Ok here is my setup. I have a dish for 61.5 and a separate dish for 110+119. 2 lines from 110+119 dish and 1 line from 61.5 go to a DP34. 4 Outputs of DP34 go to 2 dual tuner receivers that all work fine. Added an additional DP34 switch off the 1st DP34. have 3 wires going from 1st one to the second. Here is where the problem begins. I ran 4 wires out of the new DP34, 2 to one room and 2 to a bedroom. I have tried 2 different receivers and both have same problem at either location. It is a dual tuner 522, Tuner 1 sees all 3 orbital locations however tuner 2 does not see 110. I have tried replacing the second DP34 with another but that did not fix. I have tried 2 different 522s and that did not fix it. The wiring is brand new. Could the outputs of the first switch to the second switch be bad? If so why would tuner 1 work for all 3 but not tuner 2? Any thoughts or suggestions I would greatly appreciate. If you need more info please let me know. Thanks!!
