Installers don't always have the exact model available to them. Any receiver in the 722 family (622/722/722k) can be replaced with any other. When Dish ships you a replacement, it will be identical. When an installer comes out he can only use what he has on his truck, which could be any one of the three.Jhon69 said:John:
When a installer replaces a receiver their supposed to replace it with one that works like the other one you need to contact that installer(or DISH) and have him come out and fix your problem.Good Luck!
If you complain to Dish enough you might be able to get them to give you an MT2 OTA module to install in the 722k though - which would give you 2 OTA tuners instead of the one built in the 722.
