OTHER WAVE LENGTHS.
Second. In addition to the normal sending wave length lengths! all stations, except as provided hereinafter in these regulations, may use other sending wave lengths: Provided, That they do not exceed six hundred meters or that they do exceed one thousand six hundred meters: Provided further, That the character of the waves emitted conforms to the requirements of regulations third and fourth following

Third. At all stations if the sending apparatus, to Use of “pure be referred to hereinafter as the “transmitter," is of such' a character that the energy is radiated in two or more wave lengths, more or less sharply defined, as indicated by a sensitive wave meter, the energy in no one of the lesser waves shall exceed ten per centum of that in the greatest.
USE OF A “SHARP WAVE. Fourth. At all stations the logarithmic decrement per shampofrave." complete oscillation in the wave trains emitted by the transmitter shall not exceed two-tenths, except when sending distress signals or signals and messages relating thereto.
Fifth. Every station on shipboard shall be prepared to Distress send distress calls on the normal wave length designated by the international convention in force, except on vessels of small tonnage unable to have plants insuring that wave length.
SIGNAL OF DISTRESS.
Sixth. The distress call used shall be the international Distress sig. signal of distress
Seventh. When sending distress signals, the trans- Wave for
distress sig. mitter of a station on shipboard may be tuned in such a nals. manner as to create a maximum of interference with a maximum of radiation.
DISTANCE REQUIREMENT FOR DISTRESS SIGNALS.
Eighth. Every station on shipboard, wherever practi- Distance re cable, shall be prepared to send distress signals of the distress sigcharacter specified in regulations fifth and sixth with sufficient power to enable them to be received by day

Ninth. All stations are required to give absolute tress messages. priority to signals and radiograms relating to ships in
distress; to cease all sending on hearing a distress signal; and, except when engaged in answering or aiding the ship in distress, to refrain from sending until all signals and radiograms relating thereto are completed.
REDUCED POWER FOR SHIPS NEAR A GOVERNMENT STATION.
Reduced power for ships near a Government station.
Tenth. No station on shipboard, when within fifteen nautical miles of a naval or military station, shall use a transformer input exceeding one kilowatt, nor, when within five nautical miles of such a station, a transformer input exceeding one-half kilowatt, except for sending signals of distress, or signals or radiograms relating thereto.
Communica- Eleventh. Each shore station open to general public tion required between shore service between the coast and vessels at sea shall be bound and shipboard to exchange radiograms with any similar shore station
and with any ship station without distinction of the radio systems adopted by such stations, respectively, and each station on shipboard shall be bound to exchange radiograms with any other station on shipboard without distinction of the radio systems adopted by each station, respectively.
It shall be the duty of each such shore station, during required.
the hours it is in operation, to listen in at intervals of not less than fifteen minutes and for a period not less than two minutes, with the receiver tuned to receive messages of three hundred meter wave lengths.
DIVISION OF TIME.
Government and commercial stations.
Twelfth. At important seaports and at all other places time between where naval or military and private or commercial shore
stations operate in such close proximity that interference with the work of naval and military stations can not be avoided by the enforcement of the regulations contained in the foregoing regulations concerning wave lengths and character of signals emitted, such private or commercial shore stations as do interfere with the reception of signals by the naval and military stations concerned shall not
use their transmitters during the first fifteen minutes of Exceptions, each hour, local standard time. The Secretary of Commerce and Labor may, on the recommendation of the department concerned, designate the station or stations which may be required
to observe this division of time.
GOVERNMENT STATIONS TO OBSERVE DIVISIONS OF TIME.
Thirteenth. The naval or military stations for which Time for the above-mentioned division of time may be established shall transmit signals or radiograms only during the first fifteen minutes of each hour, local standard time, except in case of signals or radiograms relating to vessels in distress, as hereinbefore provided.
USE OF UNNECESSARY POWER.
Fourteenth. In all circumstances, except in case of sig. Minimum nals or radiograms relating to vessels in distress, all power to be stations shall use the minimum amount of energy necessary to carry out any communication desired.
GENERAL RESTRICTIONS ON PRIVATE STATIONS.
Fifteenth. No private or commercial station not engaged in the transaction of bona fide commercial business by radio communication or in experimentation in connection with the development and manufacture of radio apparatus for commercial purposes shall use a transmitting wave length exceeding two hundred meters, or a transformer input exceeding one kilowatt, except by special authority of the Secretary of Commerce and Labor contained in the license of the station: Provided, That the owner or operator of a station of the character mentioned from penalties. in this regulation shall not be liable for a violation of the requirements of the third or fourth regulations to the penalties of one hundred dollars or twenty-five dollars, respectively, provided in this section unless the person maintaining or operating such station shall have been notified in writing that the said transmitter has been found, upon tests conducted by the Government, to be so adjusted as to violate the said third and fourth regulations, and opportunity has been given to said owner or operator to adjust said transmitter in conformity with said regulations.
SPECIAL RESTRICTIONS IN THE VICINITIES OF GOVERNMENT
Sixteenth. No station of the character mentioned in
if near Goyregulation fifteenth situated within five nautical miles of ernment staa naval or military station shall use a transmitting wave length exceeding two hundred meters or a transformer input exceeding one-half kilowatt.
SHIP STATIONS TO COMMUNICATE WITH NEAREST SHORE
Communications from shipboard.
Seventeenth. In general, the shipboard stations shall transmit their radiograms to the nearest shore station. A sender on board a vessel shall, however, have the right to designate the shore station through which he desires to have his radiograms transmitted. If this can not be done, the wishes of the sender are to be complied with only if the transmission can be effected without interfering with the service of other stations.
