Hi Graham, LF, > As far as I know , only wspr and ros-mf have the ability to drive a > pic/dds vfo , with only mf-1/7 giving a tailored mf qso mode ? 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, Michel - F5WK |
