Re: [time-nuts] Tardis [WAS: Using the HP 58503a to correct your PC clock]

That's encouraging!! I'm working on NTP and have no idea what's happening. The description says it takes over the PC clock, excluding other apps. I like the rate correction concept, but not if I lose my hair or have to wipe the drive. Ron From: Charles Steinmetz

[time-nuts] Looking to find an antenna for a TrueTime XL-DC

I have been bequeathed a TrueTime XL-DC, Model 151-601-1, serial number 1671 per a sticker on the side. On the back, on the right as one faces the back, is a small sticker that says "Down Conv. Req'd" Unsurprisingly, it has arrived without an antenna. If the original antenna still exists,

Re: [time-nuts] GPS antenna selection

Hi Herbert, just look the loss of the cable at 1500 MHz, and you will start to cry at 1500MHz tha cable will have cca 30dB for a 30meter long piecebasically that RG174 looks very nice with that small antenna but that is the only positive aspect. Meinberg in Germany has one up/down

Re: [time-nuts] Using the HP 58503a to correct your PC clock

The old Tardis program for Windows (Tardis2000 now) handles it correctly by altering the rate and only jamming the time if it is outside of a specified window but I do not think its GPS mode supports the 1 PPS signal. I am not sure if Tardis works with Windows 7 and above though; I forget to test

[time-nuts] Using the HP 58503a to correct your PC clock

Probably the best way for most people to keep their clock accurate is to use something like NTP with a local GPS receiver that provides a 1PPS signal that you can get into your computer (not always an easy thing to do and get working properly). Done properly, this can get you into the

Hi, I'm in the process of setting up a public stratum 1 NTP server which will have at least one standard as a fallback to GPS (and possibly WWV and CHU), in addition to its primary purpose as a timebase for a microwave active SETI transmitter. So far I have an aging = 1E-11 rubidium standard

Thanks. Although I'm brand new here, I've seen some posts talking about Lady Heather (some with amusing suggestions) and will look into it. Might just be what I need. I'm working with NTP right now, using Dimension 4, after having discovered D4's history info. Thanks again, Ron From:

Re: [time-nuts] Using the HP 58503a to correct your PC clock

The WRONG way to adjust a PC clock is to set the TIME periodically from some standard. When you do this then the time on the PC is not running at a constant rate. The correct way to do this is to adjust the PC's clocks RATE. You make it runs slightly faster if you notice it is getting behind
