Hmmm... I have the same firmware version in one of my
Birdogs and I get T5 just fine. When your meter beeps and says "Found" are you immediately pressing the "down arrow" button? That will indicate your signal quality.
If you still can't get it I would suggest reconfiguring the download file and reprogramming it into your Birdog. Make sure you download the correct version -- ie: there is a file for "standard" LNBs and another for "universal" LNBs; the "universal" files start with "U" and they are at the bottom of the pick list. I never use universal LNBs so I can't attest to whether or not the "universal" files even work.
