Hi Hans,
Just wondering if you could clear something up for me please.
I thought timing sync came from the nmea data from the gps. It looks to me that once a pps signal is received, the U2 takes its timing from that rather than the nmea data flow. I've noticed this because my U2 kit is located in a marginal gps signal location. On occasions the heart beat on the lcd will stop every now and again and as a consequence the time will be wrong after the tx period.
If this is the case, it may make more sense to have a time resync straight after a transmission period as any time discrepancy over 12 seconds may mean the kit misses the next tx frame.
I am wondering if anyone else has noticed this phenomenon?
