I was wanting to know where the recieve potentiometer is located on the schematic. I would like to try to squeeze a little more recieve out if possible.
There are no potentiometers on the Digirig Mobile 1.9. There is an attenuator jumper to take the RX sensitivity down 20dB, not useful in your case.
I adjust my RX sensitivity in the OS sound software.
