Re: [time-nuts] Furuno GT-87
Hi I wonder if they will ever get around to dropping the “Galileo with firmware update” statements from *all* there spec sheets for the GT-87 and Opus-7 devices…… There has always been the basic issue of *how* an end user would be able to get such an update. Furuno does not seem to have a channel for distributing that sort of thing.

[time-nuts] Furuno GT-87
I re-confgured the GT-87 to just use GPS satellites (the posted data had GPS, SBAS, and GLONASS enabled). The 1PPS span was mostly +/- 2.5 ns, with a few excursions to the +/- 3.5 ns range. I'll try GLONASS only next. I looks like Furuno is not going to add Galileo support to the GT-87 firmware. ___ 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] EFTF 2018
Speaking of forums etc, does anybody in Time-Nuts attend anyof the NIST Time and Frequency Seminars? I'm wondering if I'd get much from it. I've thought about doing so for years, but never got around to pushing for it while employed. Now it's looking awfully expensive.

To my best knowledge, neither Bathys nor Hoptroff are making CSAC watches anymore. Ronald ___ 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] Suggest time-and-tech related locations in Switzerland
There is a Laser Ranging station in Zimmerwald which is related to METAS. They measure distance of artificial satellites down to few millimeters by fly time of sub-nanosecond laser pulses, so they have very accurate time-interval measurement systems. There is also a nice Museum d'horlogerie in Le Locle, near Neuchatel : https://en.wikipedia.org/wiki/Le_Locle Best regards, Jean-Louis On 15/03/2018 12:22, Pete Stephenson wrote: Also worth mentioning is the Swiss standards organization, METAS, in Bern. Their time and frequency group has a few atomic clocks, a maser, and some other shiny things they use for realizing UTC(CH), as well as a few research projects related to the subject.

I am not familiar with museums in that area, but I am sure there are some. I think someone else on the list will have more details. The whole area is the so-called "Swiss Jura". The area of time & frequency companies and institutes extends into France up to Besancon. Neuchatel and Besancon are the locations where the EFTF (European Time and Frequency Forum) started and is taking place in one of both every two years.

[time-nuts] EFTF 2018
Hi, As I just registered for EFTF 2018, just wanted to check if any fellow time-nuts would join me there. I can also be expected to show up on the IFCS-EFTF 2019 conference, as I will serve on the JTPC for it.

Hello Dave, being 'time-nuts', it is of course to know the time of day to the nanosecond! That said, I truly believe there are only two wristwatches out there for the serious time-nutter: https://www.kickstarter.com/projects/846511652/the-worlds-first-true-atomic-wristwatch-the-cesium/updates and of course the well known TvB wristwatch: http://www.leapsecond.com/pages/atomic-bill/ 73s Achim, DH2VA ___ 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.
