No - FRS and GMRS are same tech, but GMRS may be newer rules, and is
permitted higher power. FRS and GMRS share some channels, so FRS and
GMRS radios can communicate with each other on those channels (but
GMRS is limited to FRS power levels)
Well actually not quite right, but very close for a Canadian, Peter.
GMRS has been around for ages, like 40 years or so, and was the first
US based UHF Radio Service for General Public. It originally was called
Class A Citzens Band Radio Service. The Frequency List was expanded
when it was reruled to GMRS, and has been fairly standard since.
FRS was designed, for low power, simplex, short range, family
communications, and the Limited Frequency List came from a subset of the
GMRS Frequency List. Where GMRS allows Repeaters and duplex systems,
FRS does not. Where GMRS is a Licensed System, FRS is done via National
Blanket License. GMRS and FRS Stations MAY communicate with each other
on dual use frequencies, FRS is limited to their Subset Frequency List,
only, and have no Interference Protection from other Radio Services, like
GMRS Licensees may be able to command. Power for FRS is limited to what
is specified in the National Blanket License, where GMRS is limited by
the Station License issued for each System.
