Hi Graham, LF,

What about asking for a mod allowing support of a DDS ?

MSK/CMSK has only two tones, whose frequencies are known. Therefore only one
bit of information is required for one symbol.
The big question is how much accurate the deltaF has to be ...

Graham, since I swapped the link between the PC and the LF/MF transmitter
from USB to BlueTooth, the timing has slightly degraded, and as a result
ROSmodem is not working anymore. I have to resync the timing at the PIC
level, definitely the correct way ...

73,
