Re: [time-nuts] TS2100 OCXO Conversion: Command exploration

[Bruce Lane]

And, as of today, I still can't get it to lock. :-P

I think I'm going to have to conclude, reluctantly, that the full-size
OCXO's are simply not compatible with this unit. It strikes me as
possible there may be other hardware changes needed to run such. It's
just impossible to tell for certain without some kind of schematic.

So -- Reverse conversion, here we go. Looks like I'll just have to
settle for a square wave until I can find a couple of MTI 240's

Thanks to all who rendered assistance.

[time-nuts] TS2100 OCXO Conversion: Command exploration

[Bruce Lane]

Fellow Time-Tickers,

I'm still experimenting with conversion of the TS2100 from standard TTL
oscillator to OCXO. More specifically, the OCXO I'm trying is made by
the now-defunct Piezo Crystal Company, Carlyle, PA. It's their model
2900082-47, and from what little I've been able to discover, it seems to
match the large 'U56' pattern in the 2100. It is said to be a direct
replacement for the Trimble-branded 37266, so I'm hoping its EFC voltage
is in the 0-5V range.

I've made much progress in deciphering the menu structure of the 'root
eng' section, thanks to past posts from Greg Dowd and others. Permit me
to explain, for the benefit of those who may be having trouble making
the 'intuitive leap,' as it were. Please note, everything I'm describing
here is done with a hardware RS232 connection directly to the unit, on
P4 - Serial port B. Comm parameters used were 9600-8-N-1, no flow control.

Symmetricom, apparently, used single words as commands. Anything
following the first word in a command list, unless clearly called out by
an underscore (as in the command 'eeprom_select') is merely descriptive
commentary for the command itself.

Here's some examples. We'll start with the command 'root' (minus the
quotes, of course). If you type 'root' and simply hit enter, nothing
appears to happen. However, if you type 'root ?' and hit enter, you get
this:

Commands

network /
timing /
serial /
utility /
intrinsic help


This is indeed the visible 'root' level of the command directory. Note
the valuable (to techies) 'root eng' is hidden. Type that command, add a
question mark at the end, hit enter, and you get this:


Commands

start net interface
timing tools /
serial tools /
eeprom tools /
spi tools /
flash tools /
display tools /
memory tools /
intrinsic help


Type 'root eng eeprom ?' and hit enter, and you get:


Commands

ethernet address
board serial number
gain default
filter constant
low filter constant
precision
set eeprom
get eeprom
read serial eeprom
write serial eeprom
tx 16 bits to eeprom
location for image
info value
eeprom_select
intrinsic help


Do you see the pattern? The first word, and only the first word, is the
command and whatever you type after that is what value you want entered
as part of the command. The question mark shows a list of commands
available under whatever section you're in.

Example: Type 'root eng eeprom gain' and the far left column will show
you what the current gain setting is. Type something like 'root eng
eeprom gain -20' and your gain will be set to -20 and the value stored
in the EEPROM.

Now, here's the fun part. Remember how I'd originally asked about
changing the D/A value, and I couldn't seem to get the syntax right? As
I recall, other list members have had similar issues.

Check this out: Type 'root timing utils ?' and hit enter. You get:


Commands

tfp data
jam sync
force jam
phase on
adjust time
generator offset
gain adjust
filter constant
low filter constant
diff value
d/a load
leap second utc
reference time
cmp delay
intrinsic help


Now, try this one: 'root timing utils d/a' and hit enter. Here's what I
gor:

D/A value (0x - 0x) now:0x178

Next, I tried: 'root timing utils d/a 0x180' and hit enter. Lo and
behold, when I queried the value again, I got:

D/A value (0x - 0x) now:0x180

So -- That's how to set the D/A constant in the beastie!

Now, with all this said: I'm still waiting for a 'Lock' indicator on
the front. It's tracking, and the D/A value certainly has changed from
what I had it at last night, but I'm still not getting a lock. Here are
my current numbers:

root timing utils tfp 0 -- returned 0x00f2
root timing utils tfp 6 -- returned KM = 0.9994965
root timing utils tfp 7 -- returned KO = 0.9994965
root timing utils gain -- returned gain now:20 (There seems to be a
difference of opinion as to whether -20 or 20 should be used. At this
point, I'm tempted to just set it to zero and see what happens).

root eng eeprom info -- returned 0024

Any thoughts on why I don't have a lock as yet?

