[Elecraft] K2 - NOISY POLLING

[W3FPR - Don Wilhelm]

Chris,

Just a wild guess, but you may want to check the cable between the K2 and
the computer - make certain the cable shield is connected at the K2 end and
is NOT connected at the computer end - if the shield is connected at both
ends, you can get some induced currents on the cable, but I don't know how
it might be coupled into the K2 audio.
