Hi,

I wish I could set it higher than 008. I am also in a relatively quiet location but on 20m with an AGC threshold of 008 my atmospheric noise is normally above the AGC threshold. So when I want comfortable listening I back off the RF gain until the S-meter shows about S4 or so. Not a big problem, but I would prefer that the AGC threshold could go higher. Having it stored per-band, too, would be really, really nice and it makes sense.

I just thought of something that might help those confused by the AGC
Threshold setting.
One other way to look at the required AGC Threshold level is to think of
it as an S-meter level
If your noise is S-1 or lower (on the K3's S-meter), you can set the
Threshold to 002 or higher and all may be well
OTOH, if you have an S-7 noise level indicated, the AGC Threshold should
be set to 008 or higher.
