This may be a weird question but are you able to ship me a switch?I think I have a 510 . I do have a 622 922 and a hopper sitting in my basement. Several switches . I remember the days of buying all of the newest satellite equipment as soon as it came out. I still have my original dish 500 self install kit with the plastic compass. I hooked up the dish so many times I can walk out and point it blindfolded. I think I have a built in compass. If they switch back to 110 and 119 it will be time to break out the old compass and look for signals between the trees .
