Due to changes in my personal and professional responsibilities, I no longer have the time to dedicate to maintaining this web site which I once did, and which it truly requires.

I will leave the site up as-is with little or no maintenance because some of the information may be useful for some time yet, however that usefulness is presently somewhat limited and will further diminish with time. Other sites may now or soon provide a better resource for comparable data.

For all the municipalities or groups listed above, there is a table of the frequencies and a brief description of how they are used. The first field is the channel name and/or usage, the second column is the radio frequency, the third column is the type (R=repeater, B=base, M=mobile), and the fourth column is the squelch or modulation type (CSq = carrier squelch). A two-digit number in the last field represents an Logic Trunked Radio (LTR) Logical Channel Number (LCN) which is helpful for programming; any known associated talkgroups will be listed further down in the same table. A number with a "$" prefix in the final column represents the Network Access Code (NAC) for APCO P-25 digital. "DMR" in the last column indicates Digital Mobile Radio-format digital, of which MotoTRBO is one brand example.

Tables or portions of tables containing trunked talkgroup data will have headers if needed to clarify the information represented. Modes may be "Ana" (analog), "Digi" (digital), or "Enc" (digital encrypted); digital versus encrypted is not always known in EDACS since neither can be decoded by consumer scanners.

It is intended for all public safety (police/fire/EMS/OEM) and government (roads dept/building dept/schools) channels to be listed here, plus most business repeaters and other channels which may be of particular interest. Many business channels have intentionally been omitted because researching and processing them all would be impractical. If you are searching for one not listed, try the FCC database or check if they are using an undentified talkgroup on one of the SMRs. If you are searching for additional tactical channels used by a business which has repeaters shown, try the master frequency lists. If you find or know of anything which is not listed here, please e-mail them to the author so that others may benefit.

Businesses should be listed under the municipality they are principally located in. County-wide busineses like utilities may be listed under the County Other section or with the municipality in which the main transmitter is located.

Standard and regional channels have been omitted from this page for brevity and can be found on the General Mercer/ Middlesex/ Somerset County Channels page.

Somerset County currently operates two trunked radio systems: the legacy Motorola system and a P25 system which will eventually replace the Motorola system. The P25 system is further divided into a UHF zone and a 700 MHz zone.

Talkgroup assignments are about the same between the two systems so individual channel entries on this page will note the old and new talkgroup numbers -- if a channel is not yet in regular use then the anticipated new talkgroup ID will be in parentheses; if a channel has completely moved to the new system then the old talkgroup ID will be struck through. Analog notation only applies to the old system, P25 systems are 100% digital (though it can be either clear or encrypted). Each talkgroup entry also notes the Z (zone) and P (P25 phase). A P entry of 2 means that a scanner must be capable of APCO P25 Phase 2 in order to receive the signal; this is generally limited to only the newest models of digital scanner. Franklin Township's trunked system is treated separately on this web page, for simplicity's sake. For the most part Franklin's talkgroups stay on Franklin's zone and the county's talkgroups stay on the county's zones.

The P25 system ID is BEE00-457, the county-wide simulcast UHF site is 001-003, and the county-wide simulcast 700MHz site is 01-004. Programming it as type P25 Auto is recommended but if manual tables are required, use the following: Base5=470.0000 Step5=12.5 Offset5=20480; Base6=500.0000 Step6=12.5 Offset6=24576; Base7=502.0000 Step7=12.5 Offset7=28672. As users migrate from the old system to the new system, repeaters are likely to gradually move with them.

The legacy Motorola system ID is 8A27 and the county-wide simulcast side is 1 (Franklin piggy-backs their zone as Site 2 on this system). There are three configuration tables which must be programmed into scanners: Base1=500.3375, Offset1=380, Step1=25.0; Base2=501.9125, Offset2=430, Step2=25.0; Base3=502.5125, Offset3=450, Step3=25.0. If your scanner only supports one configuration then use 502.5125/450/25.0 and know that you will receive only about 80% of the communications.

