The new system will allow public safety users throughout the county to communicate with one another seamlessly while they carry out their respective daily missions, as well as during periods of extreme emergency and disaster. Currently, public safety professionals in the county operate with a patchwork of obsolete and unreliable radio systems in many different bands. Implementation of the new system will bring all users together onto a sturdy, trustworthy network that will serve York County deep into the 21st Century.

==Transition to 700mhz and Phase 2==
 +
In 2015, the York County Board of Commissioners, in response to the Middle Class Tax Relief and Job Creation Act of 2012 and it's associated "give-back" of the UHF-T band, voted to upgrade the county's P25 system, which went online for all county users in 2009. The upgrade will involve moving to available 700mhz P25 spectrum, and a transition of Phase 2 P25 trunking. Project 25 (P25) Phase 2 means that voice calls on the system will occur in TDMA, not FDMA modulation, essentially allowing two (or more) voice calls to occur simultaneously on the same frequency. This reduces the total number of frequencies needed to maintain necessary capacity on the system.  
  
York's system will employ a series twenty-two tower sites encompassing four simulcast zones and a single-site zone to provide reliable portable radio coverage in all reaches of the county. Portable and mobile radio units are equipped with the ProRoam feature, allowing the radio to transition between the five coverage zones with no input from the user, ensuring that the radio will be registered with the tower site providing the best possible signal to that radio.
+
The upgrade involves the replacement of RF equipment and antennas at every tower facility, and the replacement of all end user (subscriber) terminal radios in the field. During the project, the microwave backbone is being upgraded, a new tower site is being added (Brogue), and an existing tower structure is being replaced (Fox43) due to it's age. Additionally, the Fulton site, which is stand-alone on the 500mhz system, will be absorbed as part of the south simulcast on the 700mhz system, eliminating the need for field users to manually select the tower when their location requires.
  
While some tower sites are situated on existing towers or structures, a handful of new towers have been erected. Also, new hardened, climate-controlled shelter buildings have been built to house the system's electronics. The simulcast timing is controlled by redundant GPS clocks located at each simulcast site. A microwave backbone will connect system sites to one another and to the control stations at the newly constructed 911 center and the back-up facility.
+
In the database, you will notice that 700mhz sites have been added. The 700mhz system will run concurrently with the 500mhz system as agencies are transitioned to the newer system. As agencies are loaded, their talk groups will be activated on the new system. Talk groups which are active on the new system will remain active on the old system until cutover is compete, and voice calls will be carried on both systems. If you are monitoring a call on the 700mhz system, it will be using phase 2 modulation, and you would need a phase 2-capable scanner to hear the call.  
  
 +
At this point, talk groups are unchanged, and will transfer one-for-one to the new system. However, it is rumored that the fire/EMS talk group plan and dispatcher deployment may change as cutover nears for that user group.
  
                                        '''''Central Zone'''''
 
  
The most robust of the simulcasts, this zone employs nine tower sites and utilizes fourteen repeater channels to provide coverage for the central mass of the county, which includes Metro York, Springettsbury, Manchester, West Manchester, Spring Garden, Spry, Dallastown and Red Lion.

A microwave backbone will connect system sites to one another and to the control stations at the newly constructed 911 center and the back-up facility.
  
                                        '''''North Zone'''''
 
 
Covering the northern areas of the county, the North Zone utilizes ten repeater channels from four tower sites, and provides service for Dillsburg, Yocumtown, Lake Pinchot, and Fairview.
 
 
'''Tower Sites:''' Dillsburg, Ramsey Hill, Reesers Summit, and Yocumtown
 
 
'''Frequencies:''' 500.48750, 500.53750, 500.81250, 500.91250, 501.06250, 501.31250, 501.33750 501.56250, 501.58750, 501.81250
 
 
 
                                        '''''West Zone'''''
 
 
The West simulcast will provide coverage for the Hanover area, as well as Spring Grove, West Manheim, Lineboro, and Heidelburg/Porters Sidling. The zone will simulcast from two towers, and employ ten repeater channels.
 
 
'''Tower Sites:''' Iron Ridge (Pigeon Hills), Spring Grove
 
 
'''Frequencies:''' 500.63750, 500.68750, 500.93750, 501.08750, 501.38750, 501.46250, 501.73750, 501.78750, 501.93750, 502.03750
 
 
 
                                        '''''South Zone'''''
 
Providing signal to the ever-growing communities of southern York County, the South Zone will take advantage of two towers constructed by the Commonwealth for the state wide radio system, along with four other tower sites. This zone will provide adequate capacity with it's ten repeater channels.
 
