FRS?
Channel scan allows your FRS radio to scan all FRS
frequencies for signals. After scanning briefly to see what
channels other users are on, simply set your FRS radios to
an unused channel and enjoy less interference.
FRS Limitations
If you are operating in an urban environment or in
varying terrain such as canyons or mountains, some
features act as obstructions limiting the maximum
reception range of your FRS radio. The UHF FRS
frequencies are “line of sight,” meaning that the signals
do not follow the surface of the earth, but instead radiate
in a straight line from the transmitting antenna. If there
is an obstruction between the transmitting FRS radio and
the receiving FRS radio, the signal will not be received.
Smaller obstructions, such as trees, cars, and even crowds
of people cause some loss of signal, resulting in reduced
maximum range.
GMRS
The use of a GMRS (General Mobile Radio Service)
radio requires an FCC license in the U.S. No license is
required in Canada to operate on GMRS channels. The
operating frequency of GMRS ranges from 462.550 to
462.725 MHz. Refer to the “Frequency Charts” for a
complete list of each channel’s frequency.
