24.1 dropping out while watching on my Panny tonight

Was wondering if anyone else was having this problem. All of my HD channels were working fine but 24.1. For some reason when that channel was on it would drop out for just a second and come back. I called a friend that lived a few miles down the road and his was not doing it. He has a Sony but mine is the Panny ED 37 Did anyone else have this problem tonight. THanks for any input
