Hey Zac, That sounds very similar to what my plasma TV emits. I have my window line running along the outside wall where the TV is mounted and when it is on, I can hear it very plainly. The tone fluctuates with changes with the picture. I've also noticed that it peaks at certain frequencies as well.
I was able to detect it as well when operating portable in my yard 100 ft away with a separate antenna in a tree. So I know it's not just in the power line. It is considerably attenuated out there - but there none the less. BTW - I have a 50" Panasonic Plasma - beautiful picture and a great RF generator. 73, Dave W8FGU > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:elecraft- > [EMAIL PROTECTED] On Behalf Of Zac Brown > Sent: Thursday, September 06, 2007 11:48 PM > To: Elecraft reflector > Subject: [Elecraft] Help with noise on 40m > > I made a few recordings of some noise that I hear on 40m tonight.
