Re: SNR meter, bandwidth and gain adjustment for transverters

Mark Cayton

Per the info on Simon's page explaining the operation of the S-meter, "[The signal level] is the peak spectrum FFT bin (output value) which is within the current filter."

That page is found here:

Simon explains it clearly. There is no correlation of peak FFT bin value to filter bandwidth (or AGC level, or any other consideration), nor should there be. Any modern SDR-based S-meter that changes its reading based on filter bandwidth is doing it wrong.

I've said it before: Simon got it right, many others are getting it wrong.
