[amsat-bb] Setting Doppler for SSB Satellites in Doppler.sqf

[Burns Fisher]

Just to clarify a bit more, the value in the doppler.sqf file is the
frequency that the satellite will be receiving or sending.  So when you
look up the satellite and it says the passband is from x to y, then you put
it in the middle of this range.  Ignore doppler and let the software do it
for you, at least on the radio that you can do CAT with.
