I am having trouble receiving signals on a Dish 1000 and am wondering if anyone can help. The system has two receivers, a 622 and a 625. I am using a DPP Twin LNB with seperators on each reciever. When I run the switch test it says I am receiving sat 110 on input 1, nothing on input 2 and sat 119 on input 3. This does not seem right and obviously missing sat 129 is not normal. Any help will be greatly appreciated.
