Trunking

Ô NOTE Ô

•You can scan only one type of trunked frequency, either EDACS or Motorola in a bank at one time. You can, however, mix conventional channels and frequencies in a bank.

•If you are programming trunked frequencies for Motorola Type I and hybrid systems, you must first program the fleet map (see “Programming Fleet Maps” on Page 60).

•If you are programming frequencies for an EDACS system you must store them in the Logical Channel Number order (usually listed as LCN#). For example, LCN1 would go into channel 01 for the current bank, and LCN2 would go into channel 02.

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.

Your scanner lets you easily hear both the call and response transmissions for that 2-way radio user and therefore follow the conversation. For EDACS and Motorola (above 406 MHz range), the scanner monitors the control channel between each transmission to identify talk groups.

SETTING SQUELCH FOR THE TRUNKING MODE

Your scanner automatically mutes the audio during trunk scanning when it decodes control channel data. However, we recommend you turn SQUELCH clockwise and leave it set to a point just after the hissing sound stops. This lets the scanner quickly acquire the data channel.

PROGRAMMING

TRUNKING FREQUENCIES

You program trunking frequencies the same as non-trunked frequencies, except that you must store the appropriate mode (MOT or ED) with each frequency. Ô

Follow these steps to program trunked frequencies:
