Well I have lost 2 sharps one a while ago and now another that had been
working well until dst. Yes they are 4-5 years old but the xtals aren't all
that sharp and the gain in the TRF is pretty significant such that the xtal
can be off frequency and still work.
But the odd thing is there is an anten

I also have a SkyScan clock that is claiming to be synced to WWVB, but is
slowly drifting off. I've replaced the battery and it synced at least once
after DST conversion, Two other WWVB clocks are working as they should.

I found a note on the SkyScan web site itself that attempts to offer an
explanation/excuse as to why some of their clocks no longer synchronize:

This, however, is a BIG red herring.

If a clock uses a narrow (high Q)filter, the BPSK may mess up the
amplitude response. The Time Code is modulated AM on the carrier.
If this is the case, broadening the filter, possibly by adding shunt
resistance, might fix the issue.

The thing is, many of us on the opposite end of the country
from WWVB have to rely on favorable propagation to make our
clocks work reliably. What happens if noon and midnight
aren't favorable times?

Hi
So far all the WWVB stuff is running here. That includes my Casio wristwatch. I
admit that this thread convinced me to actually check it….

Interestingly, I have three timepieces that will no longer synch to
wwvb.Two Radio Shack digital clocks and a Casio wristwatch that I've
worn for a couple of years and was always pretty much dead on. Like

Funny you bring this up. I am just noticing a sharp clock that I always use
and it has been accurate. But it did not flip with the time change this

Someone pointed out a typo: I wrote model number "86716" where I meant
to write "86715" for the SkyScan clock in question. In the linked web
pages it is correct, however.