And -- I hope this helps out others. Thanks much!

[time-nuts] Weird Stuff Warehouse shutting down

[Bruce Lane]

Fellow techies,

I'm sorry to report we're losing another surplus place. Weird Stuff
Warehouse, in Sunnyvale, CA, is closing its doors as of Monday, 9-Apr-18.

It seems we have Google to blame. Here's Weird Stuff's final
newsletter, verbatim.

-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

April 6, 2018

To Weirdstuff Customers,

Sadly, after 32 years in business, Weirdstuff Warehouse will be closing
its doors as of April 9, 2018. If you have been following the real
estate news for Sunnyvale you know that Google purchased a large amount
of real estate in the area including the building we have been leasing
for the past 22 years. We have been asked to vacate the building as soon
as possible, and in order to accomplish that task we are selling our
inventory and many of our assets to Outback Equipment of Morgan Hill.
The transfer of inventory and assets will take place on April 9, 2018;
at that time Weirdstuff Warehouse will cease to do business.

Even though Weirdstuff is closing we will retain ownership of the
Corporation, trademark, and domain names. We hope to handle these
entities and wind down the corporation before year end.

Many of you have been loyal customers for many years, and we have
enjoyed working with you. We thank you for your loyalty and business.

For more information, check out our website after Monday, April 9, 2018.

WeirdStuff Warehouse
384 W. Caribbean Dr.
Sunnyvale, CA 94089

[time-nuts] TS2100: List of root commands?

[Bruce Lane]

Fellow time-tickers,

I just finished conversion of one of my TS2100's to OCXO, and I'm now
in the process of tweaking the EEPROM settings.

During my research, I came across (and, foolishly, didn't bookmark)
either a web page or a mailing list post which listed the 'root eng'
commands, and exactly how to enter them. I've been successful with 'root
eng ee gain' and 'root eng ee filter,' but I can't seem to get the
syntax down to set the D/A value.

Does this sound at all familiar?

Thanks much.

[time-nuts] TS2100: From regular xtal to OCXO?

[Bruce Lane]

Fellow Clock-Tickers,

I've got a pair of Symmetricom TS2100's, both of which have the basic
TTL oscillator module for their reference oscillator. As other owners of
these units are probably aware, the board is also laid out for a couple
of different types of OCXO.

I've got what I believe are the correct OCXO's coming from an Ebay
vendor. They match the source voltage (12VDC), the control voltage
range, and the pinout.

My question is, do I need to make any configuration changes to the
2100's, in terms of jumpers or anything? Or is it literally a case of
swap-and-play?

    Thanks much.

[time-nuts] TS2100: Which OCXO's work?

[Bruce Lane]

Fellow time-tickers,

My thanks to Greg for getting back to me (and apologies for the spam
filter bounce) but, apparently, MTI 240 OCXO's have become unobtanium.

With this in mind: What other OCXO's are compatible with the
Symmetricom TS2100? My understanding is whatever I choose would need a
12V oven circuit and a 0-5V tuning control input.

Suggestions?

Thanks much.

In the interest of presenting alternatives -- I dumped Dropbox a while
back, due to their increasingly invasive 'privacy' policies.

A good alternative for me has been Sync: https://www.sync.com/

Their 'Free' package includes 5GB -- More than I would ever possibly
use for an online sharing account. ;-)

[time-nuts] MTI 240 OCXO, anyone?

[Bruce Lane]

Happy New Year, fellow time-tickers!

Would anyone happen to have a spare MTI 240 series OCXO, 10MHz output?
I'm looking to upgrade my TS2100.

Failing the MTI, what alternates will work? I'd be very surprised if
Vectron didn't have an equivalent.

Thanks much.

[time-nuts] TS2100: Upgrading oscillator?

[Bruce Lane]

Good day,

During recent repair efforts on my Symmetricom TS2100, I noticed the
main PC board has silkscreening, and hole patterns, to cover different
types of crystal oscillator.

Might it be possible to upgrade from the standard unit (a DIP-14 form
factor clock oscillator) to, perhaps, an OCXO?

Anyone have a 2100 they can share pictures of? Or, perhaps, one which
has been upgraded?

Just wondering...

Thanks.

