I have a VIP222 receiver that I'm wanting to take on a camping trip over Labor Day. I found a Dish 500 and 300 to use, but the 500 has DPP LNBs on it which I'm finding out won't work with the receiver. If I unhook any of the 3 (110,119,61.5) satellites from the switch it gives me a "complete signal loss" error (when attached to the current switch for the house). If I do a switch check it tells me that it can't find as many satellites as it previously did, and that I'll experience channel loss which I can deal with. But then it just craps out telling me I have "complete signal loss" again. Is there any way possible for me to use the Dish 300 and only feed the receiver 110 or 119?
