How many truly field expedient ham radios are available? Maybe only 2!
Only two? If you were to ask the military you might get a different answer. Indeed many hams actually use ex-military portable radios, such as the PRC series. Those radios are in a class of their own, but they are often heavy, designed to be carried into the field by fit, strong, young soldiers. But … Continue reading How many truly field expedient ham radios are available? Maybe only 2!

A link to the original article is at the bottom of this post. A "30-minute special" was built to prove the concept actually works. It did work fine … Continue reading An improved tank circuit EFHW coupler
My radio is tiny. So why is my POTA backpack so heavy?
We have mountains in Ontario. We call them mountains, but they are really just small hills. So I have never had to actually hike for miles up steep slopes carrying a backpack with all my radio gear, plus anything else I might need for a mountaintop activation. To all those who operate in this fashion, … Continue reading My radio is tiny. So why is my POTA backpack so heavy?

The POTA PERformer is an adjustable elevated vertical radiating whip with two adjustable elevated radials. In concept … Continue reading Testing and modifying the “POTA PERformer” antenna
Reviving a Webster Band Spanner – a 1950s manual screwdriver antenna
About 20 years ago I was approached by a neighbor who, knowing that I am a ham, asked if I might be interested in looking at some of the old ham junque he had accumulated over many years. He was a fine gentleman, in his golden years, who was no longer active in the hobby. … Continue reading Reviving a Webster Band Spanner – a 1950s manual screwdriver antenna
Matching an EFHW antenna – a third way
There is no doubt about the popularity of the End-Fed Half-Wave antenna. It is used by a very large number of hams, especially during portable operations like POTA, SOTA, WWFF etc. Why is it so popular? The principal reason seems to be ease of deployment. The EFHW requires only a single support and can even … Continue reading Matching an EFHW antenna – a third way