[time-nuts] Updated GPS board for TS2100

[Bruce Lane]

Fellow time-trackers,

I found myself having to replace our network time server this weekend,
specifically with a "new"/used Symmetricom TS2100 'TymServe' unit.

When I first got the 2100, it had the week rollover problem, of course.
However, some creative web searching led me to this site:
http://www.heoldesign.com/

More specifically, it led me to this product:

http://www.heoldesign.com/N024-GPS-receiver-board-for-Tymserve-2100

Normally priced at just under USD $180, I got lucky and got mine on
sale for about $132 (works out to 120 Euro). This board was, quite
literally, a drop-in replacement for the original. Four screws out,
unplug the antenna, plop the new board in and power up. About 40 seconds
later, it started tracking and registered the correct time/date. A
couple of minutes later, the disciplined oscillator output locked on.

I would not hesitate to recommend Heol as a source if anyone else has a
rollover-wonky 2100. They also make a drop-in replacement for the
Trimble Lassen and ACE series.

Did I mention outstanding customer service?

Keep the peace(es).

[time-nuts] TrueTime NTS-100: Firmware?

[Bruce Lane]

Fellow Time Travelers,

My TrueTime NTS-100 just got hit with the GPS date rollover bug
(started showing dates in the year 1997).

Does anyone have, or know of, an appropriate firmware update for this
beastie? Or is it time to recycle the thing?

Would replacing the GPS receiver board cure it? The unit seems to be
using an older Trimble unit (I'm guessing one of their 8-channel boards).

Thanks much.

Fellow Clock-tickers,

Has anyone ever found a PDF of the manual for the Datum/Symmetricom

[time-nuts] GPS Timing antennas, NIB

[Bruce Lane]

Good day,

All the recent talk of coax types and antennas reminded me. There's a
seller on Epay (rdr-electronics) who has a whole stack of Lucent-tagged,
high-rejection rated (as in spurious RF emissions) timing antennas at
what I thought was a pretty good price. I bought three of them last week.

Item number is: 231917475470

One of the nicest things about these units is they will, apparently,
run on any DC bias from 3.3-12V. Two are going in to replace my older
antennas, and one is going on my test bench.

No relation to the seller other than being a very happy customer.

Keep the peace(es).

Re: [time-nuts] RG6 or LMR400 for GPS Antenna (Symmetricom 58532A and T-bolt)

[Bruce Lane]

My $0.02 worth.

If the cable is going to be exposed to sunlight and weather, long-term,
be sure you get a cable type rated for UV exposure (polyethylene
jacketed). If you really want to get something rugged, and you don't
mind removing a bit of citrus-scented goo, go with 'DB' (Direct Burial)
suffixed cable (Example: LMR400DB).

Whatever you do, DON'T use the cheap PVC-jacketed cable! Sunlight eats
that stuff for breakfast.

Happy tweaking.

Re: [time-nuts] Can a Symmetricom 58532A antenna and ham radio transmitters coexist?

[Bruce Lane]

I have multiple GPS antennas, an HF ground plane and a long wire. I
typically run no more than 100W on HF, but am capable of pushing to 500.
All the antennas are within 30-40 feet of each other.

Personally, I've never had an interference problem between any of them.
I use LMR240DB (Direct Burial) for the GPS runs, and LMR400DB for the
HF's. Yes, the filling goo can be a hassle, but at least it is easily
removed with the citrusy-smelling solvent (darned if I can remember the
name of the stuff at the moment). The extra water protection and UV
resistance are well worth it, at least to me.

If you're really paranoid, rdr-electronics on Ebay has lots of NIB
High-Rejection rated GPS timing antennas, made by PCTel/MaxRad for
Lucent. They are expressly designed for use in high-RF environments and
contain extra filtering.

The item number would be 231898765036, going for $30 + shipping last I
looked. The manufacturer part number is GPS-TMG-HR-26NCM, Lucent P/N
KS24019-L112D, ComCode 849143987. The collar takes a 1.5 inch mast.

No connection with rdr on my part, other than being a very happy
customer of theirs for the last several years.

Keep the peace(es).

[time-nuts] OEM 5000 Receiver module available

[Bruce Lane]

Fellow Time-Tickers,

Anyone need a spare Magellan OEM5000 GPS receiver module? I was
cleaning up yesterday and I found one I had as a spare (for when I still
owned an Odetics 425). It's missing its antenna input connector, but
other than that I think it's OK (granted, I don't know for certain).

