Howard,

There is a typo in the last line:

LSB.REV >> LSB,REV

I don't know in detail how SATPC32 parses the Doppler file. This probably isn't the source of your problem, but it needs fixing. Then restart SATPC32 with your fingers crossed. ;)

Does it matter if you rearrange the 3 lines so the default mode changes?

Howard, I tested that with the FT-817 as "Radio 1" and the FT-847 as "Radio 2" (I don't have an FT-897). My settings in menu "Radio Setup": Radio 1: FT-817 Cat baud rate: 38400 COM port x CAT delay: 20 Radio 2: FT-847 CAT baud rate 57400 COM port y

Option "Autom. Rx/Tx change" checked, all other options in the menu unchecked. That worked flawlessly, also with HO-68.

The same test with the FT-847 as "Radio 1" and the FT-817 as "Radio 2" worked also flawlessly.

In menu "Options" I have set the SGP4SDP4 model. The SGP8SDP8 model causes a math error with HO-68 ("Ungultige Gleitkommaoperation" = "Invalid Floating Point Error"). The reason: In the Keplerian data sets for HO-68 the value of the element "bstar drag term" (line #1, col. 54 - 60) is 0. I have fixed that and there is a patch file on my website, Engl. page "Downloads" , "Patches".
