Hi!

I looked at the documentation, and under GPS time stamping there is a note that says GPS sync is not needed for RDS AF.

This still does not specify this: are MicroMPX decoders running somewhat in sync between multiple transmitter sites? (eg. so that the audio received by the listener at least appears to be in sync with each other when bouncing back and forth between frequencies because of AF)

So some kind of crude timestamping at least? Using NTP?

There's no crude time stamping but all the clocks are synchronized to each other, which typically keeps it within a few milliseconds, which is good enough for AF switching.

Yes, that's very good!

Thanks for your response!
