Some hams take that concept to the extreme by U.S. $5.95 ���������������������������������� Printed in the United States launching satellites. Others like Bill Brown dabble with transmissions from Storm Chasing Near Space by means of Amateur Radio High Altitude Balloons (ARHAB). The “payload” may be a simple transmitter or it may be combined with with other experiments. Tracking the balloon to retrieve the payload requires Amateur Radio skill in direction-finding and using FAA winds aloft data to predict the landing zone.

    WWVB: a Half Century of Delivering Accurate Frequency and Time by Radio

    Volume 119 (2014) http://dx.doi.org/10.6028/jres.119.004 Journal of Research of the National Institute of Standards and Technology WWVB: A Half Century of Delivering Accurate Frequency and Time by Radio Michael A. Lombardi and Glenn K. Nelson National Institute of Standards and Technology, Boulder, CO 80305 [email protected] [email protected] In commemoration of its 50th anniversary of broadcasting from Fort Collins, Colorado, this paper provides a history of the National Institute of Standards and Technology (NIST) radio station WWVB. The narrative describes the evolution of the station, from its origins as a source of standard frequency, to its current role as the source of time-of-day synchronization for many millions of radio controlled clocks. Key words: broadcasting; frequency; radio; standards; time. Accepted: February 26, 2014 Published: March 12, 2014 http://dx.doi.org/10.6028/jres.119.004 1. Introduction NIST radio station WWVB, which today serves as the synchronization source for tens of millions of radio controlled clocks, began operation from its present location near Fort Collins, Colorado at 0 hours, 0 minutes Universal Time on July 5, 1963. Thus, the year 2013 marked the station’s 50th anniversary, a half century of delivering frequency and time signals referenced to the national standard to the United States public. One of the best known and most widely used measurement services provided by the U. S. government, WWVB has spanned and survived numerous technological eras. Based on technology that was already mature and well established when the station began broadcasting in 1963, WWVB later benefitted from the miniaturization of electronics and the advent of the microprocessor, which made low cost radio controlled clocks possible that would work indoors.

Lawrence Specialist in Asian Affairs August 1, 2013 Congressional Research Service 7-5700 www.crs.gov R41108 CRS Report for Congress Prepared for Members and Committees of Congress U.S.-China Relations: An Overview of Policy Issues Summary The United States relationship with China touches on an exceptionally broad range of issues, from security, trade, and broader economic issues, to the environment and human rights. Congress faces important questions about what sort of relationship the United States should have with China and how the United States should respond to China’s “rise.” After more than 30 years of fast-paced economic growth, China’s economy is now the second-largest in the world after that of the United States. With economic success, China has developed significant global strategic clout. It is also engaged in an ambitious military modernization drive, including development of extended-range power projection capabilities. At home, it continues to suppress all perceived challenges to the Communist Party’s monopoly on power. In previous eras, the rise of new powers has often produced conflict. China’s new leader Xi Jinping has pressed hard for a U.S. commitment to a “new model of major country relationship” with the United States that seeks to avoid such an outcome. The Obama Administration has repeatedly assured Beijing that the United States “welcomes a strong, prosperous and successful China that plays a greater role in world affairs,” and that the United States does not seek to prevent China’s re-emergence as a great power.

    Five Years of VLF Worldwide Comparison of Atomic Frequency Standards

    RADIO SCIENCE, Vol. 2 (New Series), No. 6, June 1967 Five Years of VLF Worldwide Comparison of Atomic Frequency Standards B. E. Blair,' E. 1. Crow,2 and A. H. Morgan (Received January 19, 1967) The VLF radio broadcasts of GBR(16.0 kHz), NBA(18.0 or 24.0 kHz), and NSS(21.4 kHz) have enabled worldwide comparisons of atomic frequency standards to parts in 1O'O when received over varied paths and at distances up to 9000 or more kilometers. This paper summarizes a statistical analysis of such comparison data from laboratories in England, France, Switzerland, Sweden, Russia, Japan, Canada, and the United States during the 5-year period 1961-1965. The basic data are dif- ferences in 24-hr average frequencies between the local atomic standard and the received VLF radio signal expressed as parts in 10"'. The analysis of the more recent data finds the receiving laboratory standard deviations, &, and the transmission standard deviation, ?, to be a few parts in 10". Averag- ing frequencies over an increasing number of days has the effect of reducing iUi and ? to some extent. The variation of the & with propagation distance is studied. The VLF-LF long-term mean differences between standards are compared with the recent portable clock tests, and they agree to parts in IO". 1.
