[time-nuts] Symmetricom X72 and Lady Heather results

2017-07-28 Thread Mark Sims
I'm in the process of adding support to Lady Heather for the Symmetricom X72 (and SA22) rubidium oscillators. I have a most of the functionality working. The X72 has a "health" message that dumps a couple dozen values. The values are labeled with some rather cryptic names that give some hint

Poul I looked at your site and the power supply. That makes a lot of sense. Though I have not lost my transformer as Ulf has at least I see an answer that I can use. I would have come up with the same approach but you did the thinking for me. Thanks Paul WB8TSL On Thu, Jul 27, 2017 at 3:58 PM, Pou

Interesting. What about NTPD implementations, when using a TB as the reference time source? Does that handle the week count roll over as well? If that was added, from what version? I suspect I may have some updating to do! I use a TB as a frequency ref' and local NTP/NTPD server reference. T

Well I did some research and found my new best friend! If you remember I needed: "I have a square aluminum tube 5" X 5" with a .25" wall it's 8 1/2" long. I need 20 holes in each end tapped for 4/40 and 1/2" deep." This for a Rubidium standard I am working on. I found all about self forming ta

Forgive my naivete, but if this is something as simple as the t'bolt adding a 10 bit number to a base date, could not the base date be changed in the PROM? (Presuming one can get to it, etc) Though I suspect that might not be all that simple of course. And I'm not taking mine apart to look. :) On

Good even for mild steel too. Best is your good advice to use the drill press to keep the tap aligned. softer aluminum alloys are very "sticky" and demand backing off a turn for almost every turn forward for cutting taps to break the chip. I've found that the 6/32 tap is the most easily broken

It appears there is no command to set the current time in the Thunderbolt. Too bad. I have some very old Garmin OEMs (GPS35) that work fine as long as I set the time and date to be close. I just had to do a RAM reset ( $PGRMI,,,C ) on one which had gotten corrupted and would not report
