I have considered FRS, but testing suggests that its range is
insufficient. We will need to communicate over a range of up to 2-3
miles. Even though the conditions are very good, I don't think FRS
can do it, but I would be delighted to be wrong.



Is this event held over line-of-sight water? If so, the FRS radios
should work, though close to maximum range there. If there is terrain or
just trees in the way, then 2 - 3 miles won't work. Be easy enough to
probably get a pair to check the path over your maximum range, though.

As others have said, you'll get a much higher quality communications
system if the local hams do it.
