Check your light bulbs, especially if using CFL or LED. I have had both emitting bad noise. Shutting them off rid my whole station of the issue.

Connecting a 13.8V source to it (one that was plugged into the house power) didn't really change whether the 'buzz' was present or not. The only thing that changed it was either unplugging the offending power supply, or de-energizing that circuit in the house (by tripping the breaker). I guess it's not impossible that the thing was putting off a lot more energy than I thought, and I was picking up a lot of common-mode noise on the cable shield-- a lot more than I thought I would/should. Good ideas though.

And if you have to lie to support a position, that position is not worth supporting. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
