Re: [time-nuts] Interesting paper: Don't GPSD' your Rb...

The paper should really be titled Another way to discipline your Rb to GPS. Wouldn't it make more sense given the phase noise in the Rb to base your correction on a moving average diffence. 1) Reduce the Rb phase noise 2) Carefully make it a multiple of a day to cancel diurnal effects of the

Re: [time-nuts] NTP jitter with Linux

I found that the AMD processors change CPU frequency with load and this seemed to upset any NTP calculations. In the end I went to Intel CPU (Mutter mutter). Regards Randall -Original Message- From: time-nuts-boun...@febo.com [mailto:time-nuts-boun...@febo.com] On Behalf Of Mike S

Re: [time-nuts] NTP jitter with Linux

real time, i.e. lower latency. I never messed with them, but you find this mentioned related to multimedia oriented distributions. On 4/4/2012 3:53 PM, Randall Prentice wrote: I found that the AMD processors change CPU frequency with load and this seemed to upset any NTP calculations

Re: [time-nuts] Best reason

People can all relate to their cellphones. Just tell them that the cellphones all yell at each other but not at the same time so as long as you know when to listen you can hear the other end. :-) Regards Randall -Original Message- From: time-nuts-boun...@febo.com

Re: [time-nuts] fluke.l monitor for Thunderbolt

Mine stopped the same way. I gently spread the boards apart and unsoldered the 3 pin regulator then added a Red-LED in place of the three links (Original circuit had three diodes) and my monitor starting working again. So it may be recoverable. Regards Randall -Original Message- From:

Re: [time-nuts] fluke.l monitor for Thunderbolt

Sorry, I didn't give credit to you Arthur. I was following your instructions. My post was also to the effect that it all started going again afterward inspite of such bad treatment (Over voltage/Over heating). The other point omitted from my post (Obvious afterward), was that removing the

Re: [time-nuts] Question about SoundCard stability?

1 Hz in 10Mhz is about the same ratio as 5mHz in 64Khz. This would make sense if the Clock for the A/D is divided off the same TXCO. Or am I missing something. The reason I jumped in, in a recent frequency measuring contest the winner was using that interpolation for his results. Regards
