K1 with all options has rising crackling static cleared by transmitting

k1-4 user
Hello group

I
My K1-4 with 17m worked great on FD with > 95% call to contact.
The only annoying thing is a crackling static that starts slowly but crescendos quickly, is strong in strength, and is quieted by transmitting or by pushing the menu button or selection of the next NB level including off.
Is distinguished easily from atmospheric qrn.
In normal active operation the t-r mutes the noise and more than slightly desensitizes the receiver and cuts the static back until it cycles up again.

Any thoughts are appreciated

Robin

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.