Let me know. If no responses, it goes into recycle next week.

Thanks much.

Re: [time-nuts] Acquired a Symmetricom 5817A-05Q / Power connector Question

[Bruce Lane]

Honestly, that looks broken to me. And, it looks more like a broken SMA
jack (at least from the photos).

I would say your best bet is to open the thing up and replace the
connector with something a bit more workable.

Happy tweaking.

[time-nuts] Z3812/KS-24361 PDF?

[Bruce Lane]

Looks like Symmetricom got bought out by Microsemi. A search on
HP/Keysight's site shows only an entry which says the Z3812 is long
gone, even from their archives.

So -- Anyone know of a manual for the thing?

I would add, from initial observations of my unit: It looks like it
might be possible to add a GPS module to the backup unit and end up with
two independent GPS standard units (at least that's what I gather from
comparing the PC boards).

Keep the peace(es).

Re: [time-nuts] Z38xx rack mounts

[Bruce Lane]

Something I've done for several projects is to seek help from these
nice folk:

http://www.frontpanelexpress.com/

A custom panel I did so I could rack-mount my Comcrap cable modem
(along with the rest of the network gear) ran about $75 or so.

What I would suggest doing with the Z38xx series is to simply do a rack
panel with an appropriate size cutout, then place holes for the mounting
screws and just bolt everything together.

Keep the peace(es).

[time-nuts] Small IRIG display wanted

[Bruce Lane]

Fellow time-techies,

I'm on the prowl for a small panel-mount IRIG-B display, similar to the
Datum 9520 series (they made one for aircraft use, which just happens to
be the one I'm after).

The only critical things about it are:

--Needs to be able to run directly off a 12 or 24VDC source.
--Maximum display width would be 7 inches. Height is not a big issue.

If you have something laying around which you think might work, please
contact me off-list.

Thanks much.

[time-nuts] Arbiter 1088B: Oncore receiver?

[Bruce Lane]

Fellow time-tickers,

I've recently become the owner of an Arbiter Systems 1088B GPSDO. It's 
a neat unit -- four programmable (by jumpers) outputs for a variety of signals 
-- but it's acting a bit strange.

Specifically: No reception of any satellites. I strongly suspect the 
receiver board, and it resembles a Motorola Oncore, but it's not like any 
Oncore I've ever seen (horizontal 10-pin header, no shield where a shield 
usually exists, etc.)

Does anyone else own one of these beasties, and can perhaps provide a 
bit of guidance?

Thanks much.

Fellow Time Trackers,

Does anyone happen to have an Odetics GPStar Plus (their model 565, if I

If so, could I bother you for some detailed photos of the innards,
particularly the main PC board jumpers, the additional power supply and
any extra cabling the rubidium module uses?

My goal is to retrofit my own GPStar.

Thanks much.

Hi, Arthur,

I just found an old post of yours from Feb-2012, where you detailed,
essentially, converting an FEI/Zyfer 365 to a 565.

I'm going to be in the same boat very soon, as I just got hold of a 365.
Could I trouble you for a dump-file of the EPROM you mentioned, as well
as any details you might have on doing the receiver adapter board?

Thanks much.

[time-nuts] Mike & Key Swap Meet

[Bruce Lane]

This is directed primarily at those in the Pacific Northwest region of 
the States.

The 31st Annual Mike & Key radio club electronics swap meet will take 
place this Saturday, March 10th, at the Puyallup Fairgrounds Pavilion 
Exhibition Hall, 110 9th Ave. SW, Puyallup, WA, from 09:00 to 15:00 local time.

This is a big event, typically drawing over 300 vendor tables, all 
crammed into 44,000 square feet on two floors.

SHAMELESS SELF-PROMOTION ALERT: I will be there, selling and buying, 
and among my other goodies up for grabs this year are a Unisite programmer with 
MSM, PinSite, PPI adapter, PLCC52 PPI socket adapter, and a UV EPROM eraser. 
I'll also have some nice Weller soldering stations, and a Pace 'Hot Tweezer' 
station for desoldering chip components.

For the hamateurs among us: Talk-in is on the club repeater, 146.820, 
negative offset, transmit PL only 103.5 (1A).

