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]. And please note that this is an introductory level page concentrating 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].

The Grand Canyon National Park (GRCA) competed a Phase 1 of a transition to a multi-site, simulcast P-25 system in 2010.

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):

=== '''Which radio to use''' ===
 
−
 
 
−
The current trend in public safety communications is to use digital technology. In the valley, there are analog systems, digital systems and combination systems. Also, since television's move to digital broadcasting, a new band of 700 Mhz frequencies have become available for public safety 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:

−
 
 
−
 
−
Another thing to remember is that 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. This is a factor of the scanner quality and the type of system you want to hear - 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 valley public safety trunked systems, 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 agencues, we need to know the 'system' that provide's the coverage for the area of interest. Below we have listed the system names, locations and relative coverage aras 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.

'''Talkgroups:'''
 
−
 
−
Each Agency has unique needs, and its talkgroup (channel) assignments may differ from a neighboring agency. Agencies also frequently change priorities, and talkgroup realignment may occur. For the most part, though, the dispatch talkgroups stay the same. Dispatch talkgroups are also the busiest, with much routine traffic. Many agencies use a 'hot' channel to dispatch urgent calls. We recommend including 'hot' talkgroups in you scan list.
 
−
 
−
One of the reason that area-wide systems are so popular is the ability to provide interoperability - the ability for officers from differnt departments (and on differnt 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 bank and scan them regularly. You may be surprised at what you will hear!
 
−
 
−
'''''A word about encryption or 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.''