Each zone (excluding Franklin's) is simulcast countywide. Transmitter sites, according to the FCC licenses, vary a bit from zone to zone, and additional receive-only sites may be in use. Approved transmitter sites for the 700MHz zone are:

Please note that talkgroups may pop between zones with seeming randomness -- this is because talkgroups will come live when a radio on that system tunes to it. For example, Fire Region 6 (including Montgomery) may not normally come over the P25 UHF zone but it will when a Montgomery PD radio which is working on that zone tunes to it. Hillsborough PD's channel may only come over the P25 700 zone until a Manville PD radio tunes to it on the P25 UHF zone or a Hillsborough Fire radio tunes to it on the Motorola zone. For that reason the zone/talkgroup arrangement is very fluid and you may be best scanning as many of the three zones as your scanner will reasonably permit.

Some notes on the unidentified/unconfirmed talkgroups: 01616/101 is suspected to be a talkgroup which will open up any radio, a system-wide announcement channel. A series of talkgroups are in the numeric vicinity of the interop talkgroups; they may be for other services' interops and/or events; Piscataway PD used loaner portables on 15088 when their system was briefly taken down for maintenance in August 2006. 32304 once had technicians installing or maintaining security cameras apparently at the courthouse.

Somerset County has gradually taken over dispatch of most in-county fire departments and emergency medical services and consolidated their communications in conjunction with the switch-over to the trunked system. Some alerting is still done on Fire-High, JEMS-1, 155.31, and other channels but most pages from county are multicast over the UHF county-wide alerting channel; some agencies are paged on only this UHF channel now with the old channels completely abandoned. Other legacy channels may be consolidated as a part of this process; one example is that county took over Montgomery's fire and EMS dispatching in the first quarter of 2006, and Mercer County eventually changed too so the 82.5 PL on fire-high is no longer used; similarly the 110.9 tone used for Hillsborough and Branchburg has been switched to 100.0.

County OEM, including the HazMat team, operates entirely on the trunked system.

The table on the right lists all the station numbers for Somerset County fire (##F) and EMS (##R) stations; some now-defunct stations have been included to fill in gaps in the current numbering. Some stations are physically located outside Somerset County but are primary responders in and so have Somerset County numbers. "Municipality" is meant to indicate the Somerset County town the station is a primary responder for -- out-of-county towns and mutual-aid towns are not included. "Dist" indicates which fire district (if any) the company is a part of, because some areas are dispatched by district. NJFFS Section A7 is included for the sake of providing a link; they serve the area but do not in any way fall under the auspices of Somerset County.

Fire regions are organized as listed below. This does not necessarily reflect what channel(s) are used for routine operations; see individual municipalities for that information.
Region 1
Bedminster, Bernards, Bernardsville, Far Hills, Peapack-Gladstone
Region 2
Branchburg, Bridgewater
Region 3

Region 4
Bound Brook, Manville, Raritan, Somerville, South Bound Brook
Region 5
Franklin, Millstone
Region 6
Hillsborough, Montgomery, Rocky Hill

The standardized numbering system formerly used by the county fire and BLS agencies has been updated and modified to use plan English to describe the unit kind and, when necessary, type.

Somerset County dispatches Somerset Medical Center's ALS and BLS units; paging is on the UHF channel and dispatch is on EMS Dispatch 1. SMC-EMS is the sole (assigned) user of EMS Ops-4 for coordination and transport units operation. RWJUH medic units (MedRescue #) are still primary responders for parts of Somerset County and are dispatched by MedCentral (see Middlesex County for more info). ALS from from Hunterdon and Mercer Counties occasionally provide mutual aid.

Local EMS agencies use Region 1 dispatch in the north and Region 2 dispatch in the south. Ops channels 1-3 are used as indicated per town.

Somerset County ARES is a part of the North NJ ARES Section.

