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:
CAT baud rate 57400
COM port y

Option "Autom. Rx/Tx change" checked, all other options in the menu
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" ,
