I have a 20 inch dish with 2 dual lnbs, 2 sw-21 switches and 2 recievers. My problem is i can find the 110 and 119 signals individualy with a strenght of about 90 but when i lock on 119 i can't find 110? When i run a switch test i get 119 odd 119 even and then the rest r all X's, with a "only one satellite is connected warning"! The other thing is when i switch from 119 to 110 in the singal meter screen the bar goes red and i get a wrong sattelite 119 message on all transponders but a 90 signal? Any help would be greatly appreciated!
