- Hi, just recently I started giving my TV interference while on the 20M band. When I transmit running 500 or more watts, the screen will black out until I am done. I have cable TV, and the TV is a 32"

- John, have you carefully checked all your TV cabling, particularly the F connectors and splitters? I've had open shields that produced this sort of problem. 73, Pete N4ZR The World Contest Station Da

- I had a similar problem with a 10m setup in the 90's. I tried all sorts of things, but what worked for me was lining the cabinet with metal foil and grounding the TV. Kurt __________________________

- Does it bother all channels, or just some specific ones? What modes are you running? You say you just recently started bothering the set so I'm assuming that you ran for some time without RFI. I doub

- Thanks for all the suggestions. I will be trying solutions tomorrow during the day. A couple had questions, first off it is all modes, and I have never had a problem in 10 years. I asked the neighbor

- If you don't find anything in the home, you could check out at the pole by listening on 145.25 which I believe is Ch 18's audio sub carrier. If it's really strong even a 5W HT will blank out that cha

- Take an HT listening on 145.25 around the house. That is Ch 18's audio subcarrier "IIRC) Any leak would show on the s-meter although it may not break the squelch. 73 Roger (K8RI) ____________________

- 145.25 is the CATV Ch 18 (Ch E) NTSC video carrier frequency, and on an (FM) HT it will sound pretty much like unmodulated dead air. The audio for that is 4.5 MHz higher (so out of the 2m band). It's
