All,
A little help with SAT pc 32. I just started to play around with decode the NOAA weather sats. I want to get the frequencies into the dopper.sqf file so I can see the Doppler correction. I've edited the file and only two of the three sats show the frequency. The format is the same for all three:
NOAA 15,137620.0,,FM,,,,
NOAA 18,137910.0,,FM,,,,
NOAA 19,137100.0,,FM,,,,
NOAA 15 is the culprit that won't show.
I've looked with a fine tooth comb for any differences and don't see any. I also looked in the KEp file for the Weather & NOAA sats and the sat name is correct. Anyone see what I'm missing.

Do a hex dump of the file so you can see what's invisible (like control characters, etc).

Use this

to do the hex dump, if you don't have anything better...
Rick, There is something very unusual going on here. Satpc32 does not like certain letter formats. Not sure just what's going on. Humor me. Open whichever TLE file you're referencing. (Those satellites are listed MORE than one TLE. Ask me how I know.) Copy and paste the satellite name from the TLE to DOPPLER.SQF. I have the WX sats in their own "group" referenced to the "NOAA" TLE. BTW: the last character (unprintable) in each line is a carriage return/ line feed (0d0ah), supplied by hitting "enter" on your keyboard. That is the "end of string" character that the parsing routine loading DOPPLER.SQF is looking for. No end of line character, it throws away the data. (I think..) Norm n3ykf

Hi Rick, in the file Doppler.SQF change the name of NOAA 15 to NOAA-15 (insert a minus char instead of the space in the satellite name). The program then should display the frequency for that satellite.
The reason that SatPC32 doesn't show the frequency if you use "NOAA 15" but shows the frequencies of "NOAA 18" and "NOAA 19" in Doppler.SQF is a bit complicated: Handling of the satellite names is difficult because the source files for Keplerian data (SpaceTrack files, Celestrak files, nasa.all) often use different spellings of the satellite names. Usually the Amsat names (used in nasa.all) are much more handy than - for example - the Celestrak names.
Therefore SatPC32 can optionally convert the satellite names of the source file to their AMSAT name, provided an AMSAT name is available. In menu "Satellites" > "Sat Names" you can choose the option "Use AMSAT Names if Available". I suppose you are using this option since it is the default setting.
With this option the program identifies a satellite by its catalogue number or international designator and then checks, whether the aux. file "AmsatNames.SQF" (that can be opened from menu "?" > "Auxiliary Files") contains an entry for that satellite. If so, the program uses that name in menu "Satellites" and expects that spelling in the other aux. files - for example in "Doppler.SQF", "Prior.SQF" etc.
The aux. file "AmsatNames.SQF" currently contains an entry for NOAA 15 with the spelling "NOAA-15", it doesn't contain entries for NOAA 18 and NOAA 19. Therefore it expects "NOAA-15" in Doppler.SQF but accepts the original spellings NOAA 18 and NOAA 19.
So, if you want to add new satellites to the program have also a look to file "AmsatNames.SQF".

Rick,
You might take a look at this. It works for me and might help you.
