DX to be had. The N5J DXpedition to Jarvis Island in the Pacific Ocean proved that the DX is workable, but the path was mainly open to well-equipped stations with beams and linear amplifiers.
15m remains the best DX band and there are occasional openings on the 12m band. The 10m band may come into its own as we head into September and October.
According to the NOAA Space Weather Prediction Center, solar cycle 25 likely reached its highest sunspot number yet of at least 299 on the 8th of August. This may increase further, but we may be close to solar maximum.
Next week, NOAA predicts that the solar flux index will remain around 200 to 210. Geomagnetic conditions will depend almost entirely on the occurrence of coronal mass ejections, or CMEs. And, as we are at a particularly active part of the solar cycle, flares and CMEs are very prevalent.
And now the VHF and up propagation news from G3YLA and G4BAO
The overview for the coming week is that, although some fronts will affect the north and west at times, there are only a few that reach down to the southeast of Britain. This means that rain scatter is more likely in northern areas.
There will be weak high pressure over southern areas for much of the coming week and, although not enough for a full-blown Tropo event, conditions should be a little âup', especially for paths into the near continent or across the North Sea.
Meteor scatter is back to a more random approach since the broad peak of the August Perseids comes to an end. The solar conditions mean that auroras can be a possible element of operating excitement in the coming week. Remember to look out for a disturbed Kp index value of 6 or greater.
The last part of the sporadic-E season is playing out this week taking us to the end of the month. These 'last hurrahs' are usually characterised by QSOs of very limited duration on the 10m band, or perhaps up to 6m, and mainly over the southern half of Europe.
This usually favours southern UK stations but, notwithstanding the previous comments, some years have seen isolated Sporadic-E events in the first part of September. But they are certainly not reliable.
Moon declination is positive but still rising, reaching maximum on Wednesday, so long Moon visibility windows and high peak elevations continue. We are past perigee now, so path losses are increasing again. 144MHz sky noise is low but increasing to a moderate 500 Kelvin on Wednesday before falling back to low at the end of the week.
And thatâs all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 15th of August 2024
Last week was notable for its auroral activity, high solar flux index and variable HF conditions.
Monday the 12th saw the Kp index rise to 7 as coronal mass ejection material struck the Earth, sparking visible aurora as far south as Cornwall. But by lunchtime on Tuesday things were back to normal with a Kp index below 2.
The rest of the week remained fairly settled with the occasional blip up to a Kp index of 4. Meanwhile, HF conditions have been variable with N5J on Jarvis Island in the Pacific being the main DX being chased. This has turned out to be a difficult catch for all but the better-equipped stations in the UK.
The operators are active on SSB, CW and FT8, using the SuperFox and Fox and Hound modes, and are working until the 20th of August. So, have a listen and give them a call.
The peak times are around 0500 to 1200UTC for a short-path contact, and around 1800UTC for a long-path contact. See jarvisisland2024.com for frequency details and the latest news.
Otherwise, the maximum useable frequency, or MUF, over a 3,000km path has been more than 18MHz and often 21MHz during daylight. Night-time MUFs have been more than 14MHz when there have been no geomagnetic disturbances.
Next week, NOAA predicts that the solar flux index will start at around 260 but decline to perhaps 210 as the week progresses. This is still enough for some good HF propagation. Predictions are less certain about geomagnetic disturbances, other than a rise on the 22nd of August.
Solarham.com predicts that a coronal mass ejection associated with an X1.1 solar flare last Wednesday will pass Earth by the 18th of August, so we may expect the Kp index to rise today.
And now the VHF and up propagation news from G3YLA and G4BAO
The period of alternating hot summer days and unsettled spells with rain or heavy showers looks like the recipe for the coming week.
The weak ridges of high pressure could prove useful for some Tropo on occasion. In the summer months, Tropo is often more pronounced over nearby waters such as the North Sea and south across Biscay or the English Channel. But it can also feature overnight and, if we are lucky, may help with the 23cm UK Activity Contest on Tuesday the 20th.
These high-summer active fronts or heavy showers can be very good for rain scatter. Since temperature plays an important role in the intensity of summer thunderstorms, the resulting rain scatter is often best in the afternoon and early evening. On rare occasions, daytime storms can drift north from France to be over the UK during the night.
The Perseids meteor shower peak has passed now, with some good QSOs reported. Itâs a broad shower and there should still be some worthwhile meteor input to play meteor scatter next week.
The recent solar conditions have produced a disturbed Kp index and there were some impressive visible and radio auroras from 10m up to 6m last week. It's worth watching out for a high Kp index above, say, 6 and be ready to listen for radio Aurora in the afternoon.
Lastly, the Sporadic-E season struggles on with varying degrees of success, but it's still very much a player for another two or three weeks. The upper air charts show that there should be some strong jet streams and thus potentially good sources of the turbulence required for Sporadic-E. Use the Propquest.co.uk NVIS graphs to see if Dourbes in Belgium is showing any spikes.
