Thanks Don. I just realized that I can do some quick experiments to get my answer using an XG2's s3/s9 capability and noting audio level increase with AGC Off and then with AGC On and reducing RF Gain until same audio increase is accomplished.
An aside to KE7X and W4TV: I too wish we could try experimental firmware that significantly raised the max AGC THR value. And to K6LL: Yes, I too fear loss of weaker signals 73, Barry N1EU On Thu, Dec 9, 2010 at 3:00 PM, Don Wilhelm <[email protected]> wrote: > Barry, > > Without doing any measurements it may be difficult to say precisely, and I > would think there would be a bit of difference from one K3 to another. > > However, there is a quick and easy way to accomplish that - note that the > S-meter increases as the RF gain is reduced.
