Does anyone use a receive antenna with the QCX? How do you manage T/R switching? Do you have a preamp? Thanks Richard - NS3C

Assume you are referring to LPF coils. Can you post closeup photo of that area of the board. Are you sure all items installed in correct position?

I await other comments, but at those very high resistances, it may well just be that you really should be careful to keep your fingers away from everything. I would hold T1 down in a fixture and try t

Hans, I want a QCX+ for 160 meters. The lower frequency should work fine with the QCX+ design. 160 meters is a great band for CW and antennas are not too hard to make work there. Dave. N2SN

The purpose of this mod is to give QCX access to a receive-only antenna via the 50 Watt PA kit. This can be added to a functioning PA or the kit can be built as a T/R switch without the amplifier circ

okay forgive me for talking to myself here! of course I should be focusing on L3 (the PA end). removing about 6 turns on L3 and 3 turns on L2 has the power up to 4 watts. been a few years since I chec
