Glossary

Squelch The muting of audio circuits when received

signal levels fall below a pre-determined

threshold. With carrier squelch, you hear all

channel activity which exceeds the radio’s

preset squelch level.

Standby An operating condition whereby the radio’s

speaker is muted but still continues to receive

data.

Talkgroup An organization (or group) of radio users who

communicate with each other, using the same

communication path.

Tone Private-Line

(PL) Coded

Squelch

A continuous sub-audible tone transmitted with

the carrier.

Trunking The automatic sharing of communications

paths between a large number of users. Allows

radio users to share a smaller number of

frequencies because a repeater, or

communications path, is assigned to a

talkgroup for the length of a conversation.

Zone A grouping of channels or talkgroups.
