Sec.  80.955   Radiotelephone installation.

   (a) Each U.S. flag vessel of less than 38 meters (124 feet) in length while
   subject to the Great Lakes Agreement must have a radiotelephone meeting the
   provisions of this subpart in addition to the other rules in this part
   governing ship stations using telephony.

   (b) Each U.S. flag vessel of 38 meters (124 feet) or more in length while
   subject to the Great Lakes Agreement must have a minimum of two VHF
   radiotelephone installations in operating condition meeting the provisions
   of this subpart. The second VHF installation must be electrically separate
   from the first VHF installation. However, both may be connected to the main
   power supply provided one installation can be operated from a separate power
   supply located as high as practicable on the vessel.

   (c) This paragraph does not require or prohibit the use of other frequencies
   for use by the same “radiotelephone installation” for communication
   authorized by this part.
