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.

Note: All lists contain the same information, and are approximately 2.3MB each. All were updated Monday 1 February 2010.
These lists extensively cover local, county, and state public safety and other governmental users for Mercer, Middlesex, and Somerset counties in New Jersey, plus some commercial frequencies for that area, and some federal agencies. This is the raw information upon which the Mercer County, Middlesex County, and Somerset County pages are based. Those other pages offer more in the way of an explanation for each channel, on a municipality- by- municipality basis.
The data contained herein was obtained from a variety of sources, not the least of which was the various online FCC databases, and e-mail from enthousiasts like you. It was compiled in Probe 4/5/6/7, software for computer-controlled scanners, exported to a spreadsheet as a Database file, and exported from there as a space-delimited ASCII text file. You should be able to import the data I provide in a similar, but backwards, method. In addition, a DBF version of it (Microsoft Excel-compatible) is vailable in the Program Files section of this web site.
The data has been left as raw text, to keep the file size as small as possible, to facilitate exportation, and to enable the "Find in Page" (or equivalent) function of popular browsers.
Extensive use of abbreviations and codes are used in the database. Please see the appendicies for information pertaining to that:
The FCC Reports being the primary source of information for this data, it resembles their formatting. Following are the data fields for each record.
Frequency, in MHz. My database software doesn't like some of the newer splits, so when necessary they're rounded off and listed exactly at the end of the name field. Some frequencies are out of the range of the software; the frequency included is the closest the software will accept and the exact licensed frequency is provided in the name field.
FCC-assigned Callsign. There may be multiple licenses for a single channel, and the user may use an identifier not officially licensed. An asterisk (*) following denotes a pending, cancelled, or expired license (see the Trasmitter Address field for an explanation); a slash (/) denotes a special condition (i.e. no license, too many licenses to list, etc.).
Squelch method for NFM-modulated signals. Blank value means unknown; a number including a decimal is CTCSS (PL) tone, a number without a decimal is a DCS (DPL) code. 1.0 denotes carrier squelch is confirmed.
Mode: 'A' is Amplitude Modulation, 'N' is Narrow-Band Frequency Modulation, 'W' is Wide-Band Frequency Modulation.
Name of user and use of channel. The licensee is not always provided; for example a fire company may license the frequencies but they will be listed as the municipality for convenience of sorting.
The licensed location of the transmitter, not necessarily the same as the mailing address, or the address of the control point. Please note that usage does not always comply with the license. This field is not sort criteria, so it may also have notes like when the license expired.
City component of the transmitter location. This is as licensed by the FCC; applicants have made many mistakes, which generally have not been corrected here.
State and County component of the transmitter location. While applicants have made mistakes here as well, they have been corrected (when caught) noticed because this is sort criteria in certain instances.
This field was intended to be for the State (now located within the County field), but has been replaced by a date code indicating when the frequency, squelch, and usage data was last verified against reality. The first digit represents the last digit of the calendar year; the second digit represents the month (8A=January 1998, 3G=July 2003, 5L=November 2005, etc.). XO indicates usage ceased before I began tracking the last verified date; and XS indicates a standard channel like CB or GMRS, which doesn't require periodic confirmation.
Lattitude of transmitter, measured in degrees (North), minutes, seconds (DDMMSS). This value is omitted for portable and mobile transmitters, and uses data provided in the license (may be inaccurate).
Longitude of transmitter, measured in degrees (West), minutes, seconds (DDDMMSS). This value is also omitted for portable and mobile transmitters and also uses data in the FCC license (may be inaccurate).
Radio Service, as listed in the license. This does not necessarily reflect the actual usage, in whole or part. For a list of the Radio Service Codes, see the FCC site for the most current.
