The QRPer Board

Someone gave me one of their early 3-element yagis and the control box awhile ago with one bad element. Tape is screwed up in one of the elements. I think because they’re no longer going to support hams I’ll make it into a rotatable dipole and use the rest for spare parts.

Looks good. Do you know if there's one for a TR-35?

Guess I'll check 6 for TEP.

Hope to have a QRP to QRP QSO with you at some point while you're operating POTA. I just started activating a few parks; mostly a hunter though.

https://k7mem.com/Ant_End_Fed.html#Not_Random_Multi Andrew do you actually have experience with a 29 ft end fed antenna? I do, and it works pretty well on 40-10 with a 9:1 transformer. no, didn't try it; but the fact that it's shorter than 1/4 wave on 40 raises some doubt about its radiation effici...

Whenever I use mine it works fine. Certainly not a dummy load.

Just wanted to introduce myself.

AA5ET, Marco in Albuquerque in the Land of Enchantment, and glad to be here.

For more info you can look up my call on QRZ.

I built and tested an EFRW / 9:1 Unun antenna with 29.5 ft (9m) radiator and single 17 ft (5.2m) counterpoise. With Elecraft KX2 internal tuner, I can reliably tune 60m to 10m bands. I am using it for QRP CW field (POTA) operations, and have had a respectable number of contacts. Deploying it is ver...
