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>.

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? 73 Bill AE6JV ----------------------------------------------------------------------- Bill Frantz | "The only thing we have to | Periwinkle (408)348-7900 | fear is fear itself." - FDR | 150 Rivermead Rd #235 www.pwpconsult.com<http://www.pwpconsult.com> | Inaugural address, 3/4/1933 | Peterborough, NH 03458 ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
