| I have interference in the form of horizontal lines across the entire band (seen on IC-7300 waterfall). These lines generate at equal intervals like a pulse but very straight horizontally. It is coming from a source outside the shack. I ran the radio on battery and shut the power off to the house. Interference remains. Originally, it just appeared and lasted a few weeks, then disappeared overnight for several weeks, and now has returned. I thought it was a power line issue. Power company "says" they checked outside poles and found no issues. I'm lost on this since it has come, gone, and reappeared at several week intervals. Any ideas???? |
