[RFI] ARRL to FCC...

[Dale J.]

Once when I had access to the TV, I tried one of those outlet strips with filtering and it made no difference.  I would have liked to spend a couple hours troubleshooting his house, but I felt too much like imposing on them.  I kind of have the same feeling about the stuff radiating over the power line and the cable TV coax.  Again it takes time to work around this by disconnecting and checking etc.  It would be ideal if just me and Steve the household head were there alone and had the time I'm sure he wouldn't mind, but the whole family is around when they aren't working, so it's not easy.  I would like to try a better line filter on the TV.  I don't have a lot of confidence in that outlet strip filtering.  And of course no cobbled up thing hanging off their TV is acceptable, it would have to be very professional, like in a NEMA box with the proper grounded outlets etc.  I wouldn't want to have a fire started with something unsafe.  All these things have to be considered when working with someone else's house and equipment.

Some have speculated that the noise comes directly from the TV, and this could be true, but I still tend to think in terms of noise coming out the AC mains and possibly also being radiated by the shield of the incoming coaxial feed line.
