PMR Telsiz frekansları ;

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.
