Is anyone having trouble lately getting a picture on digital CH 9 (9-1) in Washington, D.C.?? The last couple of nights, I'm getting no picture at all. I tested signal strength (DTC-100) and it's coming in at 94. I get extremely choppy sound, like it's trying to come in, but no picture at all. I'm not having those problems on digital 4, 5, or 26, even though their signals are weaker.
