Not sure about the controller, contact
RF Mogul and see about the programming as MotoSat is out of business and RF Mogul was started by some former employees. Yes the LNB's will need changing, maybe even the dish itself. Not sure if parts are even available to do it. I know of one place in Junction City OR that has a lot of the old MotoSat units laying around that might have the parts.
We have the MotoSat HD Direct dish on our unit, the Nomad controller burned out so I replaced it with the RF Mogul Eagle RF-1 controller and it works perfectly. Very fast lock on too.
