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.

There is a slight outcropping between the start and finish which is probably
enough to rule out the FRS radios.

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

I have contacted them and will see what they say.

If they have questions, I could get them in touch with the hams who
set up the Head of the Charles.

I'd like to use GMRS radios to run a rowing regatta (in the U.S.).
These require an FCC license but the GMRS license
(http://wireless.fcc.gov/services/per...generalmobile/) is limited
to an individual and members of his household and relatives.

While I agree with others that it would be an excellent idea to get the
local amateur radio organization to provide (free) communications for your
regatta, I wonder why you hadn't also considered the FRS radio system?
No license, cheap equipment, and should be able to provide your
communications requirements for a regatta, assuming you don't have hills or
other obstructions to talk past.

The range of 1/2 watt FRS radios, advertised as "up to 2 miles", is
more like 1/2 to 1 mile in real world conditions, and terrain and
architecture can reduce that further.

A typical 2 meter ham HT puts out 5 watts, has a better antenna, and
has access to repeaters. Much greater range.

There are only 14 FRS channels, and anyone can jump in with their own.
The PL tones do not help that much if there are other users on the
same channel.

If your event ends up buying radios, it can add up rather quickly.

We see many events try other means of communications, and they end up
coming back to asking hams to help out.
