    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.


    You might try using a signal generator attached to a wire to create a steady carrier. It might be easier to tune for a peak on a steady signal than the noise floor. I haven’t tried it so I don’t know how it will work. Just another approach.