 
'''Tower Sites:''' Crossroads (East Hopewell Township Building), Gatchelville (York 89),Lower Chanceford, Glen Rock, Shrewsbury (York 94), and Stewartstown Water Tank
 
 
'''Frequencies:''' 500.33750, 500.46250, 500.58750, 500.73750, 500.88750, 500.98750, 501.18750, 501.26250, 501.43750, 501.48750
 
 
 
                                        '''''Fulton Zone'''''
 
A single tower site, this system employs three repeater channels to provide coverage of the often troublesome Susquehanna River proper in extreme southeast York County. Located on the Lancaster County side of the river, it provides a clear shot upstream.
 
 
'''Frequencies:''' 502.01250, 502.36250, 502.53750
 
 
 
                                        '''''Talk Groups'''''
 
The flexibility of a trunked radio system allows York County to incorporate a near-endless number of talk groups. Previously, York County's law enforcement, fire, and EMS responders have been congested into a very small number of radio channels. For instance, all EMS users countywide were using a single radio channel for dispatch and operations. Fire users were in the same boat. Police users had far too few channels for their routine operations, and NO ability to expand in the event of a major incident. The new system provides each response discipline with almost ten times the talk group capacity as the previous systems.
 
 
Each police dispatch sector is provided a main dispatch group, three tactical groups, a car-to-car group, and a supervisor group. Additional police dispatch sectors have been added to reduce the extreme congestion experienced on the previous police dispatch system, specifically those police agencies in and around the York City metro area. Law enforcement agencies who previously had limited or no radio capabilities (such as District Attorney investigators) now have dedicated talk groups.
 
 
Emergency medical service users will enjoy two operational talk groups and two tactical talk groups, as well as the ability to access fire operation talk groups for those instances where EMS units respond on fire-related calls. Additionally, each hospital in the county has been assigned two talk groups for EMS-to-hospital communications.
 
  
Fire departments will notice expanded talk group capabilities as well. Previously, the county's nearly seventy fire departments had only one radio channel on which to communicate with the fire dispatcher, and five low-power channels to accommodate fire ground communications. The new system will give fire departments four talk groups for routine unit-to-dispatcher communications, and an additional ten talk groups for fire ground operations, ensuring that each working incident will retain it's own dedicated talk group. Having fire ground communications occur on system talk groups adds the safety factor of enabling a dispatcher to monitor the fire ground radio traffic, and also allows units responding from a distance to receive updates and orders from the fire ground commander via portable radio.

*[[York County Talkgroup Description]]
  
The county's emergency management agency (which operates the Hazardous Materials Response Team) has mirrored it's previous channel plan on the new system, including EMA communications, as well as Haz Mat operations and entry groups. Two additional talk groups allow the county's emergency management and 911 officials to directly and instantly communicate with officials at the Three Mile Island and Peach Bottom nuclear power stations.

Interagency and interoperability solutions have been built into the talk group plan as well. Three interagency talk groups enable police, fire, and EMS users to communicate with one another for routine and emergency matters. An additional four special event talk groups enable all county users to communicate during multi-discipline events.
 
  
Additionally, the county will be able to communicate with non-system users via microwave and VOIP patches made to mutual aid talk groups on the system. The plan is to enable this level of interoperability to each non-system user bordering or transiting York County, including Cumberland County, Dauphin County, Lancaster County, Adams County, Harford County, Baltimore County, Carroll County, PA State Police, and PA Turnpike Authority.
 
  
                                        '''''Paging'''''
 
York County's legacy paging includes one low band frequency and two UHF channels to disseminate calls to public safety workers. Upon completion of the new system, a single channel UHF POCSAG alphanumeric paging system will be deployed, eventually replacing the legacy paging entirely. Operating on a frequency of 453.600, the new paging system will simulcast from 18 of the county's 22 tower sites, providing reliable service to all first responders county-wide.
 
  
  
                                        '''''Conventional'''''
 
It is anticipated that York County will maintain very few conventional channels once cut-over to the new digital trunked system is complete. FMARS (Fire Mutual Aid Radio System, 154.280mhz) and NLEEF (National Law Enforcement Emergency Frequency, more often referred to simply as "National" 155.475mhz) base stations will be maintained for inter-county communications. Portable, mobile, and base station radios have been programmed with nationwide UHF interoperability frequencies (UTACs) in the simplex mode to accommodate both interoperability needs as well as the need for talk-around functions.
