[Elecraft] [OT] WWV Time Transmissions

[Mike Maloney]

 Does anyone know any engineers who are hams at NIST, Fort Collins, CO?I be curious to know the RF loading coil and ground currents under the 0.024 wave stub  verticals for 5000M WWVB.

 Bill,
WWVB added a new modulation format starting around 2012/13 that includes a phase shift that some older clocks can no longer resolve. If you're technically inclined the internet is loaded with fixes for some older clocks as well as further information on this topic like <https://www.californiahistoricalradio.com/wp-content/uploads//2017/02/CHRS-Construction-BPSK-Dephaser-John-Staples.pdf>.

I had a friend ask me if something has happened to WWV's time
transmissions. He says the clocks in his home and his watch are
no longer syncing correctly. I think these are syncing to
signals at about 60KHz.

Does anyone know anything about this?
