Long Delayed Echoes  

Strange ducting in our atmosphere? An alien repeater in outer space? No one really knows what causes this spooky phenomenon.

Restoring Old Radios  

We end the year with a fond remembrance of rigs gone by, and a discussion of how to bring them back to life.

Antenna System Troubleshooting  

How to track down and fix those annoying antenna problems.

Yagi Antennas  

A discussion of how these venerable antennas really work, with a nod to Mr Uda!

Stealth Antennas  

Sometimes the best antenna is the "least" antenna.

Anderson PowerPoles and Antenna Polarization  

All about those red and black connectors (they come in other colors, too) and a discussion of antenna polarization.

HF Mobile Antennas  

Operating HF mobile presents several unique challenges, starting with the antenna.

Bits vs Baud  

When it comes to digital communications, many amateurs believe that bits and baud are the same, but they're not!

Coping with the Solar Minimum  

We're on the downhill slide to the solar minimum, but that doesn't mean the end of Amateur Radio enjoyment. Even at the very bottom of the cycle there is still plenty to do, and plenty of ways to do it!

Coaxial Connectors  

They may seem simple, but there is much more to the common coaxial cable connector than you may think!

Software Defined Radio  

What is software defined radio? Well, it depends on how you "define" it.

Standing Wave Ratio  

The Doctor addresses the misconceptions surrounding SWR - Standing Wave Ratio.

Magnetic Loop Antennas  

Are magnetic loop antennas really magnetic? And how can they be so small, yet work so well?

HF Propagation  

The key to getting the most from Amateur Radio on the HF bands is to understand the concept of "propagation." HF propagation can be fickle at times, and often downright spooky!

Are Linear Amplifiers Really Worthwhile?  

Adding a linear amplifier to your station can be a substantial investment. Is the benefit worth the cost?


What does it really mean to have a good "ground" at your Amateur Radio station? Does every station have to be grounded? If not, why not?

All About Baluns  

Baluns have been fixtures in Amateur Radio antenna systems for decades, but what are they? Does every antenna need one?

May 19 - Hunting Down Interference  

The Doctor discusses the wide variety of interference sources you'll encounter inside and outside your home, and offers tips on how to deal with them.

May 5 - Open Wire Feed Lines  

Open wire feed lines are touted as being superior to coaxial cable. But is that true in all applications? Listen and find out!

April 21 - Does CW Really Get Through When Nothing Else Can?  

Is it true that CW can get through when nothing else can? The Doctor separates the myth from the reality.
