Hi,
I have a uBitX to build over the Christmas period. I will be using the KD8CEC firmware and Nextion 2.8" screen
Is there an easy way of altering the output power, short of dropping the supply voltage ? If I could make this easily adjustable....

I like to run QRP CW so that means no more than 5 watts output.
Any ideas appreciated to save me re-inventing the wheel.

Thanks,

Reg

Please observe the schematic of the radio board.

Resistor RV1  is there to serve that function.  

NOTE; if you turn it down (clockwise, yes its odd) for 5W on 80M
you will get less power on successive bands.

There is also another approach by John, VK2ETA, who tried to control SSB and CW power output via software/firmware by changing the clock frequency of the raduino (40 Mhz IF).
I do not understand it fully, but details can be found here.

I would suggest to just get a non-inductive potentiometer,  put it on the panel, and run tiny coax to it so you have a panel mounted drive controller.
