GMRS Interstitial Simplex
& FRS Frequencies
Interstitial frequencies are available
for simplex use by all GMRS licensees. Operation on these channels is restricted
to GMRS Small Base Stations and GMRS mobile units operating with 5 watts or less
of effective radiated power. GMRS shares these channels with the hand-held
radios of the Family Radio Service. FRS radios are limited to 0.5 watts.
Operation on these frequencies is license-free with an FRS radio, but requires a
license with a GMRS radio.