Moon declination is negative but rising now. It wonât go positive until Wednesday, so short Moon visibility windows and peak elevation continue to increase. Wednesday is also perigee, the Moonâs closest point to Earth and when path losses are at their lowest. 144MHz sky noise is moderate to low over the coming week.
And thatâs all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 8th of August 2024
Well, so much for the experts! NOAA predicted that the solar flux index would fall last week when it increased to a whopping 303 on Thursday the 8th.
But this high solar flux number was accompanied by a strong risk of solar flares, so it was not all plain sailing. We have had 15 M-class and two X-class solar flare events over the past three days and the threat remains high.
Coronal mass ejection activity on Wednesday resulted in NOAA and the Space Weather Prediction Centre warning of possible moderate G2 geomagnetic storming towards the later part of week ending the 11th of August. This could see the Kp index rise and the maximum usable frequency fall.
Hopefully, conditions will improve after the weekend.
Last week was a good one for HF propagation with a high solar flux index and low Kp index. The 10m band was open to Brazil in the late afternoon, and this appeared to be F2-layer propagation and not multi-hop Sporadic-E.
Meanwhile, the 15m band has perhaps been the DX band of choice with long openings to the Far East, at least on FT8, and North America at the same time. HF conditions should also improve as we move into September, but more on that closer to the time.
Attention now shifts to N5J on Jarvis Island, an uninhabited 4.5-kilometre-squared coral island in the South Pacific Ocean, about halfway between Hawaii and the Cook Islands. The DXpedition is active on all bands and their website at Jarvisisland2024.com can provide you with personalised propagation forecasts â let us know if you work them.
Using Proppy at soundbytes.asia or VOAcap at voacap.com, shows that 20, 17 and 15m short-path seem to offer the best chance of working the DXpedition, with morning openings from around 0600 to 1000UTC. There is also a potential long-path opening between 1800 and 2000 UTC, with a possibility of the 10m band at 1900 UTC. Both are near polar paths and may be adversely affected by a high Kp index.
CDXC members with good stations have already reported QSOs with N5J on the 17m band using FT8.
Next week, NOAA predicts the solar flux index will be in the range of 185 to 240. Geomagnetic conditions will depend on whether we have more solar flares and coronal mass ejections, and the chance of those remains high.
An Earth-facing coronal mass ejection could send the Kp index soaring, and that will no doubt lead to reduced maximum useable frequencies and noisy bands. So, fingers crossed for more quiet geomagnetic conditions and low Kp indices!
And now the VHF and up propagation news from G3YLA and G4BAO
The summer tries to deliver but, overall, the pattern has a rather unsettled flavour to it for the coming week.
On the positive side, we see a transient area of high pressure crossing southern Britain over this weekend, ending today the 11th. This could give some Tropo conditions but, after this, the Atlantic westerly flow brings a succession of fronts and showers to most areas.
In terms of propagation, this suggests that rain scatter will have the best of it in the week ahead.
The Sporadic-E season remains a good fallback and surprised us in East Anglia mid-morning on Tuesday the 6th of August with 144MHz Sporadic-E propagation to YU, HA, 9A and LZ moving around towards Italy as the opening progressed.
All were workable with 100W and a white stick antenna on FT8. For the coming week, the jet stream activity will probably start by favouring paths to Scandinavia and the Baltic. Later in the week, a new jet stream will drive southeast into Iberia, opening up chances for paths to EA and CT.
The Perseids meteor shower this week will provide welcome new fuel for Sporadic-E and, as a result, like most years, weâll see openings into the first week of September.
The meteor scatter highlight is the Perseids meteor shower, which peaks on Monday and Tuesday. So, there are plenty of opportunities to try a new mode or fill in some missing grid squares if you are already involved in meteor scatter.
Many websites explain what it's all about, but one to start you off is g7rdx.co.uk Also, try looking for videos of meteor activity on SDR radios to get an idea of what it all sounds like.
The solar conditions lately have been rather disturbed. It would not be surprising if the Kp index was to suggest that aurora could be a possibility if it gets to 5 or higher.
Moon declination is negative and reaches minimum on Thursday the 15th, which means there will be short Moon visibility windows and low peak elevation. Path losses will decrease throughout the week and 144MHz sky noise is low over the weekend, but climbing to reach a high peak of over 3200 Kelvin on the 15th.
And thatâs all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 1st of August 2024
We had another week of high solar flux but unsettled geomagnetic indices.
The solar flux index, or SFI, was above 200 from the 27th of July onwards. There was a worry that multiple coronal mass ejections, or CMEs, might push the Kp index up during the week. In the end, the Kp index didnât rise above 5. But why was that?
