How the National Bureau of Standards helped make radio
The word “radio,”didn’t become part of our vocabulary until 1911, and it happened thanks in part to J. Howard Dellinger, a radio scientist at the National Bureau of Standards (NBS), the agency that became the National Institute of Standards and Technology (NIST).
How the National Bureau of Standards helped make “radio” This was originally published as “NIST’s Role in the Early Decades of Radio (1911-1933)” on the National Institute of Science and Technology’s blog, Taking Measure…….Dan —————————————– Even if you weren’t able to watch the recent Super Bowl on TV, you could still listen to the play-by-play commentary on the radio. But radio does more than just broadcasting sporting events or playing music. It plays a major role in emergency response, navigation and science. The word “radio,” however, didn’t become part of our regular vocabulary until 1911, and it happened thanks in part to J. Howard Dellinger, a radio scientist at the National Bureau of Standards (NBS), the agency that became the National Institute of Standards and Technology (NIST). This came about when the second International Radiotelegraph Conference was being planned in London, and a professor sent Dellinger a paper that he was going to present to the conference for review. At the time, “wireless” was used as the term for radio communication, especially by the British. However, NIST was charged with revising standards in preparation for the conference, and Dellinger suggested that the professor use “radio,” which was already becoming a popular word in the U.S., instead of “wireless.” The professor agreed, and the word “radio” went on to become the universally accepted term. Dellinger not only played a role in popularizing the word “radio,” but he also played a role in the first radio work done at NIST. A commercial company asked NIST to calibrate a wavemeter, a device developed by one of its engineers that measures electromagnetic waves like those of radio. Dellinger was known as the wireless expert and took on the project of calibrating the first radio instrument at NIST. A New Type of Radio Receiver But for radio to become mainstream, it first had to be commercialized, which began with its introduction into households. However, the challenge was building a radio set that used the electrical current, called alternating current (AC), which powered lights, fans and kitchen appliances when plugged into wall sockets. The predecessor to this technology was developed and patented by two researchers, Percival D. Lowell and Francis W. Dunmore, at NBS in 1922. They called their invention the “mousetrap.” [[Insert how-the-nbs-helped-make-radio-photo.jpg here]] The “mousetrap” was a receiver for a radio amplifier that could run on AC. This was considered a breakthrough because at that time radios were only able to be powered by direct current (DC) provided by batteries. These batteries were bulky and heavy, had to be charged from time to time and were considered dangerous because of the acid used in them. The researchers’ prototype meant the radio could be used in homes without causing damage and with the same performance quality. Lowell and Dunmore filed two more patents together for other innovations, and for the “mousetrap” they sold the rights to the Dubilier Condenser Corporation. Little did they know that, because there was no uniform policy on patents issued to government employees, their actions would result in more than a decade of litigation over who legally had the rights to the patent. While they were tied up in court, the Radio Corporation of America (RCA) developed its own model of the AC radio in 1926. Its model later became the first AC-powered radio sold to consumers. Flying by Radio During the early years of flight navigation, NIST was doing research to assist pilots while they were flying and landing. Pilots needed three things to get their bearings when flying “blind,” meaning it’s foggy, too dark or too cloudy to see. They needed to know the longitudinal position, altitude and speed of the aircraft, which were all achieved by various beacons installed in the plane. The remaining issue was that there were two frequencies the pilot constantly had to switch between the frequency that the Department of Commerce used to send weather information to planes and ships, which sometimes caused interference for pilots, and the frequency the radio beacon operated on, which gave altitude and other information. Dunmore created a prototype, but Harry Diamond, a radio engineer who joined NIST in 1927, completed the device, called the radio guidance system. Diamond solved the problem by developing a separate device that allowed for voice communication to the pilot without receiving any outside interference from ships’ radios. A Curtiss Fledgling, a trainer aircraft developed for the U.S. Navy, was equipped with the device, and flight tests were performed between NIST’s experimental air station at College Park, Maryland, and Newark Airport in New Jersey in foggy weather. After a series of successful tests were performed, the device was turned over to be used by the Department of Commerce in 1933. Praise From a Famous Inventor While mostly intended for serious users, some of NIST’s journals and publications were popular with the public. One such book, titled The Principles Underlying Radio Communication, covered topics such as elementary electricity, radio circuits and electromagnetic waves and was also published as a textbook for soldiers in the U.S. Army. The famous inventor Thomas Edison received a copy from NIST and wrote a letter thanking the first director, Samuel W. Stratton, for publishing it, saying it was “the greatest book on this subject that I have ever read.” As these and other examples show, NIST had a significant influence on radio research between 1911 and 1933. However, NIST’s radio work didn’t end with the first blind landing. NIST would continue to contribute to the field leading up to and during World War II, and research continues to this day in areas such as 5G, public safety communications and spectrum sharing. —————————— ABOUT THE AUTHOR Alex Boss is a general assignment writer in the NIST Public Affairs Office and covers standard reference materials (SRM).

