So I have the answer. Spoke to a tech at commercial communications equip. shop who knows all about the Birdog meters and has done programming of them.
The Birdog USB Plus meter cannot distinguish the difference in data streams between the Bell 82 & 91 sats and identifies them as both being locked onto at the same time. He says to peak the signal on one of them and see what sat you've got showing on your TV and if that's not the sat you want, re-adjust the dish the appropriate no. of degrees and peak the signal for the other one (if using one LNB).
Not quite how I expected these meters to work.