The first of several CME eruptions was expected to pass Earth on the 29th of July. The solar wind speed increased from 330 kilometres per second to around 450 kilometres per second, but only a brief period of minor G1 geomagnetic storming was observed. The solar wind stream was fast, at more than 450 kilometres per second, but its frozen-in magnetic field was predominantly North-facing or neutral. So, it didnât couple with the Earthâs magnetic field, and we ended up with a Kp index of only 5.
If we had had a south-facing interplanetary magnetic field or Bz it could have been much worse.
As it was, the ionosphere was affected on Wednesday the 31st of July. However, by 1830UTC things were back to normal, with a critical frequency of 7.4MHz, which gives a maximum usable frequency over a 3,000km path of around 21MHz.
Further disturbances on Thursday the 1st of August saw the Kp index rise to 5 again, but it was short-lived and only lasted for one three-hour period.
So, we are still in a period of high solar activity, with numerous M- and even X-class flares, coronal mass ejections and high sunspot numbers. With a cluster of sunspots rotating into view right now, it should be an interesting week ahead!
The SFI is predicted to fall next week, perhaps to the 180s or 190s. Meanwhile, HF propagation remains good at times, although we are still feeling the effects of the summer doldrums, with reduced daytime maximum usable frequencies.
Keep an eye on solarham.com for up-to-date geomagnetic information.
The 15m band is still the favoured daytime DX band, with occasional F2-layer openings on the 12m and even 10m bands. However, most 10m openings are still due to Sporadic-E.
And now the VHF and up propagation news from G3YLA and G4BAO
The weather patterns that drive some of our radio propagation conditions are in the process of changing.
As we ended the previous week, there were still regions of high pressure near enough to southern areas for some useful Tropo across the North Sea, English Channel and south over Biscay.
The slow change towards low pressure dominating the charts will be gradually extending its influence over the whole country as we move into next week, so less Tropo and more interest in rain scatter.
This has been available over some northern areas recently and from heavy thunderstorms in the south. It is probably going to be a useful mode for exploring the GHz bands in the coming week, particularly where heavy thundery rain occurs.
Meteor scatter is also a worthwhile pursuit since we are still in the broad period of the Delta Aquariids meteor shower and that eventually blends into the August Perseids later in the month.
The solar conditions continue to be challenging and the Kp index has been high enough to make it worth thinking of checking for auroral conditions â either fluttery signals on the LF bands overnight, or perhaps auroral conditions on the VHF bands. The Kp index gets mentioned on all propagation websites these days, but spaceweather.com is a good source for that and much else too.
Sporadic-E is still worth checking out and, although the summer jet stream pattern is usually pretty weak, it is still there, and the position is perhaps a bit more northerly now than earlier in the summer. This means that paths towards the east to Scandinavia and the Baltic might be worth looking for, although other directions can still happen, of course.
Moon declination started to fall from Friday the 2nd, so Moon window lengths and peak Moon elevation will follow suit. With apogee on Thursday the 8th, path losses will be at their highest for the month. 144MHz sky noise is low until the evening of Saturday the 3rd when we see the Moon and Sun close in the sky until moonset on Sunday. After that, the sky noise is low.
And thatâs all from the propagation team this week.

GB2RS News
Sunday the 28th of July 2024
The news headlines:
Two new Directors have been co-opted to the RSGB BoardThe RSGB welcomes two new Regional Representatives The RSGB National Radio Centre is looking for volunteersWhen Paul Nichols, M0PVN resigned as an RSGB Director in May, it created a vacancy on the Board. The Board decided that it was in the Society's interests to expand the Board to nine people to help implement the Societyâs strategic priorities. Under Article 37 it has co-opted Peter Bowyer, G4MJS and Peter Ransom, M0SFZ as Directors to serve until the 2025 AGM. Peter Ransom recently passed his Full licence so that he could build and tinker with RF equipment, to add to his ongoing interest in writing amateur radio software and designing his own PCBs. He has a passion for technology and communication and has had a career that combines technical expertise with strategic vision. He hopes to use that knowledge and experience to help the Board to ensure that the Society remains relevant to the amateur radio community. Peter Bowyer has been in and around IT all his career and currently helps organisations with their Agile development strategies. He has been licensed for 45 years, but says he is still learning new things. He's an avid contester, having served on the VHF Contests Committee, he has written a column for RadCom and is a past chair of the UK Six Metre Group. The RSGB welcomes them both to the Board.
The RSGB is delighted to announce the co-option of two Regional Representatives. Peter Lowrie, MI5JYK is based in Region 8 and Brian Woolnough, M5ADQ in Region 12. They will serve in these roles until the RSGB 2025 AGM. You can see contact details for either of them, or any member of the Regional Team, on the RSGB website at rsgb.org/regions

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 25th of July 2024
We had yet another week of high sunspot numbers and low geomagnetic disturbances, but will it last?
