Re: [time-nuts] The ultraAtomic clock for home

Hi I’m sure it would have happily corrected for summer time in Europe two weeks later …. Provided (of course) it got the switch codes from DCF77 to tell it when to do so. My guess is that the tiny little watch antenna isn’t very good picking up time code from the other side of the Atlantic :)

Bob, if you had your watch set to European time, could the fact that Europe changes to daylight time about two weeks after we do in North America have anything to do with it? ... Martin VE3OAT Bob (KB8TW) wrote : On a side note, my Citizen WWVB watch missed the change to DST this year. I

Re: [time-nuts] The ultraAtomic clock for home

Yes its quite common. The clocks are always off by sometime and generally never account for winter and summer time. Lastly ooops the ole batteries dead or corroded. In Broadcast facilities all of the clocks are actually driven by synchronized time codes. Either LTC or IRIG. The clocks can be

Re: [time-nuts] The ultraAtomic clock for home

In the office where I work, they have 5 clocks on the wall showing local time here at HQ and at 4 other company sites. It is embarrassing that the clocks are always a few minutes off from each other. I can see where these would make sense. Rick N6RK On 4/5/2017 4:30 AM, Bob kb8tq wrote: HI

Hi The Lacrosse wall clocks I’m using now are hybrid analog / digital displays. You get the time analog and the date off the digital display. For whatever reason, that model is now history. Bob > On Apr 5, 2017, at 11:30 AM, Richard (Rick) Karlquist > wrote: > >

Re: [time-nuts] The ultraAtomic clock for home

Why? oh why? is this only available as an analog clock?? I am wondering if Lacrosse only has the rights to an analog version and that a higher priced digital version will show up in some "professional" line from another vendor. This is at least a plausible theory because this is a well known

Re: [time-nuts] The ultraAtomic clock for home

Will say that is pretty interesting that it takes either 2 or 4 c cells. It appears they parallel the C cells for more time. In eco mode 2 batteries 3 years or 4 batteries 6 years. Run time will vary depending on the batteries leaking in 3.5 years. At least it seems that way today. (Not to trigger

I have had a Stauer Titanium Atomic wristwatch for 6 years. Never had a problem. Never have had to set it. Still on the original battery. Automatic DST. Analog dial for hours and minutes... digital display for seconds and month/date. It is always in step with WWV... ;-) 73 Don W4WJ

Re: [time-nuts] The ultraAtomic clock for home

Really can't say that its c-max or not. Since if you try to download anything from the sight the links are dead. But I do believe its the true wwvb bpsk decoder. If it is the cme 8000 that chip works impressively well even in New England. But this is the first time I have stumbled across anything

Re: [time-nuts] The ultraAtomic clock for home

I have been happy with the Casio Waveceptor watches. They can display UTC. They seem to reliably set themselves between midnight and 3AM each morning when I'm wearing them here in Maryland, more reliably than the (non-PSK) WWVB wall clocks. The Casio WV58A-1AVCR is a plastic LCD watch for $28
