(b) The radiotelegraph station shall be so located that no harmful interference from extraneous mechanical or other noise will be caused to the proper reception of radio signals, and shall be placed in the upper part of the ship in a position of the greatest possible safety and as high as practicable above the deepest load waterline. The location of the radiotelegraph operating room or rooms shall be approved by the Commandant of the Coast Guard. The radiotelegraph installation shall be installed in such a position that it will be protected against the harmful effects of water or extremes of temperature, and shall be readily accessible both for immediate use in case of distress and for repair.

The sleeping accommodation of at least one radio officer shall be situated as near as practicable to the radiotelegraph operating room. In ships the keels of which are laid on or after May 26, 1965, this sleeping accommodation shall not be within the radiotelegraph operating room.