We dodged a bullet last week after a weak coronal mass ejection, or CME, on Tuesday the 23rd failed to generate a geomagnetic storm. This was from a faint halo CME observed on Sunday, which was much weaker than expected when it hit Earth.
A further M2.4 flare, near the eastern limb on Tuesday, produced a coronal mass ejection, but that was directed away from Earth.
So, we ended the week with a Kp index that never rose above 2, despite up to 19 M-class solar flares occurring. Our luck must run out some time!
The main HF DX this week has been the K8R DXpedition on American Samoa. This has been workable on all bands from 20 to 10m, especially using FT8. They have been trialling a new Super Fox mode on FT8. If you are interested in using this mode, you will need the latest version of the WSJT-X software.
Daylight maximum usable frequencies, or MUFs, over a 3,000km path have reached more than 24MHz, with 28MHz available at times on some paths. This will, no doubt, improve as we head towards the autumn.
Nighttime MUFs over a similar path length have exceeded 14MHz and often reached 18MHz at times. Make the most of the nighttime openings as they will die off as we head towards the end of the summer.
Next week, NOAA predicts the solar flux index will be in the range of 165 to 175 and the Kp index will be a maximum of 2 all week. As ever, this will be dependent on any solar flares and associated CMEs. A CME could easily push the Kp index up and the MUF down.
Four sunspot groups have just rotated into view so keep a close eye on them on solarham.com At least one is classed as âgrowingâ and could be a contender for trouble over the next week by way of solar flares and CMEs.
And now the VHF and up propagation news from G3YLA and G4BAO
The area of high pressure which develops over this weekend will bring the prospect of Tropo conditions at the start of the new week.
The high will drift slowly east towards Denmark by midweek but could still provide the chance of Tropo conditions across the North Sea until Wednesday.
Meanwhile, a weather front will reach northwest Scotland on Monday and edge slowly south whilst a small thundery low develops near the southwest of Britain. This combination will bring a gradual transition to more unsettled weather with a chance of rain scatter on the GHz bands for the second half of the week.
The Delta Aquariid meteor shower is active from the 12th of July to the 23rd of August. With no noticeable peak, it is expected to reach its maximum rate of 25 per hour on or around the 30th of July.
We should have more than just random meteors to use for meteor scatter operation, so it's worth trying meteor scatter on the VHF bands. Also, given clear skies and darkness over the next few weeks, it's worth having a look out for them with the naked eye or photographically.
This extra input of meteors may well improve the prospects for Sporadic-E, which have perhaps seemed a little less than enthusiastic recently. Meteor debris from meteor showers, or random meteors, provides the fuel for Sporadic-E. These ionised trails in the E region above 100km can be affected by wave motion caused by jet streams much lower down at around 10km.
Fortunately, there are a number of useful jet streams on the forecast charts for next week with a slight preference for paths to Scandinavia and eastern Europe.
Moon declination is positive and rising, reaching maximum on Thursday the 1st of August, so Moon windows are long with high peak Moon elevation. We passed perigee on the 24th so path losses are on the increase. 144MHz sky noise is low to moderate all week.
And thatâs all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 18th of July 2024
We had another great week in terms of HF propagation. The solar flux index was at a remarkable 224 on Thursday the 18th, and the Kp index had been consistently in the ones and twos all week.
It doesnât get much better than this, HF-wise, although it's a shame it's not autumn with the associated good HF autumnal propagation.
Given that we are in the summer HF doldrums, there has been a lot of DX on the bands. 15m has been very good during late afternoons, and open to all continents, with Australia, Asia, Africa, North America and South America all workable on FT8 at the same time.
On Thursday the 18th, there were 17 active sunspot regions visible, which contributed to the high solar flux index. Two X-class solar flares brought short-term solar fadeouts on the 14th and the 16th, but any associated coronal mass ejection has been mainly directed away from Earth.
For those new to HF propagation, this is good news. Remember, a high solar flux index is generally good, while a high, perhaps more than four, Kp index is generally bad.
Daytime maximum usable frequencies, or MUFs, over a 3,000km path have been consistently above 21MHz. Nighttime MUFs have been more than 14MHz, and often 18MHz, at times.
But will this continue? Probably not.
Of the 17 visible sunspot groups, six are classed as âgrowingâ. There have been coronal mass ejections from sunspots on the edge of the Sun, but they have not been Earth-directed. But, as these spots rotate to be Earth-facing, a coronal mass ejection could be more problematic.
Next week, NOAA predicts that the solar flux index may fall, perhaps into the 170s to 180s range.
The Kp index is predicted to be around 2, but if we do have an Earth-facing coronal mass ejection that could easily climb to 4 or 5, with an associated drop in the maximum usable frequency.
So, will it be another week without a high Kp index? Maybe that is too much to hope for!
