Introduction

TALKGROUP SELECTION

A trunked system can be divided into different talkgroups. This

enables the system owner to organize the talkgroups into commu-

nication groups according to function. Members of a specific talk-

group hear only messages intended for their talkgroup. For

example, if talkgroup B is selected, you will not receive messages

for talkgroup E.

The GTX mobile radio can operate on both trunked and conven-

tional radio systems. Conventional typically refers to radio-to-radio

communication, sometimes through a repeater.

A trunked radio system allows a large number of users to share a

relatively small number of frequencies without interfering with each

other.

The air time of all the repeaters in the trunked system is pooled,

which maximizes the amount of air time available to any one radio,

and minimizes channel congestion.

Some of the overall key beneﬁts of a Motorola Trunked Radio Sys-

tem are:

•

No channel monitoring required prior to transmission.

•

Improved system access.

•

Automatic channel selection.

•

Increased privacy among members of the same group.

•

Only one attempt is required to access the system. If all chan-

nels are busy, the call request enters a queue and the central

controller automatically assigns the next available channel. Two

(2) medium-pitched tones followed by one (1) high-pitched tone

sounds when the call can be made.
