I have an antenna tuner and am trying to use it whilst receiving only (i.e. I am not transmitting).
Learning how to use a tuner for receive only has been ‘fun’ but I have learnt that you tune it by listening for the loudest ‘noise’.
One way to finding the loudest noise (whilst tuning) is to watch the noise floor in the spectrum display – but this is somewhat hit and miss.
Is there a way to find a digital readout (in SDRuno) of the average noise floor in the 2MHz band that is being displayed? Similar to the SNR readouts.
