"Atomic" clock for UTC/GMT?

Panzer,

Thanks for the effort, but I was looking for a completely separate
clock, not a computer program. I already have several of those!

Some of the MFJ atomic clocks might work -- check their web site.

Father Mike, Glenn, and Robert,

Thanks for the solid information and sources!

BTW, I actually do have a GPS clock for my computer. It works great,
but I wanted something which I could keep in the shack which didn't
require the computer to be up. My ancient Heathkit digital clock died
after 20+ years, and I thought I would replace it, and opt for
something I didn't have to hack with WWV every time the power failed.

Well, I have seen gps units interfaced to a mcpu and lcd display that shows gps
info, which can also be time in any format you want.. 2 displays whether lcd or
led can be set up from the same mcpu "Basic Stamp". It is very do-able and
should be low cost "under $100" for sure... i can easily do it with what I have
in the shack... I also sold one of those cell-site reference gps-time units for
a bunch of $$$ that I only picked up for $55 bucks a few years ago...It would of
been the best thing for a shack time reference unit..

So looking at those cheap clocks in the discount stores might
bring you the same sort of deal. Good luck!

I have bought two flavors of WWV-synced clocks recently at the big box
stores. One was a small unit (2-inch display) and the other was a large
analog wall clock. Both of them work great, even though one is on an
interior wall in the basement. I'm truly amazed that they can hear WWV
and yet the cost was under $20.

Likely because they aren't "WWV-synced".

While in the past there were some clocks that got the time in digital
format from WWV, the more recent wave of "atomic clocks" receive WWVB
at 60KHz. The low frequency allows for strong propagation throughout
much of the day, and penetration where higher frequencies might
get shielded out.

Well Dunno but I have 2 of the big ones digital also displays
indoor and outdoor temp. They are fed by wwvh just one island
away from me on Kauai. I have no problem it stays locked
right to the second. Once in a while the Kauai WWVH goes down
on both 5 and 10 mhz for hours if not days. Then the 2 clocks
loose it of course. WWV on the mainland is almost inaudible
out here most of the time except if conditions are good the
15mhz sig comes thru fairly well and the clocks sync on it.
