Re: [time-nuts] Lost GPS lock or 1PPS recently?

Hi all, discussion of how to keep accurate time without access to GPS seems very on topic to me. These people involved in major catastrophe ('end of the world' as you put it) scenarios have a wealth of experience in other ways of keeping accurate time. My 2c worth. John On 08/09/18

[time-nuts] Observations on how "Atomic" WWVB clocks set time

The Arcron Zeit clock does. It also has an RS-232 port. Lady Heather supports it (but calls it an Acron Zeit due to some typos in the original docs that I found and since there are maybe two people in the universe that still use them, I haven't had much motivation to fix that). At one

[time-nuts] Observations on how "Atomic" WWVB clocks set time

Now that I have my WWVB simulator up and running it's allowed me to experiment with the BALDR Model B0114ST clock I own. I've always been curious to observe what happens when it detects and set the time but, typically, this usually

Re: [time-nuts] Lost GPS lock or 1PPS recently?

Hi This is Time Nuts, not end of the world nuts ….. I most certainly did *not* design these systems. The *do* have timing requirements. If those requirements are not met, they stop working. That’s just the way it goes. Designing these systems at the timing level was done a decade ago. You can

Re: [time-nuts] Loss of NIST transmitters at Colorado and Hawaii

I don’t know if it’s on-topic or not, but my talking clock now has a WWV #define for the firmware. Mind you, all that really does is change it to 59 ticks and one beep and a single time announcement in the last 10 seconds of the minute. https://hackaday.io/project/28949-gps-talking-clock > On

Re: [time-nuts] Lost GPS lock or 1PPS recently?

You are SO convinced that GPS will ALWAYS be there, I’m NOT (Think Carrington Event) and i’ve been part of a few disaster exercises where both Internet and GPS were considered ‘down’ for the exercise and these exercises are done in conjunction with the military so PPS was also ‘off the
