[amsat-bb] Fw: Fwd: LVB tracker

It isn't shown on the schematic, but elsewhere in the rotator docs (page 5, External Control) it 
specifies 0-4.5V DC for the position sensing outputs.  Depending on the existing interface, a simple 
voltage divider would probably do.  I don't have an LVB tracker, so I can't comment on that end.
