What you hear on an analog channel
On analog channels, 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 signaling. The special
signaling 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:
■
signaling mute
■
squelch
Signaling mute
The radio’s signaling 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.
