Is there a way to synchronise the 2 radios without an external PPS? Is
there an internal PPS available to the daughter-boards when the clock is
set to "internal" on the mother-board? Or can we simulate something like
We do have the Board Mounted GPSDO installed if that might help at all.
We have solved the problem before as mentioned with the OctoClock, but the
OctoClock is not available any more, and using the OctoClock to sync 2
radios on the same device is overkill.
