I thought just the major 4 NY stations were Conus and the rest are on spot beams.
They are. Harrisburg isn't too far from NYC, I am not surprised that the locals work. According to the infamous "database" from DBS, the channel in question is on a different transponder than the others (103, 17). I am in a similar situation - I am "moved" further than this poster - Boston from NW VT. The signals all work, but there are 3 or 4 on a transponder that I only have 77% signal on when it's clear (the others are 85-100) so when it snows hard, they go away when the others stay. The SD of my iffy channels works when the HD doesn't, but it doesn't appear that there is a SD for ch 49.
