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 [email protected] ----- Original Message ----- From: "AC7JW" <[email protected]> To: <[email protected]> Sent: Wednesday, December 09, 2009 9:40 PM Subject: Re: [Elecraft] K3: Relay noise?
