You're very welcome.
What they require back is three things. The modem, the power pack for the modem, and the radio from the dish. The radio is the boxy thing with the "eye" attached to the end of the arm on the dish.
I'm pretty sure this PDF is current, which shows what needs to be returned. I believe the return kit also includes a sheet that shows what is needed and how it should be packed in the box (they send you the box).
