CONVENTIONAL RADIO SYSTEMS
Conventional radio systems typically refers to
unit-to-unit communications through a single
channel. Conventional systems also allow
radio users to extend communication coverage
by relaying their messages through a repeater.
To ensure coordinated use by multiple
talkgroups, each radio user must monitor the
channel or repeater before transmitting to
verify that the system is not currently busy.
