PMR446 (Europe) - Private Mobile Radio 446 MHz, Portable Mobile Radio 446MHz 446MHz Professional Mobile Radio 446.0 MHz - 446.1 MHz (original allocation), 446.0 MHz - 446.2 MHz (current allocation). 0.5 watt 500 milliwatts TX power limit. See also: the LPD433 very short range service on 433 MHz and 434 MHz (ITU Region 1 only).

Analog and digital license-free low power radio service, similar to the 462 MHz - 467 MHz FRS and GMRS services in the United States, the 477 MHz UHF CB in Australia and New Zealand, the 448 MHz South Korean Personal Radio Service and several other UHF band license free two-way walkie-talkie radio services.

Unlike most other country-specific services, PMR446 is standardized throughout Europe, the UK and numerous other countries worldwide. 500mW power limit. CTCSS, DCS and other selective calling and squelch systems are allowed in analog mode, digital selective calling permitted in digital voice mode - talkgroups, color codes, etc.

PMR446 was originally assigned 8 analog FM voice channels from 446.0 MHz to 446.1 MHz then expanded to 16 analog/digital channels + 32 digital only voice/data channels in the 446.0 to 446.2 MHz range for a total of 48 channels.

Where the PMR446 service is authorized the 446 MHz frequency spectrum is not part of the 70cm amateur band.

PMR446 channel 1 446.00625 MHz is the de facto calling frequency. These frequencies (both analog and digital) are heavily used in urban areas throughout Europe, much like other personal radio services are in other parts of the world. In some countries, channel 8 446.09375 MHz is used as the calling frequency (with 88.5 Hz CTCSS) instead of channel 1.

Analog PMR446 and digital voice DMR Tier 1 frequencies

Digital TDMA voice (DMR) also allowed on these 16 channels - referred to as DMR Tier 1 or DPMR Tier 1 - wide band digital, 12.5 kHz bandwidth. 16 channels. Analog narrow band FM voice shared on the same 16 frequencies. In dense urbanized areas of Europe, it is quite common to hear numerous signals on most or all of the PMR446 channels.

Digital FDMA dPMR446

Digital dPMR446 uses 32 digital voice channels separated by 6.25 kHz from each other with 4-level FSK modulation at 3.6 kbit/s (3600 baud). These frequencies overlap the original 16 analog voice/digital voice frequencies and operate in the same 446.0 to 446.2 MHz frequency range of the original PMR446 service. Kenwood designates the 6.25 kHz PMR446 digital band as DPMR446 or Digital dPMR446, not to be confused with digital DMR Tier 1 (which operates on the 12.5 kHz "wideband" channels, same frequencies as the analog channels).

PMR446 Band Plan In Order Frequency 446.0 MHz - 446.2 MHz

Note the overlapping narrow band digital voice / data only 6.25 kHz channels (3.125 kHz offset) and wide band analog FM voice / digital voice 12.5 kHz channels (6.25 kHz offset).
