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.

The Private Land Mobile Radio Service license
(http://wireless.fcc.gov/services/plmrs/) looks like it might be what I
need, but I'm not sure about that. Also the fee for a PLMRS license for a
non-profit is $55 per call sign. Can I use GMRS radios with a PLMRS
license? Does each GMRS radio count as a separate call sign? Maybe this
suggests that PLMRS is not the appropriate license?

Thanks for any help.
