Mine is currently set at AGC THR 15 and SLP 15 (for CW). I'm still playing with SLP, tending to set it higher.
The reason for these settings is I want to be able to hear variation in signal level up to about s-8/9, but not much above that. These settings do require occasional adjustment of the AF GAIN between the strongest and weakest signals, but not much. It depends on one's own comfortable hearing range (plus headphones, speaker acoustics, resonances, perceived amplitude of different CW tones, etc.) But I don't get the point of THR 20 SLP 0. I assume that is pretty much the same as just turning off the AGC. Prior to the recent extension of the THL adjustment I would often turn the AGC off and live with distortion at AF LIM = 20. (I also worried about the AF amplifier stages which someone claimed could be subject to damage when the AGC was off.) I think the K3 sounds a lot better since the latest improvements. But that may be a subjective judgement on my part, or due to propagation, etc. But it sure sounds great to me... 73, Drew AF2Z On Wed, 23 May 2012 12:40:01 +0000, Brian/K3KO wrote: >Have you tried these settings?
