Motorola TA288 PMR446 licence-free radio Motorola TLKR T40 radio tuned to PMR channel 1. PMR446 (Private Mobile Radio, 446 MHz) is a licence-exempt service or UHF CB in the UHF radio frequency band, as personal radio service or citizens band radio, and is available for business and personal use in most countries throughout the European Union, [1] Malaysia, [2] and Singapore.
The term PMR is often used by the public and magazine publishing to refer to the low power (500 milliwatt) PMR446 license exempt radio systems that consist of sixteen FM frequencies between 446.00625 and 446.19375 MHz for analog FM and thirty-two FDMA (digital) channels between 446.003125 and 446.196875 MHz. These are used for personal or ...
All three of the PMR446 channel plans occupy the same European-harmonized 446.0 MHz to 446.2 MHz frequency band. One cannot legally use the FRS radio in Europe or PMR446 in the U.S. The 446 MHz band is allocated to amateur radio in the United States.
This includes a new UHF PMR 446 MHz allocation: an eight-channel analog Personal Mobile Radio 446 MHz (Analog PMR446) with frequencies from 446.00625 to 446.09375 MHz (12.5 kHz spacing) FM with 0.5 watt power output, and 16 channels for Digital Personal Mobile Radio 446 MHz (Digital PMR 446). Frequencies for Digital PMR 446 are from 446.103125 ...
On 1 April 2010, [10] the Malaysian Communications and Multimedia Commission (MCMC) introduced PMR446 (446.00625 MHz to 446.093750 MHz and 446.103125 MHz to 446.196875 MHz) in addition to 26.965 MHz to 27.405 MHz as a class assignment. [11] Subsequently, the MCMC revoked 477 MHz personal radio service as a class assignment on 1 January 2022. [12]
These awkward frequencies would prevent illegal US sets from being modified outside of the type approval system, though it was possible to have existing A.M. radios modified to comply with the new F.M. standard. [10] The choice of frequency would also give the UK electronics industry a head start in the production of unique UK only radios.
