Sec.  80.1129   Locating and homing signals.

   (a) Locating signals are radio transmissions intended to facilitate the
   finding of a mobile unit in distress or the location of survivors. These
   signals include those transmitted by searching units and those transmitted
   by the mobile unit in distress, by survival craft, by float-free EPIRBS, by
   satellite EPRIBs, and by search and rescue radar transponders to assist the
   searching units.

   (b) Homing singnals are those locating signals which are transmitted by
   mobile units in distress, or by survival craft, for the purpose of providing
   searching units with a signal that can be used to determine the bearing to
   the transmitting stations.

   (c) Locating signals may be transmitted in the following frequency bands:
   117.975–136 MHz, 121.5 MHz, 156–174 MHz, 406–406.1 MHz, and 9200–9500 MHz.

   (d) The 9 GHz locating signals must be in accordance with ITU-R
   Recommendation M.628–3, “Technical Characteristics for Search and Rescue
   Radar Transponders,” with Annexes, 1994, as specified in  Sec. 80.1101. ITU-R
   Recommendation M.628–3 with Annexes is incorporated by reference. The
   Director of the Federal Register approves this incorporation by reference in
