Recently while I have been listening, I heard the dispatcher say that all units need to switch to zone 12 channel one. Can anyone clarify what she is talking about?

Zones

Hi there,

While I do not know the specifics of what system/agency you are referring to, here goes.
Many models of Motorola radios, both trunked and conventional, use a terms such as zone and mode to organize "channels." The concept of "zone" on such radios can be thought of as being like a "bank" on a scanner. Motorolas usually refer to channels as "modes" so someone might say zone 1, mode 2, for example. Which would be put the channel switch on "2" while selecting Zone /bank 1.

Zones can be used to organize different radio systems on which a given radio might communicate, or simply different repeater sites falling under the same trunked system. For example, if the system is Type II, but not "smartzone" (which enables automatic switching between repeater sites), a radio might be programmed with a few different zones, one for each location that the user might be operating in. In this case, the channels/modes within the zones might well be duplicates of each other (e.g. the same talkgroups).

Hope this helps!

Jean

Under the trunking system each primary dispatch area is known as a Zone. For instance the Davis area is a zone, the Weber area is a zone, and in the Salt Lake area the UHP, SLPD and the SLSO each have their own zones, and so on. UDOT also has its own zones. The mobile officer/Trooper/firefighter can talk across agency boundaries by dialing up the correct zone on their radio. This ability was extremely useful in the recent shooting at the Trolley Square Mall.

Occasionally, if their zone is undergoing some type of repair that would take their zone off of the air, a dispatch area (zone) will be given permission, or told by the radio engineers to use another zone while the repairs are being made or circumstances corrected.

I cannot tell you, however, which zone number belongs to which area.
