I've started having some issues with a few channels over the past week (139, 176, 239, 350, 402) with varying degrees of pixelation and audip dropouts. I've typically had a solid installation with 40-50 on all 129 transponders, and I know that is atypical for the 129 location... but on the transponders these channels are located I'm finding that sometimes they dip down to 25 and are no higher than 37 in most cases when I'm seeing problems. Other channels on 129, on other transponders, haven't exhibited the same symptoms. The reason I'm posting... is that I suddenly connected some dots in my head... there has been a major fire burning in eastern NC for a couple of weeks now... and just this past week the local news started talking about how Raleigh air quality has gone down and we can see some smoke drifting westward from the big fire in our area now. So it got me to thinking... I wonder if this has now started to interfere with my 129 reception. 110/119 were always high so it would take a lot to knock them down... but with 129 being lower, maybe this is what is happening to me now. Anyone else in central or eastern NC have a dish pointed at the 129 location and having increased problems with some HD channels lately please join in and let me know if I'm onto something. IF correct, then I'm guessing I have to live with it until the smoke literally clears.
