§ 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.
