Bill,Thought about the zero-crosings. Does it actually make sense to change the phase reversal time? Since the samplerate is drifting anyway, there will be a small time difference between a phase shift and there zero-crossing. Also -if the samplerate would be exactly 24 kS/s-, the time when the phase shift occurrs can be somewhere, i.e. wouldn't be sync'ed to the zero-crossing. Right? So it may be easier (also for the receiving side) to let it remain at 0.1 seconds. Comments welcome. 73, Stefan/DK7FC Am 30.01.2012 19:24, schrieb Stefan Schäfer: Changed the phase reversal time from 0.1 s to 0.111482720178372 s (=1000/8970Hz) Seems to work.
