POLICING THE ETHER 295 a special high-frequency radiotelephone for a new fleet of patrol boats put in service by the Coast Guard than the Bureau was asked to convert their radio compasses to similar high frequency reception. The new radio compass, using a frequency of 2100 kc led next to a portable unit that the Bureau of Navigation sought for shipping, with a useful range of 90 to 7700 kc.218 — While the radio compass was useful for locating a radio signal source, acting as a radio beacon to guide ships at sea or planes in flight, Federal aviation, when it added passengers to its mail flights and extended its opera- tions, required greater safeguards than the compass could provide.219 (Euro- pean aviation was to rely entirely on radio direction finders for another two decades at least.) Shortly after the establishment of the Aeronautical Division in Commerce, the Bureau was asked to begin work at once on better air navigation aids. -The Bureau's first crude radio guidance system for aircraft was tested in 1921, when a pilot flew along a course designated by signals sent from two transmitting coils on the ground. The prototype radio beacon produced 2 years later for the Army Air Service was put aside for further work on the radio compass. Without passengers, flying the mail was high adventure and the pilots liked it that way. Work on a beacon was not resumed until 1926.220 It was the inventive talents of Harry Diamond, who came to the Bureau in 1927, that resulted 2 years later in the first visual-type radiobeacon system anywhere, enabling a pilot to keep on course and know his approxi- mate position at all times while in flight.221 Incidental to the system, the Bureau constructed receiving sets of special design for use in planes and improved shielding against interference from the engine ignition. A year later, in 1930, a 15-pound unit that Diamond added to the radio range beacon 218 S428 (Koister and Dunmore, 1921); NBS Annual Report 1922, p. 57; S525 (Dunmore, 1926); S536 (Dunmore, 1926). 219 By 1924 regular day and night mail service had been established between New York and San Francisco via Chicago and Cheyenne. By the end of 1928, 48 airways covering 20,000 miles linked 355 cities in the United States. Slosson, The Great Crusade and After, p. 401; Aircraft Year Book, 1929 (New York: Aeronautics Chamber of Commerce of America, Inc.), p. 103. "°NBS Annual Report 1921, p. 68; S480 (Engle and Dunmore, 1923). Letter, Harry Diamond to Leland Jamieson, Nov. 16, 1939 (NBS Box 431, IEW), credits P. D. Lowell of the Bureau with the suggestion for the radio range beacon about 1922, the experimental work carried out under his guidance in 1922—23 by Engel and Dunmore. 221 RP1S9 (Dellinger, Diamond, and Dunmore, 1929). Born in Russia at the turn of the century, Diamond graduated from MIT and taught for 4 years at Lehigh University before he came to the Bureau as a radio engineer. His electronic genius served the Bureau and the Nation well, notably during World War II. His driving, tireless energy was to bring him to an untimely death in 1948.
296 A Curtiss Fledgling was equipped in 1931 with the first complete system for blind landing of an aircraft and demonstrated its practicability by an extensive series of hooded landings at College Park, Md., and at Newark Airport. The dual-pointer landing indicator on the instrument panel gave the pilot a visual indication of his position in space with respect to the approach glide path. Adopted and adapted by the Civil Aeronautics Administration, this NBS radio instrument landing system is basic to the present universally used ILS blind landing system.
