After shutting off all the various circuits in my home, I discovered that the noise is actually coming from the TV in our living room. The existing dimmer switches are made by Lutron, and are not making much noise after all. Whenever I plug something into one of the TV's inputs (cable, composi

I made a few recordings of some noise that I hear on 40m tonight. The .wav files can be downloaded at the address below. I have no idea what's causing this noise, or how to filter it out. Is this the type of noise that the KDSP2 or KNB2 could remove? Thanks, Zac KD5IEF http://homepage.mac.co
