Does anyone know of any tweaking to correct this problem?: On my cable system, Game Show Network (GSN) is broadcast on analog Channel 96. I keep getting squiggly lines on this station only. When I pull out the cable input wire while watching channel 96 only, I can hear a local radio station being broadcast. All my other cable stations are perfectly fine. The cable company is not providing much help. I pay $100 a month for COMCAST and this picture quality is unacceptable! Does anyone have any ideas to correct this problem? Is there a type of filter I could buy to filter out the radio station and improve my reception on this channel? I would greatly appreciate any suggestions or help.