Raritan Valley Community College has a few conventional channels. In 2013 the county's DPW, transportation, and recycling services moved to the state 700MHz system ("NJ Interoperability Communication System / NJICS"), possibly to free up capacity for municipal users and during the transition from the Motorola system to the P25 system. Other county users are believed to remain on the county's own system(s), as have all former municipal users.

10320, 10352, and 10384 may be county services event talkgroups; the 4H fairs in 2005 and 2006 have been run using OEM loaner radios mostly on 10352 and a little on 10320.

Bernards Township's Police Department is dispatched by Somerset County on its own high-band repeater.

Bernards Township fire companies, including the Basking Ridge Fire Company #1 and the Liberty Corner Fire Company, are dispatched on a high-band repeater by Somerset County. Two high-band repeaters have been licensed, one by each fire company. It appears that the township assisted both with the licensure, and control points for both are at the police station (LCFC's license shows the repeater at their station). It is unclear what the intent of these channels is, whether to be main dispatch or a secondary coordination/ops channel, and whether they are presently in use.

EMS is provided to Bernards Township by the Basking Ridge Fire Company #1 First Aid Squad and the Liberty Corner First Aid Squad. The squads are dispatched by Somerset County on the same high-band repeater as the fire companies.

Bernards municipal communications were on a low-band channel. It is possible the unidentified high-band repeater is for them, so that they're on the same band as police and emergency services.

Bernardsville Borough's Police Department is self-dispatched on low-band. It is understood that the county's trunked system was tested but found to have unacceptable coverage gaps in Bernardsville; coverage may improve with the new system and/or with other system improvements, so it is possible the police department will switch in the future.

The Bernardsville Fire Company #1 & First Aid Squad is dispatched by county; alerting is on the county-wide UHF channel and dispatch on Fire and EMS Regions 1. The tactical/relay channels may be for mobile extenders.

Bernardsville Borough DPW operates on a talkgroup on the county's system.

Bridgewater Township's Police Department is self-dispatched on a high-band repeater. F-2 through F-4 have not been confirmed (in fact, 3 and 4 do not appear to be licensed), but are reportedly for tactical communications; F-6 is an alternate channel for the PD, the DPW channel. As of late 2013 the dispatch channel is patched into a talkgroup on the county's P25 system (700MHz zone); this may be in preparation for a move to that system.

Bridgewater's fire companies are arranged as follows:

Fire District One
43-Fire Martinsville Fire Company #2
Alerted on the countywide UHF channel and operates on its own UHF channel.
Fire District Two
21-Fire Bradley Gardens Fire Department
Alerted and operates on its own UHF channel.
Fire District Three
24-Fire Country Hills Volunteer Fire Company
34-Fire Green Knoll Volunteer Fire Company
49-Fire North Branch Volunteer Fire Company
Alerted and operates on the UHF repeater. Note that 24 and 49 also respond as primary into Branchburg but use the county's trunked system for those calls.
Fire District Four
30-Fire Finderne Engine Company #1
Alerted on Fire-High and operates on Fire Region 2.

Bridgewater dispatches BLS agencies for the township. Bound Brook, Bradley Gardens, and Finderne are paged on 155.310. Daytime coverage for them is provided by Somerset Medical Center EMS (dispatched by county). Martinsville and Green Knoll are alerted and dispatched on their own channel, and usually have their own daytime crew.

Some but very little communication has been heard on the DPW channel as of January 2014. It is unclear whether they do not use the radio a lot or if communication has moved to another channel.

Far Hills Borough

Far Hills Borough's Police Department (07-## units) is dispatched by county and uses Police Region 1 channels.

See Bedminster Township for emergency services serving Far Hills.

Franklin Township operates a mixed-mode trunked radio system, which is actually a mostly self-contained zone piggy-backed off the county's Motorola system. Thus Franklin's system ID is 8A27 and site is 2 (county is Sites 1, 3, & 4). Frequencies are shown at left; there are two configurations for trunk-tracking scanners: Base1= 471.0000, Offset1= 380, Step1= 12.5; Base2= 476.2500, Offset2= 540, Step2= 12.5. Since the frequencies and configurations are different than county's, and since talkgroups mostly do not roam between the sites, it may be best to program this into scanners as a completely separate system instead of combined with the county's site.

