Hi Rick,

Have you seen the following?

Power can be detected with this circuit and displayed in the SDR program.

However, a statement needs to be added to the firmware to read the voltage from the low-speed ADC and send it according to the protocol.

I have experimented with firmware modifications before. see below. (Radioberry_PreAmp_Power_experiment.pdf)

Many thanks, Yado-san!

I see in the pdf the modifications. 

I think I can use any kind of ADC chip, not only the (in Argentina) unobtainable Max 11613.

Very appreciated contribution!
