Searching for a Narrow Keyboard QSO mode suitable for QRP on 630m.
I went back to a program I used several years ago.
Currently Testing GMFSK not to be confused with gMFSK which is a
Linux program.
GMFSK is an FSK Mode using Varicode by JE3HHT Makoto Mori included
in MMVari.not new program it is of the usual high standard found
in his software.
GMFSK has variable width, currently I am running at 15.625Hz wide.
474.200 Dial 1900 tone frequency.
JE3HHT provides fine documentation with his software, for some
reason all the other modes covered by MMVari are well covered but
when he gets to GMFSK he says that it is beyond the scope of the
instructions. I have yet to find more details about the mode.
This Mode should be
better than RTTY and faster MFSK for higher power stations too.
