I know on Delphi XM radios you can do a "2-0-7-xm" to bring up a diagnostic screen that shows the strenghth of the two birds and terr repeater. You can then adjust your home antenna for minimum BER. Is there a similar technique in the old Sirius Orbiter where you can 'run the numbers' to help set-up your home antenna, especially now that they've finally got a geostationary sat?
