I have new 722 and 211k receivers and get good OTA signals from the locals with them. Will I be able to see these channels in the event of total satellite signal loss due to heavy rain? Any magic button pushes to get past the usual signal loss message displays? I was offered a few threads on this topic before posting, but the newest is 4 years old so I don't know if the comments there are still valid. The weather forecasts suggest I'll be able to find out for myself later this evening, but I'd rather be prepared, especially the part about getting around the signal loss displays.
