I recently had 2 HDDVR's (HR24) installed at my house at zip code 41102. They worked fine. I bought an additional slimline dish from the installer for my camper. I am now in PA zip code 15672 and have been trying for 2 days to get the dish tuned in. Yesterday I bought new RG6 cable and have tried it today. On my dish setup I have Dish type=03 Slimline3 switch type =01 SWM and tuners=single. The coax is plugged into #1. I am getting a cannot detect SWM. The cable goes directly from the dish LNB to the HR24 #1. Do I need a power source?? What is the problem somebody please help. I am pointing at AZ 221 Elev 38 and tilt 68.
