Robin,
I tried to reply to your earlier question, but since you posted to
nabble only instead of the Elecraft reflector, I was not able to
respond. I do not subscribe to nabble and my response was rejected.
Post to the Elecraft reflector to avoid that problem.
Such crackling static is usually from a local noise source rather than a
problem in the K1 (or any other transceiver). Yes, it will be muted
during transmit, and if the noise is strong enough it will de-sense the
receiver.
If the noise is heard when you are connected to a dummy load, then the
problem is in the K1, but if it only occurs with an antenna connected,
then it is a local noise source that is coming from your antenna.
73,
