AGC settings and AF gain interact. With no signal you may have lots or little audio. Also, full audio can be at 20% of 50% gain. When looking at the spectrum of a CW signal one clearly see the third and the fifth harmonics. Not sure whether they are real or artifacts of a sound card but K3 sou

Audio response seems to be a difficult area for Elecraft. SSB from the K2 often received poor reports because of the excessive LF response in the TX audio stages. It could be cured by reducing coupling capacitor values. The K3 RX audio appears to need the opposite approach. Stewart G3RXQ On Mon

I have very sensitive in-ear monitors. The K3 (and the Orion, and possibly other radios) has significant hiss. I inserted an attenuator and knocked the hiss down below my ability to detect it. There is plenty of audio range remaining. You may find 10 to 20 dB will help. _

Hi all, In my view the only "problem" with the K3 being "hissy" is the AGC threshold. On 20m and below even with AGC threshold set to the maximum (008), just the atmospheric noise is at or above the threshold and this is indeed tiring to listen to. I solve the problem by turning down the RF

Hi Maarten, I tend to agree with your observations. If you live in a noisy environment like I do, the K3 RX can be quite "restless" and listening fatigue comes in easy. I played with the AGC setting a while ago and came up with the following settings in the CONFIG menu: AGC SLP 008, AGC THR 00
