Re: [time-nuts] Need Time Help
I must admit to being rather puzzled at the sub microsecond timing requirement as I use ntp to set the W7 clock in my computer and have not had any issues. In fact less than one second is OK for the usual two minute periods that are required to allow for the Faraday rotation. Although I use a GPSDO for a frequency reference I find JT software reasonably tolerant of frequency. As I may be missing something I would welcome observations on how important the period timing requirement is, you never know I might get more contacts.

He is trying to time synchronize a system, where the other station he is communicating with can be any other place on the Earth that can also see the Moon. So the system time sync is for a little bit tougher case than a local area network. --- Graham ___ 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.

Dave, The rules have changed regarding photography for all National Trust properties so click away. Regards Peter On 07/07/2016 21:41, Dave Martindale wrote: Hmm. When I was there yesterday I didn't see any "No Photography" signs, so I photographed lots of the exhibits, including the four Harrisons . I used flash, so I wasn't the least bit stealthy, and one of the staff was only a few feet away. Maybe they no longer care?

Re: [time-nuts] Visiting Greenwich
The original speaking clock ( in use from 1936 to 1963) has been restored to working order and is on show at the British Horological Institute at Upton Hall near Newark (UK). Speaking clock N0 2 that replaced No 1 is quartz controlled and also on view at Upton hall. If anyone would like details of them just let me know.

I suspect this predates the one under discussion? I also have a two part article on the Mark 2 built in the UK for Australia.(mid 1950s) DaveB, NZ ___ 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.
