Makes sense. It does seem rather touchy and the effect on signal strength of the received signal is more like an on/off switch than a range, like you might expect. Anyway, it works and I am now comfortable proceeding with the bias adjustment
and band specific drive adjustment for the PA. Let me know if there is anything that I should be looking out for while I go through the process.?

To be clear, both the receiver and the transmitter use that mixer.? It translates the signal from the 40MHz IF frequency to the operating frequency in both directions.
