Yes, Nick, that's the spot....between where you have your HPF and the relays. Nice short leads for the RF. I'll upload the new board later today. You would plug it in with components towards C210 and could install the 1"x1" board with components down, board parallel to the uBITX board, and over R43.? It also provides points to be wired over to a RF Gain potentiometer.
