[Elecraft] QSK clicking on Tx...

[WILLIS COOKE]

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.

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.
