Re: TUNE signal for tuning tuners
CW-KEY is doing exactly the same thing.toggle quoted messageShow quoted text
When transmitting CW, CLK2 is programmed to be at the transmit frequency, CLK0 and CLK1 are shut down,
and a Nano IO pin drives 5v on CW-KEY to unbalance the mixer.

To get less than full power out, you can vary the voltage from 0-5v. TP13 (it looks like TP13 anyway) would be a good place to inject that variable voltage, you'd probably want to use a diode and resistor in line.
