My parents on my second DISH account have a 722k and western arc dish 1000.2 + a side sat for 61.5 ,that we installed when you could only get hd on that sat. Now they have Houston,Tx locals and they are on both 110 sat western arc and 61.5 on eastern arc. They were watching delayed , a recording of ABC show Good morning America and it was stopping, speeding up and was acting very jittery. I looked and the recording was being made off of the 61.5 sat. I checked the dish point screen and the signal strength was very low at only 27 on the spotbeam. So I went on the roof and removed the 61.5 side sat coax into the 1000.2 western arc dish and re-ran a check switch. So now the locals only come off of 110 sat. No more jittery ,skipping, picture. My parents said that the picture had been doing that for a while now. But then again my dad always makes every problem seem like it has been that way for ever. So for some reason the locals kept defaulting to the lower signal on the 61.5 sat.
Now on my account I have Beaumont, Tx locals that come off of 61.5 as well and I have seen no problems with my picture using my hopper and eastern arc 1000.4 dish + a side sat for 119 sat. So I know that the only connection is that they both come off of 61.5 sat ,but I have seen no difference in my recordings or live tv off of my locals.
