Hello Thomas, 1/ The fdmdv modem can sync up with +/- 200 Hz frequency offsets. Once it's synced it will track changes in frequency offset of several Hz per second. So tuning and drift are less of a problem than for regular SSB.
2/ I am running the prototype fdmdv2 GUI program on a 4 year old laptop (dual core 2.4MHz) at about 30% CPU load.
