Radio Shack PRO-96 data to follow activity on the talkgroups you wish to monitor

Ô NOTES Ô

To receive trunking signals from a trunked radio system, you must:

•Store all the trunking control frequencies for Motorola or APCO-25 systems in one channel storage bank, or

•Store all the trunking system frequencies for EDACS in one channel storage bank, and

•Configure the channel storage bank ID list for the type of trunking system being monitored, and

•Enter ID codes into the ID memory for the bank

•For detailed trunked system programming instructions, see “Programming Trunked Systems” on Page 32 and “Storing Talkgroup IDs” on Page 38.

data to follow activity on the 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 efficiently. Instead of selecting a specific frequency to transmit on, a trunked system chooses one of several frequencies when the 2- way radio user transmits. The system automatically transmits the call on that frequency, and also sends a code that identifies that 2- way radio user’s transmission on a control channel.Ô

Your scanner lets you easily hear both the call and response transmissions for that 2-way radio user and therefore follow the entire conversation. For Motorola, APCO-25 and EDACS trunking systems, the scanner monitors the control channel between each transmission to determine active talkgroups.

Your PRO-96 automatically calculates Motorola and APCO-25 trunking system voice channel frequencies while decoding the control channel. This eliminates the need to enter all the Motorola system frequencies.
