Re: [digitalradio] Re: What's with Boulder?
Aha! You said it. I looked up the WWV Time Codes at http://tf.nist.gov/stations/wwvtimecode.htm and it shows DST indicator #2 and DST indicator #1 as part of the code stream. When I used to build my own LED readout station clock that used WWVB time codes, those bits were not there.

Re: [digitalradio] Re: What's with Boulder?
Initially, I was thinking that the clock had the software to determine the change in daylight time and I think my La Crosse Technologies Clocks and my other atomic clock has a setting for this. But here in the U.S., didn't they change the DST data change? So, if the clocks changed accordingly, then it means that some kind of signal had to be sent. And two of my clocks changed. One clock did not change, but that is because I have it here in the shack and it is set to UTC:) The L.T. clocks are very nice units as they do a number of things, including remote detection of the temperature, relative air pressure (up or down), etc. And you can use one outdoor sensor for both clocks to detect. I have no idea how something like this can be sold for such a low price ($30, I think it was at Wal-Mart) and that includes an outdoor sensor for that price. Needless to say, I have a spare sensor if anything happens to the currently use one. They worked very well through this winter which is much better than when I had a much more expensive Radio Shack indoor/outdoor thermometer that never worked well at all. To put this in perspective, when I was growing up, it would have been total fantasy to suggest that someday there would be such a product and it would be sold for $5 (in 1950's prices). 73, Rick, KV9U jgorman01 wrote: My atomic clock changed right on time.

RE: [digitalradio] Re: What's with Boulder?
I have no idea how something like this can be sold for such a low price ($30, I think it was at Wal-Mart) Because they use Chinese prison labor to build them, probably. That's just ONE reason I don't shop at Walmart. But I certainly agree on the other aspects of your post -- These gadgets are amazing. de Peter K1PGV
Re: [digitalradio] Re: What's with Boulder?
Peter, A bit over the top for most reasonable folks. The majority of Americans shop at Wal-Mart except maybe a few on the fringe or extreme upper income. We shop at War-Mart because of the convenience of having everything in one place, even in a rural area where I live. Without them, I would be paying 20 to 30% more for many of our groceries and other products, or we would have to drive 40+ miles to La Crosse to find similar discounted prices. Not to mention being open 24/7 which was not available to us in the past. The La Crosse Technology products are distributed by the next door neighbor to a nearby ham acquaintance. They live just across the Mississippi River from La Crosse. You can buy La Crosse Technologies products from many sources. You are welcome to pay an additional $10 that you can expect to pay at full price stores or pay a lower price at a discount source of which Wal-Mart is only one. The point is that there is a lot of technology that goes into this kind of equipment, has a nice appearance, huge digital readout for even those of us somewhat sight impaired, remote sensor, etc. To call those in another country, slaves, does a disservice on an international group such as ours, and is also factually untrue. The standard of living continues to increase at a double digit rate in China although perhaps not quite as fast as it has been increasing the last decade or two. KV9U Peter G.

Needless to say, I have a spare sensor if I only have 1 atomic/WWV clock here and I bought it a couple years ago at CVS when they opened some stores and had special coupons for any purchase. I got it for practically nothing after the coupons, $5 I am sure. It is not especially fancy, but has time/date and indoor temperature. In amateur radio, I think, the market is fairly small and sometimes prices reflect it. In retail, special promotions, loss leaders etc can provide some bargains for related items that are general consumer products. I don't think it always has to be slave labor, etc to get a good bargain from time to time. -- Brian -- http://users.wildblue.net/k7on/ Blessed are the cracked, for they shall let in the light.

[digitalradio] Re: What's with Boulder?
There is a daylight saving bit in the data stream from WWV. It notifies your clock the shift is in effect. However the data stream continues on UTC time. Even though each time zone shifts at 2:00 AM local time WWV has to send one common signal to all. I can't find on their web site for which time zone they set the bit. In the U.S., clocks change at 2:00 a.m. local time. In spring, clocks spring forward from 1:59 a.m. to 3:00 a.m.; in fall, clocks fall back from 1:59 a.m. to 1:00 a.m. In the EU, clocks change at 1:00 a.m. Universal Time. In spring, clocks spring forward from 12:59 a.m. to 2:00 a.m.; in fall, clocks fall back from 1:59 a.m. to 1:00 a.m. In the U.S., restaurants and bars have various closing policies. In many states, liquor cannot be served after 2:00 a.m. But at 2:00 a.m. in the fall, the time switches back one hour. So, can they serve alcohol for that additional hour in October? The official answer is that the bars do not stop serving liquor at 2:00 a.m., but actually at 1:59 a.m. So, they have already stopped serving when the time changes from Daylight Saving Time into Standard Time. In practice, however, many establishments stay open an extra hour in the fall. Bill Ragsdale K6KN
