SatPC32 sets the FT-847 sub tone frequency for SO-67 (233.6 Hz) correctly.
I suppose you have the following data line added to SubTone.SQF:
The Parameter $01 is the code of the FT-847 for a 233.6 tone. .
To check the tone frequency do the following:
Select SO-67. CAT steering must be on (C+)
Click the control T0 to T1. Above the VHF uplink freqence an "ENC" appears.
Disable CAT (C-).
At the radio switch the bands. The VHF frequency must be on the left side.
Now press the "Menu" button at the FT-847 and select menu #12.
In the display you will see the tone frequency 233.6.
