[time-nuts] Efratom M100 Schematics

2017-11-05 Thread Ed Palmer
As far as I can tell, all online copies of the M100 User Manual are actually the same document. Unfortunately, the schematic and parts placement drawing for the Servo board don't match. For example, the parts placement drawing shows VR2 (voltage regulator) but the schematic doesn't and the

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

[time-nuts] Lady Heather DST change

2017-11-05 Thread Mark Sims
Lady Heather did the change, but triggered a hour early. D'oh! A while back I changed the way Heather kept dates and times internally from separate hh,mm,ss,month,day,year variables to keeping all times as double precision Julian dates. That change caused the DST code to not account for the

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. Bob > On Nov 5, 2017, at 9:23 AM, Dan

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

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
