Andy,

All good ideas. The beacon transmit sequence could 
start at the top of the hour and every 15 minutes 
after that. The 5mhz U.K. beacons (GB3RAL) use 
this timing.

Keeping the beacons synchronized without an 
internet connection would be a problem, but I 
guess there are ways around that.

Some of the NCDXF beacons are in remote locations 
and they solve their timing issues with GPS. It's 
amazing how well the system works keeping all 18 
beacons in sync.
