Bill,
The AGC Threshold has a lot to do with it. Check out the "Noisy K3"
article on my website www.w3fpr.com. Set it to suit the noise at your
QTH, there is no 'one size to fit all'.

I have been using my K3/P3 since new in early 2013. Initially, I had a
devil of a time getting the RX audio to sound pleasing. Understand -
that is pleasing to me. There was always a high percentage of background
white noise.
Eventually, after a lot of experimentation, I settled on various EQ,
AGC, ATT, RF Gain etc. All this was to make it comfortable for long-term
armchair copy on 40, 75, and 160 meters. I also bought a pair of
Behringer MS40 speakers to improve things. All told, I was relatively
pleased with the results - - - until...... I bought an Icom 7300.
The 7300 is quiet. Nearly zero background noise - signals just jump out.
During the daytime it is close to that of 2-meter FM. Understand that my
QTH has nearly zero noise.
Where am I going with this? Simple - I am looking for suggestions on
eliminating the K3's white noise problem. Please do not email, as I am
sure I am not the only K3 user similarly interested. Sharing would be
great.
Thanks,
Bill W2BLC K-Line
