[Elecraft] K3 AGC and Apparent Noise and Signal Distortion

[Geoffrey Mackenzie-Kennedy]

Hello Paul,

Do you hear any "raspy" sound when listening to quite strong CW sigs - not 
the sound of real band or thermal noise, but more like the sound of paper 
being torn?

I should not be asking as I do not own a K3, but curiousity is killing this 
cat!

73,
Geoff
