television, single-sideband voice and several other interesting modes. As a Technician class Ham Radio Operator, you can even make international radio contacts via Ham Radio satellites,and actually communicate directly to hams aboard the International Space Station (ISS) using relatively simple and...
A key point is not to overdo the radio operating, or the friends and family will veto any radio activity on future trips. This was not a super-gonzo turbo-charged DXpedition. I just worked in some radio action in between snorkeling and exploring the island. This is referred to as a “...
When the SWL and Amateur Radio hobbies meet by Dan Greenall Many of us who are also amateur radio operators, got their start in the hobby through simply listening to shortwave radio, or perhaps, to stations in the AM or FM broadcast bands. I suppose it is then inevitable that these two ...
I'm trying to install a HAM radio in my 40' Class-A motorhome. It's skinned entirely with fiberglass. I think I have found a mirror antenna mount for the antenna. My concern is about the ground plane requirement to make antenna work. If I can get it to work and install the antenna...
Field Day is a great way to learn about amateur radio. Local Clubs get together (there are over 700,000 amateur radio operators (hams) in the USA) and for 24 hours setup and operate ham radio stations - it is a way of practicing for emergencies and introducing ham radio to people ...

t measure the radiation efficiency but theycanmeasure the power/SWR. Many radio amateurs seem to think that a low SWR means that all the power is being radiated, so you cannot really call the producers of these antennas “Con Artists”, they are merely producing what the radio amateurs say...
This took years for me as I am rarely at the radio in the evenings. But with the solar conditions causing so much difficulty during the afternoon, I have spent some time hunting after sunset. As it turns out, that often yields excellent results on 40 and 20 meters. Posted in Awards, ...
Many SDR receivers, especially those designed for full HF-spectrum use, have needed various filters and preamps between the antenna and the SDR. High-power AM and FM broadcast stations can overload the receiver front-end, so these are filtered out. The characteristics of atmospheric background ...
