A MURS transmitter must transmit only emission types A1D, A2B, A2D, A3E, F2B, F1D, F2D, F3E, G3E. Emission types A3E, F3E and G3E include
selective calling or tone-operated squelch tones to establish or continue voice communications. MURS transmitters are prohibited from transmitting
in the continuous carrier mode. The authorized bandwidth for any emission type transmitted by a MURS transmitter is specified as follows:
- ALL A3E emissions are limited to 8 kHz.
- Emissions other than A3E on frequencies 151.820 MHz, 151.880 MHz, and 151.940 MHz are limited to 11.25 kHz.
- Emissions other than A3E on frequencies 154.570 and 154.600 MHz are limited to 20.0 kHz.
- MURS transmitters shall be designed to comply with the emission masks described in
47 CFR 95.635.
Each Multi-Use Radio Service transmitter (a transmitter that operates or is intended to operate in the MURS) must be certificated in
accordance with Part 95, Subpart J of the Commission’s rules. Those radio units certificated as of November 12, 2002 need not be
recertificated. No MURS unit, under any condition of modulation, shall exceed 2 Watts transmitter power output.
