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? Dan -- Sent from my phone.

 I can't answer directly as I am in England, but I have a similar

 Regards,

      Peter

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?

Hi All of the ones here (a fairly large sample :) ) seem to have changed “on time”. I’m in Pennsylvania so not exactly close to WWVB. They are various brands and various ages. None of them (yet) are the fancy new ones that do the “improved” modulation.

My Ultratomic properly made the transition back to std time this morning. I am in the Boston area.

( 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

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.
