Re: [time-nuts] UltrAtomic clock.
We have a number of the UltrAtomic clocks in our Physics classrooms at Dartmouth in NH because they are in well shielded, interior rooms and a noisy environment. Lesser clocks do not sync. They all switched properly. Perhaps of interest, I was able to receive the new code reliably with an evaluation receiver in Kangerlussuaq, Greenland last spring.

( We're in northern Michigan, eastern > time zone.) Hi Dan, One of the advantages of the UltrAtomic clock is that it makes use of the enhanced WWVB encoding format. That new format is specifically designed to solve DST / reception problems: https://www.nist.gov/sites/default/files/documents/2017/05/09/NIST-Enhanced-WWVB-Broadcast-Format-1_01-2013-11-06.pdf So your results are perplexing. When you say "time has been right since it first set itself" are you talking within minutes, or seconds, or fractions of a second? That would tell us if it has been receiving ok over the past week or month. Also, can you check what your DST / Q-mode / Eco-mode switches are set to? http://www.lacrossetechnology.com/media/catalog/product/4/0/404-1235ua-ss_manual_092316.pdf Thanks, /tvb ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.

Re: [time-nuts] UltrAtomic clock.
Hi Dan, I can't answer directly as I am in England, but I have a similar problem with my MSF and DCF clocks here in the autumn (sorry, "Fall" :-) - my clocks only switch on their receivers once a day, at 1 o'clock in the morning, but at the end of summer our time doesn't change until 2 o'clock, so the clocks miss the update until the following night. Maybe yours is similar?

[time-nuts] UltrAtomic clock.
Hi all, So, anyone notice what time their UltrAtomic clock did the dst change? Mine didn't change last night. Time has been right since it first set itself, so, I'm suspecting it's getting signal. ( We're in northern Michigan, eastern time zone.) Anyone else have a clock that missed dst change?

Re: [time-nuts] UltrAtomic Clock
The successful rate of the cme8000 chip thats being used was something like 80-90% 24 X 7 from when I was logging it on the east coast. I was amazed as I have dealt with wwvb over many years. Its a shame that there is no access to some of the tidbits within the chip for tinkering. But then it does what it is designed to do.

[time-nuts] UltrAtomic Clock
When I got home after my Thursday Lunch meeting today, my new La Crosse 404-1235UA-SS UltrAtomic clock was waiting. I unpacked it and installed two (of 4 possible) C-cells and set it on the floor upstairs near the center of my home, fully under the radiant barrier insulation that has foiled (that's a pun!) all my previous "Atomic" clocks. The hands moved around 4 hours and stopped. I left. Returning about an hour later, the clock had set itself correctly! I verified the displayed time against my (Tindie) GPS Clock and the seconds and seconds-tick match as closely as I can determine visually. It's very unusual for these WWVB clocks to set during daylight. Normally, the 60 KHz WWVB reception during daylight hours is very poor indeed here on the west coast. These "atomic" clocks normally set to WWVB time in the several hours after midnight. That this new BPSK phase-shift modulation allowed reception under poor conditions is a big plus, especially for those with radiant barrier insulation and those who live on the east coast where the WWVB signal is weak. If you want to shop for this new clock, check Amazon for price: https://www.amazon.com/Crosse-Technology-404-1235UA-SS-UltrAtomic-Stainless/dp/B01CCHXTE2/ref=sr_1_1?ie=UTF8&qid=1491517516&sr=8-1&keywords=ultrAtomic+clock Better specs are on the La Crosse website here: http://www.lacrossetechnology.com/404-1235ua-ss-unltrtomic-analog-wall-clock It's kinda big, but I surely won't have any trouble reading it across a room! -- Best wishes, Larry McDavid W6FUB Anaheim, California (SE of Los Angeles, near Disneyland) ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
