Help - kit-projects AGC module V6 - Smeter voltage is too low #ubitx #smeter #v6


 

The output signal "S" for use as "S-meter" is honestly too low:
the variation goes from few mV to a maximum of 1.7 / 1.8 V (the max  with S 9+30dB (-43dBm in antenna) rf signal level), this severely limits the possibility of use through the A7 input without changing the ATmega328 Vref value reference, for have a minim of accuracy in low signals level.

I would like to know if the voltage value read on pin S of the kit-projects AGC module is correct or is there some way to have higher output levels?

Thank you to all !
