Monitoring Talk Group IDs

You can use your scanner’s display to monitor the fre- quencies/talk group IDs of a trunked system for activity. While you cannot hear conversations in this mode, it is an excellent way to determine which talk group IDs are the most active. To set the scanner to monitor IDs, hold down MON/CLR (•) until SEARCH and the channel num- ber flash. All active group IDs appear in quick succes- sion. To stop monitoring IDs, press SRC again.

Note: When you monitor IDs, any IDs you have locked out also appear.

CHANNEL ACTIVITY BARS

Your scanner displays up to 20 channel activity bars for the stored frequencies in a bank. These bars indicate the activity taking place on a trunked system. By observing these bars, you can see how many frequencies are be- ing used and generally monitor how much communica- tion traffic occurs.

Each frequency you store in a trunking bank has a corre- sponding activity bar. However, there are only 20 bars for a possible maximum of 50 frequencies. If the trunk system contains more than 20 frequencies, some bars will represent more than one frequency.

•If a bar appears steadily without any voice transmis- sion, it represents the frequency in use as the data channel.

•If a bar appears and flashes when an ID appears, the bar represents the frequency being used by the trunk system transmitter.

•If a bar appears without any voice transmission, the channel is probably being used for a telephone interconnect call or a private call, or the bar might be a locked-out ID. Your scanner does not monitor these types of calls.

•If the scanner is holding on an ID which is not being used, the other activity bars turn on and off as other groups use the system.
