While this page is designed to help the new hobbyist, or a traveler unfamiliar with the Phoenix area, to get started listening to one of the fastest growing areas of the country, we do expect the user to have a basic understanding of [http://wiki.radioreference.com/index.php/Category:RR_Glossary radio terminology].

The Grand Canyon National Park (GRCA) competed a Phase 1 of a transition to a multi-site, simulcast P-25 system in 2010.  
  
And please note that this is an introductory level page concentrating on basic public safety monitirng for the valley's trunked systems. There are more detailed sites available for the more experienced listener. If you want more detail on the valley's systems and users, may we respectfully suggest you consult [http://radioreference.com  Radio Reference], or purchase the [http://www.scannerstuff.com/swfd.htm  Southwest Frequency Directory].

There are really only four major systems in the metropolitan Phoenix area where a radio hobbyist can hear the majority of police and fire traffic. Here is a list of the systems and their subscribers (users):
 
 
 
'''Topaz Regional Wireless Cooperative (TRWC)'''
 
* Mesa
 
* Apache Junction
 
* Gilbert
 
* Queen Creek
 
* Apache Junction Fire District.
 
 
 
'''Regional Wireless Cooperative (RWC)'''
 
* Buckeye
 
* El Mirage
 
* Goodyear
 
* Peoria
 
* Phoenix
 
* Surprise
 
* Tempe
 
* Chandler Fire
 
* Daisy Mountain Fire Department
 
* Guadalupe Fire Department
 
* Maricopa Fire Department
 
* Sun City Fire Department
 
* Sun City West Fire Department
 
* Sun Lakes Fire Department
 
* Scottsdale (pending)
 
* Paradise Valley (pending)
 
* Tolleson (pending)
 
 
 
'''City of Glendale'''
 
* Avondale
 
* Glendale
 
 
'''Maricopa County Radio System'''
 
* Maricopa County
 
* Scottsdale
 
* Paradise Valley
 
 
 
=== '''Which radio to use''' ===
 
 
 
The current trend in public safety communications is to use digital technology. Also, since television's move to digital broadcasting, a new band of 700 Mhz frequencies have become available for public safety systems.
 
 
 
In the valley, there are analog systems, digital systems and combination systems. For instance, the Maricopa County system combines analog and digital communications on an 800 Mhz system. Phoenix, Glendale and Mesa systems are fully digital and use both 700 and 800 Mhz frequencies. Small systems like Chandler are only analog.
 
 
 
Most 'trunking' scanners can track the 800 Mhz analog trunking systems. To track digital systems a P25 compatible scanner is required; to track the new 700 Mhz trunked systems, a 700 Mhz capable radio is needed.
 
 
 
We do not recommend any particular brand of scanner. We '''do''' recomend that you research your purchase carefully to ensure that you can hear the systems you want to hear. Here are links to the more popular scanners:

*[http://www.greamerica.com/ GRE Company Website]
 
 
 
*[http://wiki.radioreference.com/index.php/Radio_Shack_Scanners Radio Reference Radio Shack Pro-106 and Pro-197 wiki]

*[http://uniden.com/products/index.cfm?cat=scanners Uniden Company Website]
 
 
 
A final note: Scanners are not built to the same standards as professional radios and you may not be able to clearly hear what you want to hear.
 
 
 
==='''Systems and Sites'''===
 
 
 
We refer a lot to systems and sites. Simply speaking, a '''system''' consists of one or more '''sites'''.
 
 
 
A site is a specific transmitter location with a set of frequencies assigned to it. Most wide area systems have many sites.  When all sites in a system use the same frequencies, the system essential becomes one site - it is only necessary to program in one set of frequencies to monitor that entire system. When each site in a system has its own set of different frequencies, you must enter each site's frequencies seperately to monitor that system.
 
 
A '''simulcast system''' transmits the same traffic on all sites in the system. The valley's systems uses simulcast technology that some scanners have difficulty tracking. This is usually because of the relative positions of the scanner and the site you are monitoring. Sometimes moving your radio's location, adjusting or changing antennas, or adding attenuation to the frequency may help (see your radio's user guide). For more details on reception issues see the appropriate radio discussion forums at [http://forums.radioreference.com/ Radio Reference] or vist [http://groups.yahoo.com/ Yahoo groups] for your area of interest. 
 
 
 
=== '''What to program''' ===
 
 
 
Most trunked scanners require at least the data frequency (the 'control channel') to be programmed for each site. Some older scanners require all the voice frequencies to be entered as well. To listen to just valley public safety traffic(and not all users on a system) you also need the correct voice channels - known as 'talkgroups.' A complete list of frequencies and talkgroups can be found at the links on the bottom of this page.
 
 
 
For the purposes of monitoring the valley's public safety agencies, you need to know the system that provides the coverage for your area of interest. We have included a list of system names, locations and relative coverage areas to allow you to decide what systems you should program to hear your areas of interest. At present, not all systems are linked to each other. (In fact, there are plans to 'unlink' the TRWC and the RWC.) So, a hobbyist would need to program all of the following sites to hear the majority of public safety traffic in the valley.

*[[National Incident Radio Support Cache]] - These frequencies are also used for active fire operations.
  
'''Talkgroups'''
 
 
Each Agency on a sytem has its unique talkgroup (channel) assignments. Dispatch talkgroups are the busiest, with much routine traffic. Tactical talkgroups can be used for small incidents or to coordinate large events. Many agencies use a 'hot' channel to dispatch urgent calls. We recommend including 'hot' talkgroups in your scan list.
 
 
One of the reason that area-wide systems are so popular is the ability to provide interoperability - the ability for users from different agencies (and even on different systems) to communicate with each other at the scene of an incident, without relaying through a third party. Interoperabilty (mutual aid) channels can be very exiting, but there use is sporadic. A good practice is to program these talkgroups in their own folder or group and scan them regularly. You may be surprised at what you will hear!
 
 
'''''A word about encryption and scrambling''': You may also notice that some talkgroups are scrambled and you will not be able to understand the traffic on those channels. (These talkgroups are marked with the letter 'E' on the Radio Reference pages listed below.) Due to the nature of digital encryption, specific technical information is needed to convert the scrambled signal to clear speech - and that information is only released to those individuals or agencies that need it. No scanner on the market today can be converted to monitor digital encrypted communications.''
