Don, I tried your settings and wow. I love the radio. I am not sure it is working well. I am on 75 and what a difference. I do have to turn up the audio a bit because signals are fading, but at least the static noise from the radio is greatly reduced and it does behave more like the venerable K2 which I still have and love.

At all settings the AGC will do its job, but if the settings are agressive, when there is no strong signal, the receiver goes to full gain and any noise becomes loud - the K3 will try to make the noise as loud as the signal you were previously listening to. I personally think the default AGC settings are too agressive, but that is only my opinion - I like my K2 AGC (despite Wayne's preference for the default settings). 73, Don W3FPR Bill K9YEQ wrote: > Don & all, > > I was also besieged with noise.
