ˆTrunking Operation

The scanner tracks transmissions that use the Motorola Type I and Type II (such as Smartnet and Privacy Plus) and hybrid ana- log trunking systems, plus GE/Ericsson (EDACS) type systems extensively used in many communication systems.

Trunking systems allocate a few frequencies to many different users. When the mobile unit transmits a signal, one frequency is cho- sen from among the allocated frequencies in that trunking system. The user's ID talk group is sent with the signal.

To receive trunking signals, you must store all the trunking control frequencies for Motor- ola systems or all the trunking group fre- quencies for EDACS in one bank (see “Storing Known Frequencies into Channels” on Page 15) and input ID codes in the ID memory (see “Storing Talk Group IDs” on Page 35).

Your PRO-2053 automatically calculates Mo- torola voice channel frequencies when it de- codes the control channel. This eliminates the need to enter all of the Motorola group frequencies, unless you do not know which frequencies are the controls. If you are un- sure which frequencies act as the controls, you must enter all the system frequencies. Since the control channels are subject to change depending on the day of the week, enter all the control frequencies in the same

bank. (Refer to the enclosed Trunking Guide.)

The scanner displays the control channel memory location on the top line, the received channel with VC (voice channel) on the sec- ond line, and the bank and control channel memory location number on the third line. The display shows the Motorola ID number on the bottom line when the scanner de- codes the Motorola control channel and finds the voice channel.

Important: To listen to the transmission, the programmed channel’s mode must be the same as the trunking channel (MOT, or ED).

When an ID code is received, the ID list for the bank is searched, and if found, the text name stored for the ID appears. If not found, scanning resumes immediately unless the bank is in open trunking mode.

Note: There might be more than one talk group transmitting at a time in some Motoro- la trunking systems. If you set the scanner to manually tune in Motorola trunking mode, you will hear the talk group on that channel, but the display will alternate between all ac- tive IDs.

Trunking group frequencies are included in the supplied Trunking Guide. Frequency fleet map and talk group information is also widely
