[Elecraft] Noisy K3 receiver

[Steve Ellington]

Ed
I agree. I have no idea what these people are talking about.
I've had a lot of radios. My last was the IC-7800 which sat beside the K3 
for a month until I sold it. I can't imagine what this noise is that people 
think they hear. Perhaps a .wav file from someone would be helpful.
