Thanks Steve. It's sure strange that I get the same click whether I run 1 W, or 100 W. I could understand some sort of residual magnetic effect (for lack of a better term) causing some mechanical movement to create the noise if it was only present while running high power, in which case high currents are present, and thus the potential for a powerful magnetic field. But at 1 watt- there is something else going on. In any case, I don't think it's a problem- just an annoyance.

I used some plastic tubing stuck in one ear trying to track it down. I narrowed it down to one relay but it's been at least 6 months ago and I can't recall which one made the noise. I had suggestions to check for loose ferrite chokes along the high current DC line but that wasn't the source. If I happen to remember which relay it was, I'll post it here. 73 Steve N4LQ [hidden email] <http://n2.nabble.com/user/SendEmail.jtp?type=node&node=4143590&i=0> ----- Original Message ----- From: "AC7JW" <[hidden email] <http://n2.nabble.com/user/SendEmail.jtp?type=node&node=4143590&i=1> > To: <[hidden email] <http://n2.nabble.com/user/SendEmail.jtp?type=node&node=4143590&i=2> > Sent: Wednesday, December 09, 2009 9:40 PM Subject: Re: [Elecraft] K3: Relay noise? > > 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.
