Guy's analysis seems to identify the key point. You can definitely get better reception under noisy conditions by going into "SX-101 mode," turning the AF gain all the way up and riding the RF gain with your left hand. This reduces the AGC effect, possibly defeating it altogether, depending on where the RF gain is set.
As Don points out, the first step is to go to the Config menu, and set slope and threshold (0 for slope and 15 for threshold minimizes the noise enhancement of AGC). When that isn't enough, you can leave AGC on and tune as described above, or turn AGC off altogether; this gives good results, but requires even more constant cranking of the RF gain. I have noise not only on 80 and 160, but often on all bands. Sometimes when using this technique I can find a setting for RF gain that is right below some sort of threshold where the noise suddenly jumps into my ears. Re-shaping the AGC in this way almost always improves the K3's signal/noise audio as I perceive it when digging for weak signals. Perhaps some manufacturer, or maybe all manufacturers, will soon figure out a way to handle this automatically.
