If your’re interested in building a clone of the Alphamatch, a.k.a the “magnetic longwire balun” that was discussed at the October 4th, 2016 meeting, here are some links you might find helpful. I’ve added a link to my hand-out from Tech Net on the Hill!
The End-Fed Half-Wave tuner we built at yesterday’s lecture and lab really does work! I disconnected the tuner from my base rig and cut some wires to the “30 meter” length printed on the PCB. The half-wave wire was tied to an old railroad spike that I threw up into a pecan tree. The counterpoise is sort of lying on the back deck.
