talkgroups you wish to monitor.
Traditional conventional radio
systems operate using a single
radio frequency for each group of
radio users, and in some cases,
multiple groups sharing the same
radio channel in the same
geographical area. This frequently
results in heavy traffic and often
requires that radio users wait long
periods for the frequency to clear
before they can place their calls.
Trunked systems allow large
groups of radio users to use radio
frequencies more...

85 The control channels for some
Motorola trunked radio systems
may change on a day-to-day
basis. To ensure that you will not
miss traffic when the control
channel changes, enter all the
known control channel
frequencies into the channel
storage bank. If the control
channel changes, your scanner
will automatically lock on to the
new control channel. If you do not
know which system channels are
used for the control channel
operation, we recommend that you

You may find it necessary to set
the control a bit further in the
clockwise direction to prevent very
weak signals or interference from
stopping the scan operation.