And now the VHF and up propagation news from G3YLA and G4BAO
Last week ended with a decaying high over Germany and fronts pushing in across western Britain. With such warm air over the UK at first, even temporarily, there will be a reasonable chance of Tropo over nearby cooler waters around our coasts, especially along the English Channel and southern North Sea.
Incidentally, for anyone taking a VHF rig with them on holiday to the Mediterranean resorts, you can expect typical summer semi-permanent, very strong maritime Tropo ducts over any sea path to neighbouring islands or countries.
Returning to the UK, we have a series of fronts and lows lined up for the coming week. In summer months these can often have a showery element to them, so expect some heavy rain and thunder at times, but at least there'll be rain scatter to make up for it!
Meteor scatter is again a random experience, with no major showers this week. Try around, or just before, dawn for best results. The solar conditions have been all over the place with flares and weak auroral responses, but nothing dramatic for VHF radio.
Sporadic-E, on the other hand, has done fairly well for digital mode activity, especially for transatlantic paths, but is slightly subdued where higher signal levels are required for SSB and CW. Although the weather is expected to be unsettled, the jet stream activity is less widespread than recently. If anything, the western side of Europe seems in a better spot with quite good options for paths to Iberia. Remember, most years will see activity into the first week of September, so donât give up yet.
The Moon is at minimum declination on Friday the 19th so we start the week with short Moon windows and falling path losses as we approach perigee on the 24th. Perigee is the point at which the Moon is closest to the Earth. 144MHz sky noise starts very high but declines to medium next week.
And thatâs all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 11th of July 2024
We had another week of reasonably settled geomagnetic conditions and a high solar flux index.
The solar flux index was at 214 on Thursday the 11th, while the Kp index has been around 2 to 3 all week. Thatâs generally good news for HF.
However, a small coronal hole is now facing Earth and a solar wind stream flowing from this zone was predicted to reach Earth by the 13th of July. This could result in an elevated Kp index and lower maximum useable frequencies, or MUFs for short. It probably wonât last too long, so expect conditions to be back to normal by tomorrow, the 15th.
Active region 3738 is dominating the Sunâs surface but has only been the source of minor C-class solar flares and will remain a threat for moderate M-class flares. All other regions have been mostly stable.
The daytime MUF over a 3,000km path has often exceeded 24.9MHz, with some better-equipped stations reporting contacts into Australasia on the 10m band.
Night-time MUFs over a similar distance are still consistently above 14MHz. Make the most of this as they are likely to drop as we head out of summer and into autumnal conditions.
The MUF is extrapolated from the Dourbes ionosonde data and should only be used as a guide â it may often be higher, especially in some directions.
The most sought-after DX this week has been K8K/K8R in American Samoa. The DXpedition is testing out all systems on all bands, using CW, SSB and FT8, ahead of the upcoming Jarvis Island DXpedition. The station has been worked from the UK on the 30 to 10m bands, mainly by well-equipped stations, and has been testing the FT8 Superfox mode with some success.
Otherwise, contestants in the RSGBâs 80m SSB Club Championship on Wednesday the 10th reported fair conditions, but a very, very noisy band. Noise is often a limiting factor, especially on the lower HF bands.
Next week, NOAA predicts that the solar flux index may decline to the 180 to 190 range. Geomagnetic conditions may be unsettled today, the 14th, with a Kp index of 4 at times. The second half of the coming week should be more settled, as long as we donât have a coronal mass ejection.
And now the VHF and up propagation news from G3YLA and G4BAO
The overall picture is of unsettled weather still being around for the coming week, but there will be some temporary moments of weak high pressure to alleviate incessant rain.
As we end the current week, pressure will rise over western areas bringing a chance of Tropo for paths down the Irish Sea and across Biscay. There will also be a second period of high pressure for a time in the middle of next week, favouring the south. This gives us at least a chance of Tropo for this weekâs UK Activity Contests on the 23cm and 4m bands.
The âunsettledâ part of the story is worth noting, especially if we get some heavy thundery downpours, which should be great for rain scatter. Continuing with scatter modes, there is always meteor scatter as a diversion and the advice is to look in the early hours before daybreak when random meteors are more likely.
Solar conditions are still not entirely settled so there remains a chance of aurora should the Kp index rise to 5 or more. The Sporadic-E season is still doing good business within Europe, but it feels as though itâs not been quite so noticeable as during June for UK stations.
The jet stream pattern is trying to help next week with several useful segments over northwest Europe, which should improve the chances of Sporadic-E paths from the UK into the continent.
Moon declination went negative again on Friday the 12th, which also corresponds to apogee, the point at which the Moon is furthest from Earth. So, Moon peak elevation and path losses will continue to fall again next week. 144MHz sky noise starts low early next week rising to a high of 2100 Kelvin on Friday.
