Licensing Requirements
This radio device requires an FCC license prior to
operation in the United States. Other countries may
have similar requirements. It is the purchaser’s
responsibility to acquire all applicable operator
licenses.
Radio Overview
The operational range of the 1W radio varies with the
undulation of the topography, the density of foliage
and man-made materials (i.e. buildings), the type of
antenna employed (NavCom offers a half-wave
antenna), and the height of the base antenna. A
broadcast range of 2km is not uncommon, but will
vary greatly based on the operating environment. If a
longer range is desired, NavCom offers a 35W radio
option.
The user configures the radio via software running on
a hand-held controller or a PC. Specifically, this radio
is controlled via the [RADIO] command on the Input
Terminal. This command controls turning power on
and off to the radio as well as setting the carrier
frequency, the transmit power, the signal threshold,
and the network ID. A user can also schedule
[RADIOSTAT] messages to report the current status
of the radio. Refer to the Sapphire Technical
