All frequencies listed on this page require a FCC license when used in the United States, except the five MURS frequencies (151.82, 151.88, 151.94, 154.57, 154.6).

Color Dot/Star Itinerant and Low Power Frequencies

Many decades ago radio manufacturers adopted a color coding shceme so that radio users could easily identify which frequencies their equipment operated on.

Sometimes referred to as "bubble pack business radio" frequencies, these are typically used by low power hand held business radios. Users might include construction site operations, schools, events, fast food drive-thru intercoms, and other miscellaneous business uses.

Some of the frequencies are restricted to itinerant use and some have different power restrictions.

Three GMRS Frequencies are listed as "color dots" below. This is because businesses and other organizations could obtain GMRS licenses up until some time in the late 1970s to early 1980s when the FCC regulations changed and some radios were sold with color coded GMRS channels for business use. Presently business use of GMRS frequencies is generally not allowed.

There are other frequencies in the 450-470 MHz band that are restricted to low power operations in certain areas. See the links below the table and at the bottom of this page for detailed information.

Notes

(1) Maximum power 1 Watt.
(2) Maximum power 2 Watts.
(3) Maximum power 35 Watts.
(4) Itinerant use only.

Other frequencies may also be licensed for mobile only, low power, or itinierant use. Refer to:
- 47CFR90.35 Industrial/Business Pool Frequency Table. The numbers in the Limitations column refer to the notes in section (c) below the table.
- 47CFR90.267 Assignment and use of frequencies in the 450-470 MHz band for low power use.

Modes and emission designators used depend on the bandwidth allowed on a particular frequency. Refer to the FCC rules linked above. FM, FMN and various digital modes such as MOTOTRBO, NXDN, or P25 may be used.

Motorola Preset Frequencies

Some Motorola hand held business radios have factory preset channels. A few models are listed below. Complete frequency and tone information for some models can be found in the users manuals available on Motorola's web site.

Some of the manuals appear to contain duplicate channels and other typographical errors. If you can correct the errors please do so.

Common UHF Frequencies used by BearCom Rentals and Others

These frequencies, used either in simplex or repeater mode, are commonly used by BearCom (one of the largest radio-rental companies in the United States) for special events.

900 MHz Common Low Power Simplex Operations

936.6375 R/S / 897.6375 input
936.6625 R/S / 897.6625 input
939.9750 R/S / 900.9750 input
939.9875 R/S / 900.9875 input

Radio rental companies sometimes obtain STA (Special Temporary Authority) licenses for their customers' short term events. These can include simplex channels, temporary repeaters or temporary trunked systems. Almost any Business/Industrial Pool frequency can be used, not just the ones listed, but anywhere in the bands, including T-Band.
