  Hot News - PMR446 FRS

Technical information[edit]
Analogue PMR446 covers band 446.0–446.1 MHz and digital dPMR/DMR cover 446.1–446.2 MHz; CEPT envisions that the digital band may be extended onto analogue band in the future.

Radios may now have removable antennas in some countries as long as the ERP does not exceed 500 mW, for example in the UK.[7] The general ECC decision[8] however still requires integral antennas and the actual implementation varies between different countries.

Analogue FM[edit]

Kenwood TK3301 and TK3501 PMR446 radios
Analogue PMR uses eight FM channels separated by 12.5 kHz from each other. Per regulation, maximum power, like FRS, is 500 mW ERP and equipment must be used on a mobile basis. CTCSS is usually used, with more upmarket models also featuring DCS and/or fixed-carrier voice inversion.

PMR Channel Frequency (MHz)
1 446.00625
2 446.01875
3 446.03125
4 446.04375
5 446.05625
6 446.06875
7 446.08125
8 446.09375