The Franklin Police Department moved all their operations to the trunked system on 7/01/04, and all police talkgroups noted to date have been encrypted. The old, conventional infrastructure and ability on it has been maintained and used as a backup to the trunked system. The old police identifiers (possibly still in use) were: police cars= 800 series; chief= 2000; captain= 3000; lieutenant= 4000; sergeant= 5000; detective= 6000; beat officer= 7000; special officer= 8000; dispatcher= 9600.

Franklin PD has occasionally used old PD-1 for operations when maintenance is required on the trunked system. The department also used the analog "911 Access" talkgroup for routine dispatch around 10/20-22/06 for an unknown reason; the encrypted dispatch talkgroup and others were used at the same time for something else.

The Franklin fire companies are divided up as follows:
Fire District One (north)
26-Fire Elizabeth Avenue Fire Company
28-Fire Millstone Valley Fire Department
44-Fire Middlebush Volunteer Fire Department
56-Fire Somerset Volunteer Fire & Rescue Company #1
Fire District Two (south/central)
31-Fire Franklin Park Volunteer Fire Company
35-Fire Griggstown Volunteer Fire Company
41-Fire Little Rocky Hill Volunteer Fire Company
Fire District Three (north/east)
25-Fire Community Volunteer Fire Company #1
27-Fire East Franklin Fire Company
Fire District Four (south - Kingston)
39-Fire Kingston Volunteer Fire Company #1

The Franklin fire companies are dispatched by county; alerting is on Fire-High and dispatch is on the district's talkgroup (Station 39 uses District 2). Districts 1, 2, and 3 each set up a multicast of the dispatch talkgroup over their old VHF dispatch frequency. District 1 has applied for a UHF repeater and the FCC license grant is pending. District 2 has set up a UHF repeater which multicasts District 2 talkgroup. District 3 has received a FCC license for a UHF repeater however its use has not been observed. East Franklin's chief has a long-time UHF repeater which seems to be used for unofficial talk-around communications by fire company members. Kingston may also use talkgroups on South Brunswick's trunked system for internal communication.

Franklin (as "Franklin PD") continues to dispatch all squads itself. EMFAS (52) and FSFAS (71) are alerted by Franklin on JEMS-1, Kendall Park and Kingston Squads are alerted by South Brunswick (Middlesex County) on its emergency service paging channel, and Rocky Hill is paged by County on Fire-High. All five squads, RWJUH-SPUH ALS, RWJUH-SPUH BLS, and SMC ALS all communicate with Franklin on the trunked system. Since Rural-Metro left NJ in 2006, around-the-clock EMS coverage has been supplemented by Ambulance 782 (primary) and others as needed from RWJUH EMS (or Rutgers EMS). Its dispatch is by MedCentral though it also contacts Franklin on Franklin's EMS channel.

Animal control and the construction code department joined the system in 2005 and went digital in August 2006. The Health Department joined in August 2006. Public Works began using it in the first quarter of 2006. The Department of Fire Prevention had access to it in the second quarter of 2006, but didn't start using it in earnest until they went digital in August (Township Main Analog is still their F-2).

This is a list of Specialized Mobile Radio (SMR) systems known of in Somerset County. These are basically radio channels for rent, an alternative to Nextel (and there long before Nextel existed). Unless noted otherwise all use LTR trunking; TGIDs are not yet available.

It is possible that a business you are searching for is using an SMR based outside the limits of Somerset County, and it is possible that some of the SMR sites listed here are part of a larger network for wider coverage. There are too many sites outside Mercer to cover on this page; to learn more about a network, search the FCC database for other licenses under the same provider. There is information similar to this for Mercer and Middlesex Counties on their respective pages.
