[time-nuts] Lady Heather and Lucent RFTGm-II-XO / RFTGm-II-Rb

If you can build the source code I can send you the latest version. Linux is easy to do. Not many people seem to be able to handle the Windows build but if you are familiar with Visual Studio (particularly command line builds) it is easy. Contact me off list for the code. I have figured

Re: [time-nuts] Lady Heather and Lucent RFTGm-II-XO / RFTGm-II-Rb

Mark, Have you built a special version of LH to work with the RFTGm’s? If so, is it possible to get a copy? Thanks, Rodger > On May 28, 2017, at 2:15 AM, Mark Sims wrote: > > I have Lady Heather working fairly well with the RFTGm's.I used a serial > port monitor

Re: [time-nuts] Next Aug 21 eclipse and time flow

Personally I go with the Nature article. The other papers look like they are anomaly hunting because they have a known event. Having said that, we have two H masers at our observatory in Hobart and we have a system set up to measure their phase difference down to about 0.03 ns. I will report back

[time-nuts] Next Aug 21 eclipse and time flow

On august 21 2017 a solar eclipse will sweep USA from coast to coast. A lifetime opportunity to do coordinated experiments to check this or that. One of the questions that doesn't have a final answer yet is whether or not solar eclipses could affect the flow of time. They exist conflicting

[time-nuts] Lady Heather and Lucent RFTGm-II-XO / RFTGm-II-Rb

I have Lady Heather working fairly well with the RFTGm's.I used a serial port monitor program to capture the traffic in and out of the serial port and used the Lucent control program to set and read various parameters. By analyzing the captured traffic and comparing the results to what the

Re: [time-nuts] Fwd: HP5061B Versus HP5071 Cesium Line Frequencies

Though I will never see a OSA 3000, It certainly sounds like a hack could be done to obtain a Cs off reference. But then when you don't actually have one you can make comments like that. Sounds nice. Regards Paul WB8TSL On Sun, May 28, 2017 at 8:20 AM, Magnus Danielson <

Re: [time-nuts] GR Connectors

GR made several coaxial connector series: the obvious 874, the 8.5 GHz very low residual VSWR GR-900 (IIRC 14 mm bore) and the GPC-7 (7 mm bore) 18 GHz precision connector, a very rare precursor to the APC-7 with a 1/4 turn locking collar, only place I saw it was in the HP 1965 catalog,

Re: [time-nuts] Two pieces of old General Radio Freq. Nuts

The GenRad 874 connector was good to 4.5 Ghz and took a Banana plug in the center conductor without changing electrical characteristics!!! http://www.ietlabs.com/pdf/GR_Experimenters/1948/GenRad_Experimenter_Oct_1948.pdf Not bad for a connector designed in 1948! It was largely supplanted
