I am trying to set up 3 receivers to a 2 dish system one dish with a single lnb gets 61.5 the other sat is a DPP twin lnb with 3 connections called 1.2.lnb ive verified that 1,2 go to the receivers and the one marked lnb is connected to the 61.5 sat lnb. can i use this setup for 3 receivers or do i have to replace the dpp twin I also have a dpsw34 switch to use? thanks in advance for any help!
