It was the Brighton half Marathon today.
The hytera dmr trunking system they put in (massive antenna on a wind up stand on hove lawns) failed during the race, for at least an hour loss of comms.
Only back to back users were working, such as the finish line zones.
Anyone have any insider knowledge as to why the comms failed - sounds like a power or repeater controller issue.
There were lots and lots of very angry people at the marathon ........
