It sounds as if you were using the antenna coupler. Perhaps it was one of the relays there that was clicking. It may be that the edge of a band in the auto tuner was bridged by the transmit and receive frequencies in split mode and the antenna coupler was changing settings with the keying. I don't know for sure so some comment from one of the gurus at Elecraft would be useful. Willis 'Cookie' Cooke K5EWJ & Trustee N5BPS, USS Cavalla, USS Stewart

Apologies if this has been covered before. I have looked but found no definitive answer. This morning, after getting up early to catch the greyline for HK0NA on 80M, (which was successful, 80M CW & 40M SSB bagged with my 100W and bit of wire.) I noticed a clicking from the rear left (I think) of my K3 whenever I TX'd. QSK semi instead of fully reduced it and it was not evident on on Test mode. I am assuming this is connected with the PIN diodes. It was only evident on 80M. SWR was 1:1 I removed all leads suspecting RFI but no change. The clicking gradually reduced over time... wierd I did not notice this 2 weeks ago when I last used 80M CW. Any suggestions ? I only ask because I leave for Bhutan in 4 days and I'm taking it with me for a few days operating and hope its not a pre-courser of something horrible.
