Does it actually make sense to change=20 the phase reversal time? Since the samplerate is drifting anyway, there=20 will be a small time difference between a phase shift and there=20 zero-crossing. Also -if the samplerate would be exactly 24 kS/s-, the=20 time when the phase shift occurrs can be somewhere, i.e. wouldn't be=20 sync'ed to the zero-crossing. Right? So it may be easier (also for the receiving side) to let it remain at=20 0.1 seconds. Comments welcome. 73, Stefan/DK7FC Am 30.01.2012 19:24, schrieb Stefan Sch=E4fer: > Changed the phase reversal time from 0.1 s to 0.111482720178372 s=20 > (=3D1000/8970Hz) Seems to work.
