Title 47 › Chapter 5— WIRE OR RADIO COMMUNICATION › Subchapter III— SPECIAL PROVISIONS RELATING TO RADIO › Part II— Radio Equipment and Radio Operators On Board Ship › § 354a
Cargo ships of 300 gross tons up to less than 1,600 gross tons may use a radiotelephone instead of a radiotelegraph if the radio meets these rules. The radio must be placed high on the ship where noise won’t block messages. If it is not on the bridge, there must be good communication with the bridge. It must work on the frequencies and signal types the Commission sets for distress and safety, and must clearly send and receive signals ship-to-ship for at least 150 nautical miles by day under normal conditions. The ship must always have a main power source that can run the radio for that range. If batteries are used, they must run the transmitter and receiver for at least six continuous hours in normal use. Radios installed on or after November 19, 1952 must also have a reserve power source located in the upper part of the ship unless the main source is already there.
