§  80.1165   Assignment and use of frequencies.

   Frequencies for general radiotelephone purposes are available to ships
   in three radio frequency bands. Use of specific frequencies must meet
   the Commission's rules concerning the scope of service and the class of
   station with which communications are intended. The three frequency
   bands are:

   (a) 156-158 MHz (VHF/FM Radiotelephone). Certain frequencies within
   this band are public correspondence frequencies and they must be used
   as working channels when communicating with public coast stations.
   Other working frequencies within the band are categorized by type of
   communications for which use is authorized when communicating with a
   private coast station or between ships. Subpart H of this part lists
   the frequencies and types of communications for which they are
   available.

   (b) 1600-4000 kHz (SSB Radiotelephone). Specific frequencies within
   this band are authorized for single sideband (SSB) communications with
   public and private coast stations or between ships. The specific
   frequencies are listed in subpart H of this part.

   (c) 4000-23000 kHz (SSB Radiotelephone). Specific frequencies within
   this band are authorized for SSB communications with public and private
   coast stations. The specific frequencies are listed in subpart H of
   this part.