Ron, KG6HSQ, announced that Hal Potter, KF6FHL, is currently in a local care facility and invited members to stop by and see him. Ron is also working on a new FARC internet home page and the new address will be wp.fallbrookarc.org. He is currently working on the new page and expects it to be operational in the near future. He said that the 2-meter repeater was currently working fine but is anticipating that the old interference may possibly reappear as warmer weather approaches. The interference seems to be much worse as temperatures rise.
Brent, KJ6UMY, introduced two of his friends, John Landry and Mike Kenny. John and Mike are both U.S. Navy veterans and both are docents on the USS Midway Aircraft Carrier located in San Diego and both will be presenting the program today, “The Battle of Midway”.
John said that the Midway was one of the top museums in the US. Last year 1.4 million people visited the Midway. On a single day last year there were 7,500 people that visited the Midway. The Midway is a non-profit organization and has been financially very successful compared to lots of other museums. The Midway offers a variety of community programs. There is a Youth program where youngsters can come aboard and spend the night, there are dinner programs of various kinds on the deck, there are docent guided tours and many other interesting programs available to the public when they visit or for special programs. John said that the Midway organization was very fortunate in that maintenance, especially the sea aspect, of the vessel had been well thought out prior bringing the Midway to San Diego. The underwater part of the ship has been coated with an Epoxy coating which has minimized the underwater maintenance aspect. Opening of new sections of the ship is an ongoing project and is continuous. John suggested a very good book for reading. The book, “Shattered Sword”, by Jonathan Parshall. It is “The Untold Story of the Battle of Midway”.
Mike had served on destroyers while in the Navy. He said that the Battle of Midway (The island of Midway) was probably the most significant and important sea battle in history. It was a time when the evolution was taking place where Aircraft Carriers were becoming the predominant sea vessel rather than the historic Battleship. Japan had recognized this important factor before any other nation and its Navy had become the most powerful in the world. Prior to the beginning of the war the US was ranked number 14th in the world, even behind Switzerland. Japan had 2.6 million people in the uniformed services and the US had 500,000.
Preparing for the Pacific war, Japan developed “Operation K”. One of its primary functions was to locate the US carriers and the US Pacific Fleet. This operation actually continued on into 1942 when two Japanese bombers were sent to drop bombs again on Pearl Harbor from high altitude and at night. They arrived during a heavy thunderstorm at Pearl Harbor. One dropped bombs in the ocean and the other bombs were dropped harmlessly in the mountains did no damage. There were other “Operation K’s”. One was scouting Johnson and Midway Islands.
Mike showed a video that explained the logistics of the battle of Midway from both the US and Japanese perspective. It showed ship movements, both US and Japanese. Aircraft flights and attacks and some actual footage of the attack on the island. A very interesting and well done program.
Someone asked when the USS Midway was constructed. John said it was constructed on a battleship “frame” which was common at that time. It’s center of gravity was too high so the Midway “overheads” were all lowered to compensate for this. The ship was constructed between 1943 and 1945 and was commissioned 2 weeks after the war ended.
With no further business the meeting was adjourned at 1620.
