Do you have a BUD install Kit (2 way
diseqc switch, 2 x hi freq splitters, rg6 cables)?
Try connecting the KU cable directly to your 301IR receiver. Use your analog receiver to move the dish (let's say to
Telstar 5). Your 301IR should be configured to the right KU LNB type.
Select Telstar 5 on your 301IR, check to see if you are getting signal and quality. If yes, do a channel search.
