This question has been posted in the past and never answered fully. How to read the DPP Twin with a Birdog? I know the DPP does not switch until it connected to a receiver, there are some rumors that one can not use terminal one to connect to the meter. I am not having any luck seeing 119 on my meter. This comes about because we are a bit South and can not see the 110 Sat but still want to use the Twin to marry to a Dish Pro dual and get both 119 and 129 with a DPP signal so as to use only one line to the dual receiver. We hang the DPP twin onto a larger dish and its very hard to just swap LNBs so as to use a single or normal twin to check signal. Has anyone found a way to read the 119 signal with the Birdog from the DPP Twin?
