Just a couple of tidbits. One, Most if not all feeds are coming thru the airwaves to an antenna near you. Dish direct cable over the air comes thru an antenna. It is just how it is. So the best way to determine if it is on your end is to reseat or reset your antenna connections. I dont know if it is all you or all them or all Romulans...
. I just dont know.
I do know that if my antenna (over the air) is just a little bit off (shifted to a different angle than Bogus Basin Ski Resort), my feed gets really screwey. The digital feed becomes fragmented and some of the feed is weaker or not working at all. I have some weather that came thru and made some stuff a bit more difficult to determine whether it was the feed or other. I moved the antenna and it cleaned it up. Also connections needed to be cleaned a bit. I may put a dab of RTV sealant on the connections as they are out in the weather and can become corroded. That includes the connector to the rabbit ears antenna and the Coaxial cable RG-6 going to my receivers. Receivers are a magnavox DVD Recordable, Homeworx DVR/Receiver, and a TV with the digital receiver built in. Sometimes the splitter inside the house just needs a little reattachment of the cabling.
Sometimes I have seen where the center core of Coaxial cable has shortened itself and now has an emotional attachment over a physical attachment to the connector. In this case, emotions are bad...physical is good.
Heck, check it with a tv in a different room with a different cable. Troubleshooting 101....check all switches, dials, and connectors. Dont forget fuses if there are any. Did time for not looking for a burned fuse one year. It was ugly. But that is a story for a different time.
Just some ideas....good luck and enjoy the offseason.
