Hi,
Unless you want to have fun building a clock, there are many such clocks
or watches out there. I wear a watch. Very accurate in time keeping.

Yes, I have one of these clocks also. The thing is, these clocks
are set 6 times in a 24hr perod by the WWVB signal. The rest of the
time the time base is an ordinary crystal. I want my clock to be
set on a more continous basis. This could only happen with the
continous decoding of the signal. This is how the "professional"
clocks, such as those made by Spectracom work.

You'll find that most of the schematics on the net for atomic clocks are
of the crystal variety-they set once or twice a day with WWVB and the
rest of the time use a crystal. You'll have to do some digging to come
up with something that does continuous decoding, but I'm sure it's out
there.


Hi,
That is just a WWVB reciever, ins't it?

Further, having owned one of these clocks for a brief period before the
holidays, WWVB doesn't have reliable coverage during the day (since it's
affected by the same propagation issues as AM radio, if not more so). The
clock I had (available at Sam's Club for about $25) set itself only once a
day, assuming it got a signal in one of six hours from midnight to 6am.
Maybe this is what was meant by "sets six times a day", but for what it's
worth, my clock's manual said it only set once, if successful, but tried up
to six times until it did.

I honestly don't see the advantage in running so close to the time
standard....if you want an accurate timebase, use the color burst signal
from a local TV station....their timebase is every bit as accurate as what
you'll get from WWVB, and most are available 24 hours a day. -- For direct
replies, take out the contents between the hyphens. -Really!-
