Frequency Band

Land Mobile Radios (LMRs) operate in the following frequency bands: VHF, UHF1, UHF2, 700 MHz, 800 MHz, 900 MHz. These bands permit two-way radio communications by civil, government, and military users. The frequency bands supported by a particular radio's codeplug are identified in the Primary Frequency Band and Secondary Frequency Band (for dual-band radios) fields. The frequency spectrum is divided according to International Telecommunication Union (ITU) regulations.
