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.
