[Elecraft] K3 key clicks

[Bill]

Bill,

I recently had a similar report that I was clicking and had spurious
radiation up and down the band.  I borrowed a spectrum analyzer and
confirmed that the K3 was indeed producing lots of spurious radiation.  

I contacted Elecraft support and within one day they helped me trouble shoot
the problem down to the component.  In my case Q4 on the LPA board had
failed.  I replaced Q4 and that cured the problem.

I suggest you contact Elecraft support by email (they responded to my email
almost immediately).

Good Luck and 73
