[Elecraft] K1 with all options has rising crackling static cleared by transmitting

[Don Wilhelm]

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,
