I'm in the Chicagoland area and use the EA. We've had snow most of the day on Tues but none in the evening. I get the local HD channels but not the higher ones such as FX or History. When I tuned in History HD there was message saying I was being changed to the SD channel & this did come in OK. Even if the storm has moved eastward & blocks the signal, or blocks the uplink, why would local HD channels or History SD make it through? Is this more likely an issue of signal transmission to or from the satellites? Or would it be a problem with snow buildup on my dish or ice on an LNB? If it's my Dish I have no idea how to clean it off. It's on the roof near the edge but it is 2 stories straight up.
