WWVB's Colorado location makes the signal weakest on the U.S. east coast, where urban density also produces considerable interference. In 2009, NIST raised the possibility of adding a second time code transmitter, on the east coast, to improve signal reception there and provide a certain amount of robustness to the overall system should weather or other causes render one transmitter site ...
WWV Transmitter Building (2002 or earlier) WWV's 15 MHz antenna WWV is a shortwave ("high frequency" or HF) radio station, located near Fort Collins, Colorado.It has broadcast a continuous time signal since 1945, and implements United States government frequency standards, with transmitters operating on 2.5, 5, 10, 15, 20, and 25 MHz.

The audio tones are suppressed while WWV is transmitting voice announcements: minutes 00, 08–10, 14–19, and 30. The voice announcements are rescheduled relative to WWV: Station identification is made during minutes 29 and 59 (vs. 00 and 30) GPS satellite health reports are transmitted during minutes 43 and 44 (vs. 14 and 15)
A fatal virus has been discovered in shrews in Alabama, sparking concerns about potential contagion to humans. The Camp Hill virus was discovered by researchers at The University of Queensland.
"The way I look at it is the virus can still surprise us," Jha added, noting that it continues to evolve. So instead of spending time predicting the chances of a new variant, or if the virus can ...
The virus is highly contagious; so contagious, in fact, that 90% of unvaccinated people who are exposed end up contracting it. Additionally, one in five of those people end up hospitalized ...
Watches receive the 60kHz signal from WWVB at Fort Collins. United Kingdom. Watches receive the 60kHz MSF at Anthorn. Germany. Watches receive the 77.5kHz DCF77 at Mainflingen. As an example, Casio Wave Ceptors using modules 3353 and 3354, such as the WVA-440, can tune to signals from both DCF77 (Germany) and MSF (UK).
The CDC released some new flu data to the public on Friday, despite the Trump administration’s halt of nearly all scientific communication coming from federal health agencies.
