WWV 25 MHz back on the air
WWV’s 25 MHz Signal Back on the Air
TAGS: air, daily basis, dean lewis, Fort Collins, listeners, meter propagation, MHz signal, NIST, old times, Propagation Beacons, standards, technology, youtube 04/07/2014 WWV silenced its 25 MHz signal in 1977, but it’s back on the air “for old times’ sake” — officially on an “experimental basis.” Resurrecting the long-dormant standard time outlet operated by the National Institutes of Standards and Technology (NIST) was Matt Deutch, N0RGT, the Lead Electrical Engineer at WWV. It all came about after Dean Lewis, W9WGV, lamented the loss of the 25 MHz signal in an e-mail to Deutch, who surprised him by subsequently putting the signal back on the air on April 4 for about 3-1/2 hours. A listener in Scotland posted his reception of the WWV 25 MHz signal on YouTube. WWV is running another 25 MHz test today (April 7), which began at about 1530 UTC. “Matt promises the signal to be available for 24 hours,” said Lewis. “Members and listeners might be interested in hearing this historic event.” Lewis said he’d told Deutch that since 10 meter propagation has been so good at this point in Cycle 24, and he uses the various WWV frequencies as propagation beacons on a daily basis. “He responded that ‘for old times’ sake,’ they’d put the [25 MHz] signal back on the air for a while. I assumed, of course, that he was kidding, and so I didn’t check. Matt wasn’t kidding!” NIST said the 25 MHz broadcast consists of the normal WWV signal heard on all other WWV frequencies, at the same level of accuracy. The transmitter in Fort Collins, Colorado, puts out 2500 W into a “broadband monopole.” WWV has invited listeners’ comments and signal reports. |

Of course they need a budget for monitoring, maintenance, replacement, electricity bill, ... Apparently after turning it off for 37 years and probably doing no or little maintenance, it still works. So maybe the required budget was a little over-estimated. But you don't know those things in advance. Of course the electricity bill alone will be in the 5-digit range, but that should be peanuts for a government agency. |
