Text Appearing Before Image:
radio telegraphic service. WIRELESS ON WORLDS LARGEST SHIP Not the least important feature of the Hamburg-American ship Imperator, which recently completed her maiden trip across the Atlantic, is the wireless telegraph equipment on both the main vessel and the motor operated lifeboats. The motor boat equipments have a working range of 200 miles, while the range of the main vessel equipment is 1,500 miles. The ship has two reserve antennas and two receiving instruments for long and short waves, designed for news sen-ice and rescue work. The station is directed by three operators, one of whom is always at the key. The Imperator will be within direct communication with land all the way across the Atlantic. Dired wireless communication between America and Asia is innv an accomplished fact, the United States Army Signal Corps Station at Nome, Alaska, having been in nightly communication with the Russian station at Anadyr, Siberia. 500 miles west of Nome. 712 POPULAR ELECTRICITY and the WORLDS ADVANCE
Text Appearing After Image:
Arlington Station Towers Time Receiving Room FLASHING TIME OVERTHE OCEAN At noon every day the time signal known to mariners as the tick is flashed from the Naval Observatory in Washington. Five minutes before 12 o'clock Washington meridian time, the huge standard time clock, which controls the United States Observatory time throughout the Atlantic and Middle Western States, is connected with the Arlington Wireless station. Every tick of the clock instantaneously closes the key of the sending apparatus and the Hertzian waves are released to be picked up by stations within the three thousand mile sending radius of this powerful station. Through the Naval Hydrographic Office, all warships and merchantmen of the various nations have been notified of the time signal and most of them prepare for it some few minutes previous to the time of the first signal.
