STAMPERS:

Has anyone out there interfaced a WWVB/WWV clock to a
STAMP II. The Ultralink clock offered is no longer
available, so that is no longer an option! Is there a
current substitute clock?
thanks
Tom

    Maybe you could hack one of the WWV clocks they sell various places for
    $20-40?

    The only thing I found was this:
    http://psn.quake.net/sdrdocs/wwvcorr.htm

    The Canadian version of WWV actually sends out a 300 baud modem FSK signal
    at regular intervals.
    Which is the same signal they send out when you dial in on their data lines.
    So one could feed the audio into a modem to get the signal decoded into a
    serial stream.
    But you have to be up near the Canadian borders to be able to receive this
    radio signal.

    The signal from CHU is Bell 103 compatible. Full details are here:
    http://www.nrc.ca/inms/time/chu.html

    The broadcasts on 7335 kHz and 14670 kHz should be receivable anywhere in
    the USA, though maybe not 24 hours a day. 7335 would tend to be better at
    night while 14670 would tend to be better in the day. Both of them are
    clear as a bell at S-6 on my signal strength meter as I type this at about
    9:30 AM. I'm located in South Carolina and have a ground mounted vertical
    antenna. A 3-foot whip sticking out of the radio won't work as well, but
    it should work as well as any "Atomic Clock Radio" that uses the WWVB
    system based on 60 kHz out of Fort Collins, CO. Info on WWVB is at:
    http://www.boulder.nist.gov/timefreq/stations/wwvb.htm

    Here is something I found poking around the link that was sent -- a list of
    WWVB and other time receivers.
