you.
In a trunking system, one of the channels that
is used to provide a continuous, two-way/data
communications path between the central
controller and all radios on the system.
Typically refers to radio-to-radio
communications, sometimes through a
repeater. You share a frequency, or
frequencies, with other users without the aid of
a central controller to assign communication
channels. Therefore, you should monitor each
channel before transmitting to avoid interfering
with another user who may be transmitting.
A visual tracking marker (a blinking line) that
indicates a location on the display.
A continuous, sub-audible data signal,
transmitted with the carrier.
An individual who has radio system
management duties.
