What You Hear On A Channel - Tait TM8100 Guide De L'utilisateur

What you hear on a channel

Your radio may be programmed so that you hear all
conversations on a channel, or your user group may be
segregated from other user groups by using special signalling.
The special signalling is used to control the muting and
unmuting of your radio, so that your radio is muted when other
user groups are talking and unmuted for members of your
user group.
There are two muting controls that operate in your radio:
signalling mute, and
■
squelch.
■
Signalling mute
The radio's signalling mute only allows the radio to unmute if
the incoming call carries the tones specific to your user group.
Your user group may use tones that are either audible,
subaudible or both.
Squelch
The radio's squelch allows the radio to unmute only when the
strength of the incoming signal is above a predetermined
threshold. This means that only signals of reasonable
intelligibility are made audible.
