Sec. 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.
