Sec. 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 Sec. 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
Recommendation M.625–3, “Direct-printing Telegraph Equipment Employing
Automatic Identification in the Maritime Mobile Service,” with Annex, 1995,
as specified in Sec. 80.1101. ITU-R Recommendation M.625–3 with Annex is
incorporated by reference. The Director of the Federal Register approves
this incorporation by reference in accordance with 5 U.S.C. 552(a) and 1 CFR
Part 51. Copies of this standard can be inspected at the Federal
Communications Commission, 445 12th Street, SW., Washington, DC (Reference
Information Center) or at the National Archives and Records Administration
(NARA). For information on the availability of this material at NARA, call
202–741–6030, or go to:

ations.html. The ITU-R Recommendation can be purchased from the
International Telecommunication Union (ITU), Place des Nations, CH–1211
Geneva 20, Switzerland.
(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.