And thatâs all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 4th of July 2024
After a rough spot last weekend, the Sun has since behaved itself, allowing HF propagation to get back to normal. To recap, the Kp index hit 7.67 on Friday the 28th of June, thanks to incoming plasma from a coronal mass ejection. For a time, it looked like we might have a repeat performance of the 10th of May when the Kp index hit 9 and there was a visible aurora across the UK.
This time around, however, conditions calmed down again and 24 hours later the Kp index was back to 2.33. Since then, the Sun has remained calm with only two M-class and zero X-class flares, and the Kp index is back in the 1 to 3 range.
This means that the ionosphere has had a chance to build up and we have been seeing MUFs over a 3,000km path exceeding 21MHz and often reaching 24MHz. Thatâs pretty good considering we are in the Summer HF doldrums.
An analysis of the Sun's active sunspot regions shows that two are growing, five are declining and one is stable.
WSPRNet.org shows that signals have been getting to the UK from Australia, New Zealand, Japan and the Far East on the 15m band, while 28MHz is still mainly open to short-hop Sporadic-E contacts across Europe.
The solar flux index has declined over the past week and was sitting at 167 on Thursday the 4th of July. Next week, NOAA predicts it will remain around the 170 mark, with quiet geomagnetic conditions.
However, solar flares and coronal mass ejections remain hard to predict so keep an eye on Solarham.com and Propquest.co.uk for a real-time view of solar and geomagnetic conditions.
And now the VHF and up propagation news from G3YLA and G4BAO
The weather sequence to the end of next week is much like an autumn pattern in that the story is all about areas of low pressure, showers and weather fronts. None of this suggests that Tropo will be a feature of the weather. In fact, high-pressure systems simply do not appear on the charts at all.
We can leave rain scatter on the list and, since it is technically summer, or meant to be, there is a lot of energy in any showers. Indeed, some may be heavy and thundery and are probably good rain-scatter candidates. Meteor scatter, in the absence of major showers, is most likely around the dawn period when random meteors tend to be more prevalent.
The solar conditions continue to offer much variability and it is always worth checking for elevated Kp index values, which can be a signal for aurora to occur. As a general guide check the bands when Kp reaches 5 or higher.
The Sporadic-E season continues, although recently there have been some higher-than-ideal Kp indices, which unlike for aurora need to be at lower values, say below a Kp index of 3, for ideal Sporadic-E conditions.
The other ingredient that tends to promote Sporadic-E is the presence of jet streams in the upper atmosphere around 10 to 15km up. It is believed that these can generate atmospheric gravity waves that can propagate up to the E region at 110km where they become part of the process for making Sporadic-E.
This unsettled autumn-like weather is providing plenty of jet streams, so it continues to be worth checking for Sporadic-E. A quick look at the upper air pattern suggests that paths towards Scandinavia and the Baltic may be productive, and perhaps to Iberia later next week.
Moon declination is close to maximum positive this coming weekend so Moon peak elevation will be high. Moon apogee is on Friday the 12th so EME path losses continue to increase. 144MHz sky noise is low all week.
And thatâs all from the propagation team this week.

The news headlines:
The IARU HF Championship is coming upLearn about the QMX+ transceiver at the next RSGB Tonight@8 webinarThe Examinations Standards Committee has published its annual reportThe IARU HF Championship contest will be held between the 13th and 14th of July and there is a great opportunity for you to get involved in a different way this year. During the contest, âHeadquarters Stationsâ represent their countries and the RSGBâs station GR2HQ will be run by a network of about a dozen stations around the UK and islands. This year, the RSGB Contest Committee has introduced a new challenge to encourage individual stations to work the GR2HQ station on each band-mode slot. You will be able to submit your log, including QSOs with GR2HQ, to the RSGB contest robot for the GR2HQ Challenge. If you include your club or group name when you submit your log, each QSO with GR2HQ will count towards an aggregate score for your club or team. There will be two results tables, one for individuals taking part and one for clubs, so your QSOs can contribute to both! Why not encourage your club members to take part in this special challenge whether they are regular contesters or not. By contacting the GR2HQ station youâll also help the RSGBâs position in the contest â last year the RSGB came third and the Society would love to improve on that result. You can read more in the June RadCom feature on the GR2HQ Challenge and you can see the rules on the RSGB website at thersgb.org/go/gr2hq

The Examinations Standards Committee has published its annual report, relating to activities in 2023. Whilst the report shows that in 2023 there were fewer candidates across all licence levels, the number of people taking exams so far in 2024 has increased significantly. Another item in the report relates to the preparations that are being made to release the bank of questions for the Full licence exam. The ESC Chair, Tony Kent, G8PBH says that it has long been recognised that a review of the question bank, particularly at Full level, is well overdue and has been delayed multiple times by things such as the need to revise the syllabus for EMF and the new licence changes. Reviewing the question bank is the next priority of the ESC and the Exams and Syllabus Review Group and will begin on the 1st of September when Syllabus 1.6 is up and running. The ESC and ESRG believe it is better that this review is conducted before the bank is published as this should reduce the workload on the community and the exams teams in making and responding to queries on questions that may be withdrawn. They are hoping to release the questions in January 2025. To see the full ESC report go to rsgb.org/esc and click on the minutes, papers and reports tab on the right.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 27th of June 2024
We had another lucky week with quite a high solar flux index, low Kp geomagnetic numbers, few solar flares and no coronal mass ejections, or CMEs, of note. In fact, you couldnât ask for better!
