It isn't so much that the K3/K3S has "gain", but that the factory

Great advice. Mine, from one who has done this unsuccessfully, and then
with advice, done it successfully, GO SLOW. This means small changes to
one parameter and some listening time before another change. The
changes to the various AGC parameters will have subtle effects, not all

Yes, the AGC settings do help a lot. The K3/K3S has enough gain that
often the AGC is activated on the atmospheric noise in the band.
However, I think your chosen AGC settings are a bit extreme for general
use, but if your ears tell you it is good for you, then keep those

"Too much noise" might mean the AGC threshold is low. One way to adjust it is
to set it so that AGC does not activate on band noise (of course it's different

possible except protect my ears.

Hi Ron,
That review of the K3 audio by Rob Sherwood was on a very early K3. We quickly
addressed the high freq harmonic issues (most of which were above 4-5 kHz and
were more than 50-60 dB down) with a K3 DSP board revision that included a
change to a beefier low ESR power supply filter choke

If your problem is more related to "band noise", you may want to

To my ears, the K3/K3S sounds a bit 'noisy' with the default AGC
settings. Increasing the Threshold and decreasing the slope may help.
