Today the WRC-12 Plenary meeting went over the list of future Agenda Items (for WRC-15 and WRC-18) in second reading. The meeting agreed that WRC-15 will consider a possible new secondary amateur all
Hi Pete, You have the right idea, but instead of a 1 mh choke, you should use a few turns of #18 insulated wire on a small ferrite core. The required number of turns depends on the ferrite core you h

We really don't need beacons on 160, the reverse beacon network provides good coverage. We just need stations on the air to be detected. http://www.reversebeacon.net The W3AO Field Day will have thre

If ferrite isolators or beads have been determined to improve the shield performance of a coaxial cable in your hamshack, something is fundamentally wrong either with the cable (but most likely the c
Mike, I use BNC connectors extensively (almost exclusively) in the receive paths in my station, perhaps one hundred or more. They have their own shield integrity issues, there's no silver bullet with
Hi Mike, It was good to meet you for the first time this year in Dayton, I enjoyed our brief conversation in the flea market. I've had exactly the same experience with off brand BNC cables and connec

I'm liking my current forcing, 1/4 wavelength and 3/4 wavelength coaxial baluns more and more! 73 Frank W3LPL choke balun reduces common mode. Outside of that, the air core choke can air-core chokes.
Hi Rick, A monoband current forcing balun doesn't require as much coax as you might think. The 1/4 wavelength of coax would probably be needed anyway, so the only "extra" length is the 3/4 wavelength
Hi Tom, I'm sure you're correct that a current forcing balun performs poorly when driving an unbalanced load. This shouldn't be an issue when using it at the balanced feedpoint of a properly construc
A time domain reflectometer (TDR) allows you to check all major components (feedline, transformer antenna and termination) of your Beverage antenna from the comfort of your hamshack. 73 Frank W3LPL -
