  § 80.1127   On-scene communications.

   (a) On-scene communications are those between mobile unit in distress and
   assisting mobile units, and between the mobile units and unit coordinating
   search and rescue operations.

   (b) Control of on-scene communications is the responsibility of the unit
   coordinating search and rescue operations. Simplex communications must be
   used so that all on-scene mobile stations may share relevant information
   concerning the distress incident. If direct-printing telegraphy is used, it
   must  be in the forward error-correcting mode in accordance with ITU-R
   Recommendation M.625-3, with Annex, as specified in § 80.1101.

   (c) The preferred frequencies in radiotelephony for on-scene communications
   are 156.8 MHz and 2182 kHz. The frequency 2174.5 kHz may also be used for
   ship-to-ship on-scene communications using narrow-band direct-printing
   telegraphy in the forward error correcting mode in accordance with ITU-R
   M.625-3 (incorporated by reference, see § 80.7), as specified in § 80.1101.

   (d) In addition to 156.8 MHz and 2182 kHz, the frequencies 3023 kHz, 4125
   kHz, 5680 kHz, 123.1 MHz and 156.3 MHz may be used for ship-to-aircraft
   on-scene communications.

   (e)  The  selection  or  designation  of  on-scene  frequencies is the
   responsibility  of the unit coordinating search and rescue operations.
   Normally, once an on-scene frequency is established, a continuous aural or
   teleprinter watch is maintained by all participating on-scene mobile units
   on the selected frequency.
