NO. I was simply saying that the open source is there for the 4800 bps GMSK sound card modem. NOT using D-STAR Digital Voice. That has already been done via satellite.
NO, I was just saying ignore the high speed mode.

Ah, thanks for clarifying. Unfortunately, if I understand you correctly, we would have to talk to our satellite via digital voice, or at 128kbps, which would be great if we could!

Well, make that the digital voice part of the protocol. The high speed digital data part is up to 128kbps which was not what I was thinking of.

Hi Nate,
the D-STAR protocol is only GMSK at 4800 bps and they selected a time-bandwidth product of 0.5. 4,800 bps or 4k8 is perhaps not talked about as that IS the standard for D-STAR. So the software there might be adaptable. that is the reason I thought to suggest it.
Good luck and 73, Tom n4zpt

Hi Tom,
My mind had indeed played a trick on me, and I remembered MFSK as MSK.
As far as the DStar group goes, I don't see any mention of 4800 bps or 4k8 kbps on the public page, so if it's not the group's focus, I don't want to have to rely on that solution.
Thanks, -Nate KC2SVI
