[Elecraft] K3S audio board for K3 upgrade?

[Gene Gabry]

This has been an interesting thread to which I have experimented a bit more
and found the AGC setting recommendations from a couple of posters to be
very valuable, and Eric's suggestions on BW settings to be a nice compliment
to play with. Although, my ears still like a little HF, I like the sound of
a BW from 100hz to 2.7khz for SSB and usually the 500hz filter set to 300hz
with DSP. I now have AGC THR set to max and AGC SLP set to 0. I also set RX
EQ to flat and use hi/lo cut when needed. Really cuts down on the high
frequency hash I get from this qth. I leave the AGC settings the same for
SSB and CW and play with BW and cut between the two modes, depending on
conditions. 

I've never ever put any stock into any manufacturers built in speakers. They
are there cause they have to be :) For the K3S I use a combination of a pair
of Polk Audio 5 1/4" book shelf speakers (60hz-24kz) and Pyle Pro 3" mini
cube speakers (90hz -18khz), per channel, and the sound is crisp and clear
audio. And, both speaker sets are black to match the K3S and all together
for all 4 speakers cost was $75.00 and change. 

The AGC settings were a big game changer to these old ears.

Yes, excellent AF response, very nice for recording, but massive overkill. I
have a pair as well. BUT -- they are also RFI dogs. Keying a 5W 2M talkie
across the room will cause their woofers to move enough that you'll clearly
see it, and they're also susceptible at some HF frequencies.
