Yeah, just to comment on the hum there on the one station's transmission, it was pretty low level. Nothing totally serious, but a few months ago someone reported to me that I had a bit of hum on my signal and everything's pretty clean with my Asteron power supply and all that. I mean I figure because I've never had any problems. But anyway, I looked around my setup here. I've got a boom mic with a cable that kind of drapes around and eventually gets to the back of the radio. The cable had somehow gotten itself relocated next to a power cord. So I moved that cable a little bit so it was not near the power cord and my hum went away. So lots of potential sources to look at for hum before delving too deep into power supply repairs. Just a suggestion. KI7CEI for those other things.
