Welcome to SatelliteGuys Gary.
Well someone has set that receiver up to hack DISH Network. Which of course is stealing and is not condoned here. If you want to use it for true FTA you will need to see if you can find firmware to restore it back to a proper FTA receiver.
Then it being an older model may not decode most of what is up there, as most stuff has went to DVB-S2. Might be better to get a newer receiver. That is if you want to pursue true FTA.
What kind of dish is it? If it is a DISH or DirecTV dish, it will be too small for FTA work, so you would also have to get a new larger dish.
It should be also noted that with true FTA you may get some of the main stream channels and you may not. Things come and go, and that is the part of this hobby. The fun is to see what you can get and find that is IN THE CLEAR and not scrambled.
We will be more than happy to point you in the right direction!
