Hi folks, newbie here. I'm in an RV, using a Kingdome 9702. Dish says I need to be on sat. 129 to get locals in HD. I have a good signal strength, did a check switch and a reboot, but the check switch says input #1 OK on sat. 129, but just XX on input #2 and Switch SWAJ. I can't record one program and watch another and some channels won't record at all. Like I said, newbie here. Oh and the receiver is the Vip722k. Thanks in advance for any help!

welcome :wave

You need two cables from the dish to the receiver. The kingdome units are what they call Legacy so you need two lines to the receiver.
You already did a check switch but I had this same issue before too. Select "Alternate" in the check switch screen and see if that fixes it. It shouldn't say any switch if you're aimed at just 129
