[time-nuts] Spectracom 8170 Time of Day grief...(WWVB Clock)

[J. L. Trantham]

Well, it 'killed' my two.  The website for the manufacturer of mine (both
SkyScan, cheap from Sam's) stated that there was a problem with WWVB.

I'll keep an eye out for a replacement.

No, it killed phase-locking instruments, including the Spectracom clocks.
Most "atomic clocks" designed for time-of-day use do not, and never did,
phase lock to the WWVB carrier.  My 20-year-old Brookstone "atomic clock"
still works just as it always did (within tens of mS AFAICT).  So should
most other older "atomic clocks," and everything currently available from
the many time-of-day "atomic clock" suppliers.

Best regards,

Charles
