PMR446
PMR446 (Personal Mobile Radio, 446 MHz) is a radio frequency part of the UHF range that is open without licensing for personal usage in most members of the European Union. It has roughly the same use as FRS in the United States. Depending on surrounding terrain range can vary from a few hundred meters (in a city) to a few kilometers (flat coutryside).
Technical information
There are eight FM channels separated by 12.5kHz from each other. Per regulation, maximum power, like FRS, is 500mW and equipment must be handheld with a fixed antenna. CTCSS is usually used, with more upmarket models also featuring DCS.
