Thanks guys for the input. I had an off list conversation with Lyle and got my answer, Wayne was included too.
The scenario was the morning 75M 'old guy' net. During the lulls, there was a ~15 db above the -110 db noise floor signal (I LOVE the P3!). Auto notch would not take it completely out until I lowered AGC THR to 7 (from 16). I restarted, cycled through auto and manual notch, no joy with auto until I dropped the THR. If I understand it correctly, as you raise THR and/or SLP, it gets harder for the auto notch to remove weaker signals (which this apparently is). So now my goal is to find a reasonable compromise or define two macros to make simple and quick changes, one for ragchewing and another for DXing. But first I want to better understand what THR and SLP do and how they interact. (NOT tonight!) Thanks again all (grazie e ciao!), Rick wa6nhc -----Original Message----- From: Pierfrancesco Caci It nicely notches away a broadcasting carrier at 7200 kHz here, tried with THR 12, 16 and 20.
