Re: [Elecraft] K3S RF/SQL Adjustment
Adjusting the AGC threshold and slope on my K3 to my liking made all the difference for me. I did the same on the KX3 and KX2, as well.

Mike and Brett, Go to my webpage www.w3fpr.com and scroll the left column to the "Noisy K3" article for assistance in adjusting the AGC Threshold and slope. 73, Don W3FPR On 2/17/2021 1:57 PM, NJMike wrote: Brett, I am new to the K3S.

Re: [Elecraft] K3S RF/SQL Adjustment
Mike . . . All rigs are "noisy" if you run the RF gain full bore. Experiment with backing off the RF gain and increasing the AF gain (if needed) until a good signal-to-noise ratio is attained by your ears. This applies to both CW and SSB. It will also be helpful if you put the AGC in "fast" mode. Finally, ignore the S-meter. It will only confuse you and is needed only when comparing two or more incoming signals. It has nothing to do with optimizing reception. 73, Kent K9ZTV On 2/17/2021 12:57 PM, NJMike wrote: Brett, I am new to the K3S. I set mine according to the Fred Cady book.

Brett, I am new to the K3S. I set mine according to the Fred Cady book. Mine are slightly different from yours. But I don't have a good understanding of how the settings affect the performance. Sometimes I think the rig is very noisy, even when connected to a dummy load. I am interested in the advice you get !

[Elecraft] K3S RF/SQL Adjustment
I'll admit I just don't know how best to adjust my K3S RK/SQL knob. I have AGC-S on, filters wide open at 2.8, and have set: AGC DCY nor AGC HLD 0.00 AGC PLS nor AGC SLP 012 AGC THR 008 AGC-F 120 AGC-S 020 On 14MHz CW Mode, where I see/hear CW no signal on my P3, with RF/SQL rotated full ClockWise, S-Meter is solid 3 flashing 4-5. Rotating AF clockwise, from full Counter-ClockWise off, it's pretty noisy at about 9 o'clock. I'd appreciate some advice and learning! How I got this far without figuring this out [shaking head]...
