Can anyone tell me how to hook up the switch on a dish 500 leagacy feed horn to the 1000 dish network reciever? Do I need something for the features jack out the back of the unit to turn on the switch in the feedhorn. I have 97% signal level on 119. The switch test fails on the check and the dish 500 box has been checked. The skew has been set and the azimuth is right ( I think) heh. Its an old unit and I dont think the newer ones work the same lol! thanks ya all
