Remove spectrum covered by TNF from AGC and S meter

KD0RC

I don't know how feasible this is, but I would like to see a signal that is removed by the TNF not be part of the AGC loop, and not show in the S-meter. Occasionally, there is a horribly strong carrier that I can remove with the TNF, but it knocks down the gain of the rest of the passband and gives an erroneous S-meter reading for the desired signal.

Thanks for your consideration & 73,

Not much help, but a little explanation. The TNF works in the audio chain, after all the rf processing (S-meter, agc,etc). it’s not the way I want it to work either, seems to me the TNF should reduce the level in the pan adapter, at the rf level of processing. I think that would also accomplish what you want.