But is that all about to change? With nine active solar regions on the Sunâs surface and the return of old region 3664, now renamed 3723, it would be a brave person to suggest otherwise.
So, letâs take a closer look at the Sun. Of the nine active regions that are visible, four are classed as stable, one is classed as declining and four are classed as growing.
With a solar flux index of 181, there is plenty of UV radiation around. However, we are currently in the summer doldrums so maximum useable frequencies, or MUFs, are lower than they are in the Autumn and Winter. In other words, we are not going to see a return to reliable worldwide DX conditions on the higher bands until mid to late September.
There is currently only a 5% chance of a strong X-class solar flare, although a bright coronal mass ejection was observed for a second day off the Sunâs west limb. This was directed away from our planet so shouldnât affect us.
NOAA predicts that the Kp index could rise due to CME arrivals from an event that left the Sun on the 24th of June. Expect a Kp of 4 or 5, with a reduction in the MUF until the geomagnetic disruption abates. It also predicts that the solar flux index will remain in the region of 190, hopefully with a low Kp index after the ionosphere settles again.
MUFs over a 3,000km path are generally between 18 and 23MHz during daylight and around 18MHz at night. This means that for the next month or so we may expect 14MHz to remain open throughout the night.
And now the VHF and up propagation news from G3YLA and G4BAO
The current week finishes with a return to unsettled weather and cooler air, after a brief taste of summer, particularly in the south of Britain.
There will be lows drifting in from the Atlantic during the coming week, as well as the occasional passing weather front. Although there was some Tropo last week, during the brief period of high pressure, this is unlikely to be repeated in the coming week.
Therefore, we have a continuing random chance of some rain scatter, but you will need one of the many online weather radar displays to track the scatter regions down. Since next week also looks windier, you might have to keep one hand on the rotator!
Meteor scatter is once again down to random events, which means an early start in the shack to capture the higher rates in the early mornings.
The solar conditions continue to keep trying to creep into VHF affairs with a higher Kp index and thoughts of radio aurora, but it's probably not a strong shout.
Now to our last item â Sporadic-E. There is still the broad summer Sporadic-E peak, which extends into the first week of September in a good year, so you have plenty of time. It will not always be there but, in a test analysis of Dourbes data in June 2022, 84% of the days reached 10m, with 18% up to 6m and around 10% to 4m or above. This makes it worth using the 10m band to highlight the regions of activity and then check the 6m beacons in case it strengthens to bring in the higher bands.
Moon declination goes positive again this coming weekend so Moon peak elevation and window lengths will increase. Perigee was on Thursday the 27th so EME path losses are increasing again. 144MHz sky noise is low at the start of the coming week and moderate later. From Friday afternoon on the 5th of July to midday on Saturday, the Moon and the Sun are very close in the sky, meaning high noise for all but the narrowest beamwidth antennas.
And thatâs all from the propagation team this week.

The news headlines:
RSGB Convention workshops and practical sessions â what would you like?RSGB Team interviewed by ICQ Podcast at the Dayton Hamvention in MayDonât forget to try the updated RSGB Discovery SchemeDo you like making things? Are you interested in finding out more about the Raspberry Pi or programming an Arduino? Have you heard about the NanoVNA and DragonOS but donât know where to start? The RSGB wants its 2024 Convention to offer practical sessions to help radio amateurs try something new, develop their skills and go away inspired! If you can offer to run a workshop or a practical session over the weekend of the 11th to the 13th of October, or youâd like to take part in one, please email the RSGB Convention Team via [email protected] by the 3rd of July. As part of its strategy, the RSGB wants to ensure that this prestigious annual event not only meets the needs of its members but also helps every radio amateur to share their love of the hobby with others.
Members of the RSGB Team, including RSGB President John McCullagh, GI4BWM and RSGB General Manager Steve Thomas, M1ACB, had a successful time at the Dayton Hamvention in May. The event was a brilliant opportunity to engage with radio amateurs from around the world and it resulted in 132 people joining the RSGB. It also provided several media opportunities with podcasters, YouTubers and local news outlets. Martin Butler, M1MRB from ICQ Podcast was one of those who interviewed the President and the General Manager. The interview covered a wide range of topics, from using the new licence conditions as part of outreach, to the RSGBâs role in defending the spectrum and even to the RSGB Presidentâs amateur radio activities with both RAYNET UK and SOTA! For the full interview go to Episode 432 on icqpodcast.com and listen just before two hours into the episode.
