No, if you have a snowy picture, it's probably in the cabling.can a signal booster/amplifier be used on the standard def side of a dual tuner sat receiver
Love your advice on the output channel. Spot on and I completely forgot about that change. Thanks for refreshing my memory. Boy, people on this forum are smart . Love the advice here.If you are talking about the modulated output of a 722 try changing the output channel to something lower than 37. All of the channels above that are full of cell phone frequencies now and can create interference. Of course don't forget to change the receiving TV to the appropriate channel.
