I was not aware MixW had MSK in it but still identical to GMSK. Perhaps
you are thinking of MFSK? In the MixW program there is MSFK16, a
multitone frequency shift signal, is supported, but not Minimum Shift
Keying or Gaussian Minimum Shift Keying signals. And also FSK, aka RTTY.
There is work going on to make a sound card 4800 bps 0.5 time-bandwidth
product GMSK soundcard modems for use in GMSK DV adapters to use with
D-STAR radios. Perhaps that could be adapted for your purpose?
http://www.qsl.net/kb9mwr/projects/voip/dstar/G4KLX.html seems to
describe some of the work.
ttp://groups.yahoo.com/group/pcrepeatercontroller/ are where I see the
Separate discussion is using an external sound card interface like the
Rigblaster, to connect a computer and radio.
