A Century of WWV
Volume 124, Article No. 124025 (2019) https://doi.org/10.6028/jres.124.025 Journal of Research of the National Institute of Standards and Technology A Century of WWV Glenn K. Nelson National Institute of Standards and Technology, Radio Station WWV, Fort Collins, CO 80524, USA [email protected] WWV was established as a radio station on October 1, 1919, with the issuance of the call letters by the U.S. Department of Commerce. This paper will observe the upcoming 100th anniversary of that event by exploring the events leading to the founding of WWV, the various early experiments and broadcasts, its official debut as a service of the National Bureau of Standards, and its role in frequency and time dissemination over the past century. Key words: broadcasting; frequency; radio; standards; time. Accepted: September 6, 2019 Published: September 24, 2019 https://doi.org/10.6028/jres.124.025 1. Introduction WWV is the high-frequency radio broadcast service that disseminates time and frequency information from the National Institute of Standards and Technology (NIST), part of the U.S. Department of Commerce. WWV has been performing this service since the early 1920s, and, in 2019, it is celebrating the 100th anniversary of the issuance of its call sign. 2. Radio Pioneers Other radio transmissions predate WWV by decades. Guglielmo Marconi and others were conducting radio research in the late 1890s, and in 1901, Marconi claimed to have received a message sent across the Atlantic Ocean, the letter “S” in telegraphic code [1]. Radio was called “wireless telegraphy” in those days and was, if not commonplace, viewed as an emerging technology. -

The use of additional transmitters that simultaneously broadcast the programs of a primary origi- nating station is an effective and economical method that MM Docket No. 87-6 could be applied in some circumstances to improve and extend a station's service area.

Similar Broadcast Stations experiments have been conducted in Boston (WBZ). Charlotte. North Carolina (WBT). Cincinnati. Ohio (WSAI). and in Washington. D.C. (WINX and WWDC). NOTICE OF INQUIRY Synchronized groups of transmitters have been used in the AM band on a large scale in Europe for many years. Adopted January 15, 1987; ReIeased March 3, 1987 and more recently in Japan. These foreign operations have been based upon the same theoretical bases as the By the Commission: earlier Uniied States operations.4 The results of the inter- national experience have been largely consiStent with those obtained in the United States.