Have you tried the updated RSGB Discovery Scheme? Now called the Discovery Logbook, there are fewer requirements, an easy-to-follow programme and exciting links with external organisations such as Parks On The Air and Worked All Britain. There are also some great RSGB Awards to work towards if youâd like to include those in your programme of activities. As a relatively new radio amateur, Jim, ME7HEF had found that the sheer breadth of the hobby made it a little difficult to know where to start. The Discovery Scheme gave him a simple structure to try various aspects of amateur radio and he has enjoyed it.

You will need experience of editing material from a wide range of sources and working to deadlines, as well as having attention to detail. An understanding of desktop publishing programs such as InDesign will be helpful along with knowledge of the breadth of amateur radio in the UK today. If you are interested in this post, please email [email protected] with an appropriate CV or covering statement of your abilities.
Last weekend was 1940s weekend at the Bletchley Park Museum. The RSGB National Radio Centre, or NRC, supported the event by hosting the World War Two Special Operations Executive radio station, GB1SOE. The station, operating on the 40m band, attracted lots of visitor attention, as did GB3RS which was busy on the air as part of the Museums on the Air weekend. NRC volunteers made QSOs and invited visitors to pass greetings messages. If appropriate, the volunteers used the new licence conditions to allow visitors to run QSOs themselves under supervision. The weekend was a huge success and 1,211 people visited the RSGB National Radio Centre. The Society would like to thank all the NRC volunteers who delivered such an enjoyable weekend.

The Bath Based Distance Learning team is busy enrolling students into its pre-course classroom for its forthcoming course for the Full Licence exam. The team has received enquiries about whether its course is suitable for the Direct to Full exam. The course content focuses on the Full level syllabus items, which are only a part of the Direct to Full syllabus. Learners are expected to know the Foundation and Intermediate material already. Parallel study is possible, but the Bath Based Distance Learning Full Licence course alone would not be sufficient to ensure a pass in a Direct to Full exam. More details can be found in the latest edition of RadCom, but please note that the email address provided to RadCom was incorrect; anyone wanting details of the Bath Based Distance Learning course should email Steve, G0FUW, using [email protected]

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 20th of June 2024
We had a relatively quiet week, with the Sun generally being settled. There were coronal mass ejections, but they were on the far side of the Sun and not Earth-directed.
There were no X-class flares, although we did have a few C- and M-class events.
The solar flux index declined to 167 but has since recovered and stood at 196 on Thursday the 20th. Active regions 3712, 3713 and 3716 are all large and 3712 has been emitting flares. However, all three regions will soon rotate out of view, so should not be a threat in the coming week.
As such, HF conditions have been reasonable given the time of year. Maximum usable frequencies over a 3,000km path during daylight have generally been between 14 and 21MHz, although there have been occasional openings up to 24MHz. Sporadic-E remains the main propagation mode on the 10m band.
Next week NOAA predicts that the solar flux index will remain in the 175 to 190 range and geomagnetic conditions are predicted to be mainly settled.
However, the far-side coronal mass ejections we have been seeing suggest we could be in for a rough ride in about a week to ten days. So, this week could be a good time for HF propagation.
And now the VHF and up propagation news from G3YLA and G4BAO
The weather is trying to change to a more summer-like pattern, which means that the main jet stream will be farther north than recently and this will make Sporadic-E harder to find than during the recent strong jet stream pattern over Europe.
For most UK stations, the emphasis on Sporadic-E paths will gradually shift from the typical central Europe and Mediterranean to perhaps Scandinavia and the Baltic states.
The relatively new player this time around will be high pressure which comes and goes during the period but should bring some useful Tropo. In these high-summer days, sea or coastal paths are often good, but paths across hot land do not fare well in summer during the daytime. Concentrate on the night or early morning, especially if it is foggy.
There will be occasions when small lows and fronts edge into the south and west of the British Isles and, in typical summer fashion, may bring a risk of thundery showers. Any local, heavy rain means good conditions for rain scatter on the GHz bands. Meteor scatter again remains in the random category, which usually peaks around the dawn period.
Lastly, a note about aurora which has been kept at armâs length although there have been several periods with a slightly enhanced Kp index. The light summer nights mean that visible auroras are very unlikely but do look out for noctilucent clouds on the northern horizon around midnight.
Noctilucent clouds are thin, wispy clouds that glow with a blue or silvery hue at night when illuminated by sunlight from below the horizon.
The Moon is at minimum declination this coming weekend so peak elevation is low and windows of usage are short. EME path loss is falling as we approach perigee next Thursday the 27th. 144MHz sky noise is high this weekend but falls to low early next week.
And thatâs all from the propagation team this week.
