What will you do if WWVB goes silent?
In an article on the popular website Hackaday, Tom Nardi writes:
Buried on page 25 of the 2019 budget proposal for the National Institute of
Standards and Technology (NIST), under the heading “Fundamental
Measurement, Quantum Science, and Measurement Disseminationâ€, there’s a
short entry that has caused plenty of debate and even a fair deal of anger
among those in the amateur radio scene:
*NIST will discontinue the dissemination of the U.S. time and frequency via
the NIST radio stations in Hawaii and Ft. Collins, CO. These radio stations
transmit signals that are used to synchronize consumer electronic products
like wall clocks, clock radios, and wristwatches, and may be used in other
applications like appliances, cameras, and irrigation controllers.*
The NIST stations in Hawaii and Colorado are the home of WWV, WWVH, and WWVB
<https://www.nist.gov/pml/time-and-frequency-division/time-services>. The
oldest of these stations, WWV, has been broadcasting in some form or
another since 1920; making it the longest continually operating radio
station in the United States. Yet in order to save approximately $6.3
million, these time and frequency standard stations are potentially on the
chopping block.
What does that mean for those who don’t live and breathe radio? The loss of
WWV and WWVH is probably a non-event for anyone outside of the amateur
radio world. In fact, most people probably don’t know they even exist.
Today they’re primarily used as frequency standards for calibration
purposes, but in recent years have been largely supplanted by low-cost
oscillators.
