Re: [time-nuts] Fw: 5065

Yes. Thats an original. But someone posted on time nuts an alternate to amphenol and at a reasonable cost that was brand new. Thats how I came by my sets. I agree with Pete you do find them at hamfests in various condition. Regards Paul WB8TSL On Thu, Mar 17, 2016 at 4:04 PM, Pete Lancashire

[time-nuts] Unix software to generate nice looking *DEV plots

Moin, I'm looking for some non-GUI software to generate the different *DEV plots we generally use to asses oscillators with. Timelab is nice, but if you are evaluating two dozen measurements using different parameters, it becomes very tedious to generate the plots. Not to talk about the problem

Re: [time-nuts] Z3801A EEPROM

Magnus, Yes, I know that is how it works. I was just curious if anyone knew how and where that information was stored in the EEPROM. I thought it might be nice not to fool around with trying to set the date before it queried the satellites, to avoid the 1024 week issue. If I could update the

Re: [time-nuts] Fw: 5065

Most of the time I have seen the MS3106 style connectors used for power on mil spec applications. Does this one look like it is right? http://www.mouser.com/ProductDetail/Amphenol-Industrial/MS3106F14S-1S/?qs=sGAEpiMZZMv%2fye0hRulZR2pdaTIihrgU32yg4H0jMKs%3d If so, you should be able to get it

[time-nuts] How to run Lady Heather under Windows10

Hi, a new laptop and a new problem, I can not find COM1, and the slash command on Lady Heather provokes a response that spaces and slash marks are illegal in file names. Any ideas? thanks, Neville Michie ___ time-nuts mailing list --

[time-nuts] Difference between Oncore models

I understand that the Oncore GPS in the Lucent units is a newer module that tracks eight satellites, vs the older Oncore in the Z3801A that only tracks six satellites. I decided to do a re-survey with my Z3801A that has been in holdover for some time, just as a test. Watching the status screens

Re: [time-nuts] How to run Lady Heather under Windows10

There are multiple possible issues: 1) Most (like 99.99%) new laptops do not have a com port, that gets you to some sort of external port 2) USB is pretty common, but as mentioned in another thread, ethernet and bluetooth are also quite possible. 3) Since it is an external bus, the connection

Re: [time-nuts] Difference between Oncore models

Joe The newer Motorola VP-Oncore receivers are known to be an improved design over the original Oncores that came with the Z3801A's . I have recently done some side by side comparison's with two z3801A's on the same antenna the newer Vp-Oncore's ran SS numbers 15-30 points higher on the

Re: [time-nuts] Serial-Ethernet

Hi The graph is a nice way to see if there are any strange humps in the dac info when it is translated into frequency. We are used to looking at ADEV plots so it is not a bad way to present the data. If you have a unit that goes crazy every few hours, it will give you a bump on the plot. Bob

Re: [time-nuts] Serial-Ethernet

The Fury and other Jackson Labs GPSDOs can be put into manual holdover with the SYNChronization:HOLDover:INITiate command and taken out of holdover with the SYNChronization:HOLDover:RECovery:INITiate command. The phase measurement from the sync:tint? query remains valid while in the manual

[time-nuts] NIST quantum thermometer

NIST is working on a quantum thermometer. Apparently the current version is not very accurate, but they are working on it. If it ever comes to be, should be interesting... particularly when paired with their photonic thermometers.

Neville, I set up a shortcut to run Lady Heather on my Windows10 system, an old IBM ThinkPad. Here is the exact "target" command line I use in the shortcut to Lady Heather: "C:\Program Files (x86)\Heather\heather.exe" /4 Be sure to use the quotes exactly as they appear above before "C: and
