[Courtesy of Matt Deutch, N0RGT]"The antenna the 25 MHz [transmitter] is on right now is the original antenna it was on in 1977," Matt Deutch, N0RGT, WWV's lead electrical engineer, told ARRL. "When the 25 [MHz transmitter] was shut down [that year], the radiating section was removed and tossed in the bone yard, and a new longer section put on the tower to make it a 15 MHz stand-by antenna." Deutch said that when WWV first reintroduced the 25 MHz broadcast in 2014, it used a broadband monopole. It was later decided to use that antenna for WWV's 2.5 MHz stand-by transmitter, though. "So, we decided to rebuild the 25 MHz antenna,"

Deutch said the variance in the Earth's rotation is largely due to the moon's gravitational pull on the Earth's oceans."The moon's pull on the tide is actually acting as a break on the earth and slowing it down," Deutch said.The current difference between the ultra-precise atomic clocks and the earth's actual rotational time is 2 to 3 milliseconds per day, according to the NIST.Another factor according to Deutch is the land mass of the Northern Hemisphere, which accumulates large amounts of snow in the winter and acts as a break.Deutch used the analogy of an ice skater spinning in circles.As the skater moves
Matt Deutch from NIST this week wrote in an email, "I want to assure you that nobody has any intention of discontinuing the WWV/WWVH broadcasts.We are doing a survey as a periodic check (roughly every 15 years) to see how many are using our service and if we are meeting their needs."
