WWV Shortwave Time Broadcasts May Be Slashed In 2019 (qrz.com) 305

New submitter SteveSgt writes: A forum thread on QRZ.com indicates that the shortwave time broadcasts by the National Institute of Standards and Technology (NIST) from stations WWV (Colorado) and WWVH (Hawaii) may be slashed in budget year 2019. [One of the proposed reductions includes "$6.3 million supporting fundamental measurement dissemination, including the shutdown of NIST radio stations in Colorado and Hawaii."] While the WWV broadcasts may seem like an anachronism to some Slashdotters, they remain a crucial component in many unexpected services, from over-the-air broadcasters and traffic signals, to medical devices, wall clocks, and wrist watches. The signals serve as standard beacons for radio propagation, and as a frequency reference for alignment of a broad range of communications equipment. It's easy to imagine that not even the NIST knows every service and device that could be impacted by this decision.

    As far as time and frequency dissemination goes, GPS does a vastly better job, with better coverage in almost all cases.

        They used to be, back when clocks were powered from an AC wall socket. Their gears were synchronized with the AC motor, and the power company worked really really hard to make sure the long-term average AC cycle was exactly 60 Hz. If equipment problems caused the frequency to drop slightly below 60 Hz, they'd run at slightly above 60 Hz for long enough to get the clocks back on the correct time.

        Then we switched to clocks running off batteries with built-in quartz timing mechanisms. In theory they're better, but in practice they're never calibrated well enough or their calibration drifts with age and temperature, making them less accurate than the old AC powered clocks. The best quartz watch I had lost a little less than a second a month. Then I got too greedy and killed the golden goose - tried adjusting the quartz timing mechanism myself. After that I could never get it below 2 seconds of drift per month. What I didn't realize until it was too late was that as the error gets smaller, you have to wait longer between each adjustment (weeks) to determine if you had improved it or overshot. With the 60 Hz power line method, only a single clock has to be calibrated to be super-accurate; and all the other clocks powered by AC synchronize off it.

          Just about all plug-in clocks that do not have a wall-wart, like the cheap LED bedside alarm clocks or the clock on your stove, still are timed from the utility. The chips that do this are wickedly inexpensive and *just work*.

          My grandfather worked in rural electrification back in the day. He told me that they tracked variations in frequency during the day and intentionally caught up on any errors at night when load was (relatively) low, just to keep the clocks accurate.

          Define your accuracy requirements. Quartz clocks have orders of magnitude better short term accuracy than anything grid synchronized. The grid has far greater accuracy over the long term.

          The GP said millisecond accuracy, the fact is that wall synchronized clocks never achieved this. On a given day they could be all over the place. In fact their accuracy can often be out by many seconds before producers take action to get the frequency back in sync with the clock, and that is hardly surprising when you think

        The loss of those frequencies will obsolete the older HF clocks, like the Heathkit GC-1000 "Most Accurate Clock" I have in my ham shack. As well as removing the other functions they provided besides time, such as precision frequency reference (zero beat a signal generator or receiver VFO against WWV's carrier, and you know it is exactly on frequency), and the various frequencies throughout the HF band provide useful propagation checks, as well.

          It's just a few transmitters and some awesome clocks, very carefully intertwined.

        You can of course connect a single GPS receiver to your NTP server and thereby keep your whole network within a millisecond or so of perfect time using just one GPS server.

      This may surprise you, but GPS in-building penetration is zero. Whereas the longwave signals from WWV keep a clock I have in my basement synchronized. So yeah, GPS does a vastly better job at providing location, because that's what it's for, and pretty much is shit for providing cheap time sync.
      Oh, and as of the 2012 budget, GPS operating costs were $2M ... *a day*.

      The real issue here is that this is something that primarily provides a useful service for the little guy and doesn't have armies of lobbyists shilling it, so even if it cost $1.50/yr, let's cut it, because it's SOCIALISM.

        It's not that simple.

        First it needs an accurate source of time. These days that could be GPS, but it needs to keep working when GPS is not available so you need an atomic clock at each site.

        Then you need some equipment to generate the signal. Yeah, a Raspberry Pi could do it, but have you certified that Python script to be correct and to produce a signal that is synchronized within nanoseconds of the atomic clock?

        Finally you need a high power transmitter to broadcast it. Actually you need five because it broadcasts on five different frequencies.

        Oh, and you need to keep monitoring it, not just at the transmitter but around the country to ensure propagation and accuracy. Conditions change, if you are relying on it for anything important you have to keep checking.

        $6.3m actually sounds quite reasonable for such a system.
