[amsat-bb] FW: Doppler file

[Bob]

Hi Ted,

As nice as it would seem, it really isn't possible to automatically update
the DOPPLER.SQF file.  The most important reason is that each station has a
different transmit and receive offset due to different RX and TX chain
frequency calibration, drift, etc.  It would be possible to have a baseline
SQF file (without compensation) and a few hams do publish that.

You can manually update the Kep files yourself.

73, Bob, WB4SON
