Does anyone know if the ICOM 9700 is capable of 9600 baud in it's current form or will it have to be modified?

"Hi Tony,
Quite a few of us have tried. Briefly, NO. We can receive at 9600 baud sort of (quick explanation follows), but cannot get the radio to transmit at 9600.
I don't think I was ever able to use the audio out of the radio (FM-D, etc) into a real TNC and decode it. Not sure anyone has...
To receive--use the IF via USB audio; use a program like SDR# with FM (all filters off, 10-12kHz wide), feed that audio into hs_soundmodem that then connects to PacSat Ground Station software.
Sadly, the fplks at iCOM are not responding to the request several of us have made to figure out a way to get to work at 9600. Surely it's doable---but iCOM doesn't seem to think it's worth the time/investment...

John:
I'm aware of the thread but the follow-up question is can it be done? We assume that 9600 baud TX can be done with firmware, but is there a possibility that the rigs architecture and code are more complex than we thought?
That might explain why Icom hasn't responded. Just a thought.

That is possible, I was just going with everyone else's assumption that it shouldn't be impossible and might not be that hard.

What about a software based TNC or a Mobilinkd?
Experiment with something like this?

Or is the TNC not the problem ?
