§ 95.631   Emission types.

   (a) A GMRS transmitter must transmit only emission types A1D, F1D, G1D,
   H1D, J1D, R1D, A3E, F3E, G3E, H3E, J3E or R3E. A non-voice emission is
   limited to selective calling or tone-operated squelch tones to
   establish or continue voice communications. See § 95.181 (g) and (h).

   (b) An R/C transmitter may transmit any appropriate non-voice emission
   which meets the emission limitations of § 95.633.

   (c) A CB transmitter may transmit only emission types A1D, H1D, J1D,
   R1D, A3E, H3E, J3E, R3E. A non-voice emission is limited to selective
   calling or tone-operated squelch tones to establish or continue voice
   communications. See § 95.412 (b) and (c).

   (d) An FRS unit may transmit only emission type F3E or F2D. A non-voice
   emission is limited to selective calling or tone-operated squelch tones
   to establish or continue voice communications, digital data
   transmission of location information or text messaging.

   (e) No GMRS or CB transmitter shall employ a digital modulation or
   emission.

   (f) No GMRS, CB or R/C transmitter shall transmit non-voice data.

   (g) An LPRS station may transmit any emission type appropriate for
   communications in this service. Two-way voice communications, however,
   are prohibited.

   (h) A MedRadio station may transmit any emission type appropriate for
   communications in this service. Voice communications, however, are
   prohibited.

   (i) A WMTS station may transmit any emission type appropriate for
   communications in this service, except for video and voice. Waveforms
   such as electrocardiograms (ECGs) are not considered video.

   (j) 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.

   (k) DSRCS-OBUs are governed under subpart L of this part.
