    Radio Towers for Atomic Watches?

    I'm thinking of getting a skyhawk.
    Would i find the Radio feature useful in my Location? I'm in Vancouver BC, is that in range of a tower?

    Fort Collins' atomic clock in Colorado should be able to reach you.

    Information at http://www.c-maxgroup.com/tech/wwvb.php suggests that Vancouver is outside the optimum 2000km range from Fort Collins, but other googled coverage maps suggest that you'll be fine.
    Probably best to check with a Citizen or Casio dealer near you - if their radio controlled watches are working your Skyhawk will too.

    Here's some info that may help including coverage maps.

    I think you'll get a reliable enough signal most of the time for updates, keeping in mind the fact that the 'packet' takes a full 60 seconds. The watch probably polls once per 24hrs I'd guess, then operates at standard quartz til the next update. Even if it missed a few in a row you'll probably stay within 1 second or better. If you can tell the watch to poll at local true midnight, when signal propagation is best, you're nearly guaranteed it will work.

    One way to find out (virtually for sure) would be to get a desk or wall clock that uses the same technology before dropping cash for the watch. The desk units are very inexpensive and handy to have. Some (mine anyways) have an indicator to let you know of a missed update. Monitoring it would give you a good idea of signal integrity.

    Good luck.

    The signal is sent from Denver and is supposed to be received up to a thousand miles away. In practice it goes a good deal further, especially if your watch spends the night in a room tat faces more or less towards Denver. If you have any trouble, make sure that the 9 faces Denver because that's where the antenna is on just about all of them. I'm in St Louis, which is about a thousand miles. My room faces South and watches on the windowsill pick the signal up fine and so do some even when I sleep with them on.

    I don't think Vancouver would beany problem, but good luck, anyway.

    my radio clock is sitting at the window sill for like 10 minutes almost, the receiver even gave up. Looks like I'm not getting a signal.
