Hey Sooner, I also lost my OTA as well as my sister when we both got the L612 upgrade for the 622. I finnaly got the L613 but that didn't do anything. I tried everything from a hard reset to deleting the channels and rescan. No luck. I know it's the receiver because I also have a 722 and put that one where the 622 was and I scan and get 43 digital channels. I put the 622 back and rescan and get 1 digital channel. This is not the first time this has happened. DishNetwork screwed up the codes in the software once again.
