[amsat-bb] FW: Doppler file

Thu Dec 20 12:32:33 UTC 2018

Ted,

Have the above answered your questions?  Seems to me two different issues
have been mixed here as the Keps and Doppler.sqf are two different items
and updating one does not up date the other

   1. The Keps can be updated from a number of sources to be found on the
   drop down under the <Satellites> tab
   2. Doppler.SQF is manually updated by you when a new satellite is added
   to the family using Notepad or some kind of text editor.  Be sure to follow
   the rules embedded in Doppler.SQF when messing with the file.  You can save
   a copy that has not been modified the the Uplink calibration process as
   Doppler.REF or some such thing.  And, yes, each radio has slightly
   different calibration offsets in Doppler.SQF.  That is what I use the 4
   different configuration options for <Setup><Configurations>.  I use one
   config for a pair of FT-817's another for an IC-910H and a third for Flex
   6600.
   3. Don't forget if you are adding a new FM satellite to Doppler.SQF you
   also need to go into Subtones.SQF and add the new satellite to that list as
   well so the T0 > T1 >T2 toggle works correctly.  Again follow the embedded
   instructions carefully.  This is another file that can be manipulated with
   a text editor like Notepad.

Hope this helps,

John
