Oh well,I don't like to argue anybody or disagree anybody but I was at the contest as well and and I could easily separate CW stations that were off between 100 200 Hz with my K3 using the 400Hz roofer and the DSP set to 100Hz and also moving the Shift acordingly,.no problem at all with the selectivity and also I used the great help of the APF as well. If it has to be with the AGC or not,these are my settings that has been working for me in any case: AGC DCY.....SoFt AGC HLD.....0.05 AGC PLS.....OFF AGC SLP.....0.07 AGC THR.....007 AGC-F.........080 AGC-S.........020 To help in the RX filtering I have set my RX EQ this way: 0.05 at minus 16 0.10 at minus 16 0.20 at minus +0 0.40 at +3 0.80 at +3 1.60 at minus 16 2.40 at minus 16 3.20 at minus 16 PITCH at 400 (I like to hear better at low pitch) With these settings my K3 is super selective and have no ringing noise even at 50Hz DSP bandwiith. In those conditions I can work any contest no matter how crowded it will be. AD4C

I have just started to try and optimize the AGC settings for large signal conditions and so far, I'm not anywhere close yet. If I can find anything useful, I will post it here. I certainly do hope others who may already have optimized their K3 AGC for large signal contest, will also post their information. 161, Tom - W4BQF -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Bob Henderson Sent: Sunday, December 05, 2010 4:39 AM To: elecraft@mailman.qth.net Subject: [Elecraft] Recommended AGC settings for separation of signals in CW pile-ups CQ WW CW is now over. We used K3s at P3F this year. While performance was generally considered good, some questions were raised over the effectiveness of the K3 in separating signals in large piles. Similar concerns appear to have surfaced from other users including the guys at 9L5VT and C6ATA. Anecdotal evidence suggests the old TS930 and TS850 performed better in such circumstances. I suspect the AGC systems of the K3s used had not optimised. Has collective experience of the K3 contesting community derived optimum settings for the K3 AGC system in this kind of situation?
