In the interest of being a bit more complete, there is a file needed that
has the radio tuning details for the satellites.

Erich covers the details here if you need to add satellites to your
doppler.sqf file which contains the tuning information for each satellite,
and in some cases, you'll have multiple lines for different scenarios on a
given satellite:

The information on what the doppler.sqf file is, where it is located, and
how to update:


If the data needed for the satellite(s) you're interested in working is not
in your copy of SatPC32, the data is probably here:


To edit the file, select the ? pulldown, then click auxiliary files and
you'll see the doppler.sqf - click that in the menu to review the guidance
and add your satellite of interest.

If you're setting up for an FM Satellite...the exercise for the student is
to look at the subtones.sqf under the ? --> Auxiliary Files menu and review
the PL Tones in the file if you like working the FM Sats...thats where you
configure the tones.

Hopefully this points to more answers than questions.
