89700 GRI is locked up nicely on the FS700. The Austrons are still searching for 99300 and 99600, the old Wildwood, NJ GRIs, no lock yet.

[time-nuts] Semi OT - TIP Use Vim to color code NTP.CONF
Hi all, Here's a neat trick I just discovered. If you like to put lots of comments in NTP.CONF, as I do, it's sometimes a challenge to find where the active lines are and where the comments are. I just discovered that, if you use the VIM programmer's editor to edit the file, all the comment lines are automatically color coded blue and all the active lines are color coded black. This makes it very easy to see the structure of the file. Not wishing to start a firestorm discussion of editors, you could use any programmer's editor that recognizes and color codes the lines with # as a comment. VIM is even smart enough to recognize in line comments after an active command. I've also extracted almost all my explanatory comments and put them in special sections with two blank lines before and after like so: # ### explanatory comments ### here's the theory of how the next commands work ### so on and so forth etc etc etc # That also makes it easier to read the file. See the following: http://dl.dropbox.com/u/9879631/vim%20sample%20image.png http://dl.dropbox.com/u/9879631/ntp.conf-normal VIM is available for almost any platform, including graphical versions, which I prefer. The graphical version for Ubuntu is called gnome-vim or is it vim-gnome in the repository, and gvim once it's installed. I have no idea if it works with Unity. http://www.vim.org/ Sincerely, Ron -- (PS - If you email me and don't get a quick response, don't be concerned. I get about 300 emails per day from alternate energy mailing lists and such. I don't always see new messages very quickly.

[time-nuts] A bit more on what going on with the Loran sites
From GPS World This week, UrsaNav once again transmitted from the former USCG Loran Support Unit (LSU) facility in Wildwood, New Jersey. To ensure that those interested understand that the USCG has no intent to acquire, operate, or provide a wireless time technology or services, UrsaNav has renamed the LSU — it's new facility name is the Diamond Beach Facility, or “dBF.” In a statement released today, UrsaNav said: Our main purpose for on-air testing at this time is to demonstrate wide-area precise time distribution using terrestrial, ground-wave RF solutions. However, a robust timing solution uses on-signal data channel(s) for nanosecond-level corrections, so we are also testing a variety of modulation techniques that provide significant throughput gains over the current 100-180 BPS methods. Our current equipment suites consist of the Nautel NL Series prototype transmitters, Symmetricom Timing and Frequency Equipment (TFE), and UrsaNav UN-150 eLoran Timing Receivers. We are not simply transmitting eLoran. We are also evaluating some improvements to eLoran that do not change the underlying signal structure. Finally, we are testing various alternative LF solutions that include new waveforms and modulation techniques. We have established preliminary monitor sites at five locations: Boston, Massachusetts; Chambersburg, Pennsylvania; Leesburg and Chesapeake, Virginia; and Charleston, South Carolina. We are scouting for additional monitor sites at distances of up to 1,500 miles from our current transmitting location. During this week’s testing, we tightened the synchronization of our transmissions to within 10 ns of UTC. We tested continuously for periods in excess of 24 hours. Without the use of any propagation corrections or differential monitoring, we successfully demonstrated UTC traceability to within +/- 30 ns at 160 miles and to within +/- 70 ns at 500 miles. Several acquisition trials showed that our receivers can very quickly acquire the LF signal and steer to within 50 ns of UTC. At all distances, our receivers met the ITU and ETSI Maximum Time Interval Error (MTIE) masks for Primary Reference Clocks. Additional on-air tests are planned for next week, so stay tuned for the third part of our continuing series on wide-area timing. ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.

[time-nuts] LORAN C testing Have to say seeing the offset drift all over
Been watching the LORAN tests and it used to be that the various austrons and SRS would settle to quite low offsets like the 12th after a while 24 plus hours. What I am seeing with the eLORAN is that at times the stability is quite good and working its way down. But then there are jumps and significant drifts at other times like 1 X 10 ^ -08. Fairly gross. Now I see its off the air again Oh well thats the way it goes. Back to the Tbolt and GPS.

It sounds like a GRI thats been spread and perhaps this is what a GRI sounds like when you do lots of phase reversals. My O my time to fire up the old austron 2000 gate a scope and see if this junk is synchronized. Have to believe I can do the same thing on the SRS FS700.

Re: [time-nuts] LORAN modulation scheme???? Kind of interesting
Well its interesting. The dana site was up I would say quite loud about 1900 EST until 2200 I think. But the stuff I was hearing is local garbage I believe now.
