I've followed this thread concerning a QSK clicking noise through all comments, as well as other similar threads on the list, but it doesn't appear as if anyone ever came to a firm conclusion as to origin of this clicking noise. As others have stated, I can hear a very faint mechanical clicking that follows my code when using QSK. It sounds like it's coming from the KPA100 region, but I can't tell for sure.
Did anyone ever come to a conclusion, or receive any information from Elecraft?

Thanks-

Is there a mechanical relay that follows keying? I've had my K3 for nearly a
year and didn't notice any relay noise until lately. I know the antenna TR
is done by pin diodes but I can now hear the faint click of a small relay
that wasn't there before. I'm using ver. 2.8
