When I turn on my TV i get 5 S units of noise on 10 meters (28 MHz).
I have cable TV. When I disconnect the cable from the TV the noise stops. Somehow the noise is being generated from TV (when it's on) and sent through the cable lined which is effecting my receive on my radio. I was thinking a high pass filter where the cable goes into the TV. Anyone know if this would work? If not, then what might work? Thanks in advance, Scott |

I know of an elderly couple who had a similar experience recently. They had
a TV putting out RF and they too were on Cable. The RF would radiate from the cable into other TVs, be they connected to the cable also or not and other appliances which were in some way, receivers.... VCRs, etc. The cable company was called in to investigate and they traced it down to the tuner of the offending TV set. As soon as that set was turned off, all RF interference ceased. Not sure what they ended up doing with the offending set. To my knowledge, they were not told to try to filter it or anything else, so I can't say what the conclusion was.

The TV is brand new. I already know the noise is coming from the TV.
The question was, weather a high pass filter would suppress the noise generated from the TV. Anyone else ever have this problem?

Try a brute force AC line filter. These 'state of the art' TVs mostly use
switching power supplies. Puts out an amazing amount of trash. Dan/W4NTI "Scott" wrote in message om... The TV is brand new. I already know the noise is coming from the TV.

And make the RF cable into a choke (wind around ferrite core or such) at the set connection, to minimize noise conducted over the outer braid of the coax. |
