Coverage/range
The maximum range depends on terrain condition and is obtained du-
ring use in an open space.
The only limitation to maximum possible range are environmental fac-
tors such as blockage caused by trees, buildings, or other obstructions.
Inside a car or a metallic constructions, the range can be reduced. Nor-
mally the coverage in the city, with buildings or other obstructions is
about 1 or 2 Km. In open space but with obstructions like trees, leaves
or houses the maximum possible range is about 4-6 Km. In open space,
without obstructions and in sight, like for example in mountain, the co-
verage can be more than 12 Km.
Warnings
Do not open the radio for any reason! The radio’s precision mechanics
and electronics require experience and specialized equipment; for the
same reason, the radio should under no circumstances be realigned as
it has already been calibrated for maximum performance. Unauthorized
opening of the transceiver will void the warranty.