Keep the peace(es).

Re: [time-nuts] Schematic capture, anyone?

Good eve,

I must be the exception... I've tried Eagle, most recently about three 
months back. I can't stand it. I find it, for my purposes, to be about as

I've not yet tried DesignSpark, but it looks very promising.

Personally, I use an old version of OrCAD (9-dot-something, I think).

Happy tweaking.

Re: [time-nuts] US New Year countdown - accurate?

[Bruce Lane]

I'm beginning to think this is not an uncommon thing. One of the local 
TV stations (KING 5) does "New Year's at the Needle" every year, and they 
always have an on-screen countdown to midnight.

For as long as I've had GPS-referenced clocks, their count has been 
off. Sometimes fast, sometimes slow (this year, slow by about 12 seconds).

You'd think a network broadcast station could afford a simple GPS 
clock. Apparently not...

Happy ticking.

[time-nuts] Best way to...?

[Bruce Lane]

Hi, gang,

What's the best way folks have found to remove the Ebay special 5680's
from the hunk of PC board they're rivited to on arrival?

On a related note: Any speculation on whether an SMA connector could be
added to accommodate the 10MHz output? I seem to recall the 5680's have
an internal connector for such, and it just takes a jumper to bring it
out.

    Thanks much.

In terms of firmware files, it's pretty much a mirror of KO4BB's site. 
I don't run a content engine as he does, though. Just straight FTP.

I would be more likely to believe this if the setup had not been working
just fine for the last four years. ;-)

No, based on what I've read, I'm definitely inclined to believe it's a
1024-week rollover thing.

(still more...)

This idea fascinates me, as it is, potentially, the easiest to correct
AND the unit itself is vintage mid-90's. This would also explain why the
thing stayed working for a while after the last 1024-week roll.

I think I'll pull out the firmware, see if I can find the compile date
in a dump of the EPROM, change said date, and put the whole thing back
together. At worst, I'll end up with the same situation I have now. At
best, it'll fix it.

No matter what, I'll post the results. Dennis, thanks much! I hadn't
even considered that line of thinking.

[time-nuts] Epoch rollover?

[Bruce Lane]

Hi, gang,

Did we just have another GPS epoch rollover? My trusty old Odetics 425
seems to believe the date is March 4th, 1992.

I could probably correct it in firmware, if I looked hard and long
enough, but the ToD is still correct and the frequency standard is
staying nicely locked. Not sure if recovering the correct Julian date is
worth the effort.

Thanks much.

Re: [time-nuts] Spectracom 8182 Netclock/2

[Bruce Lane]

I went through something very similar when I reverse-engineered a 
module Data I/O used in their programmers for disk storage (the MSM, or Mass 
Storage Module).

The best way I've found to do it is make a drawing of the board itself, 
plus all its IC's and other components. Doesn't have to be anything fancy, just 
an outline plus little rectangles (suitably labeled, of course) for the 
components.

Next, identify your power and ground rails.

Finally, using a continuity tester (preferably something which beeps 
when it gets shorted), start with a pin on an IC you know is not the IC's Vcc 
or ground pin, and check for continuity to every other IC and component. 
Lather, rinse, repeat.

As you go, make a "netlist" of which IC pin connected to which 
component, or power or ground rail. Example:

U1-11 (means the IC labeled U1, pin 11): U2-6, U5-2, 10k pullup to +5

This means pin 11 on U1, pin 6 on U2, and pin 2 on U5 would all be 
connected together, and to a 10k pull-up resistor to the +5V rail.

Once you finish doing the entire board, you can sit down at your 
computer with your favorite schematic-drawing package and your netlist, and 
re-draw the circuit. Yes, it's time consuming, and takes lots of patience. It 
took me over a month to do the MSM, and that was a relatively simple board. 
However, in the end, you have a very usable schematic and a great idea of how 
the circuit elements interact. This is never a bad thing.

Happy tweaking.

Re: [time-nuts] HP quality

[Bruce Lane]

Six-sigma disease was all over the place, unfortunately. I spent seven 
years with Motorola, in their former Communications Sector, and it always felt 
like we spent more time on politics and "quality meetings" than we did actually 
doing what we were, supposedly, hired to do (fix things!)

Boeing was just as bad, if not worse. Spent six years there, mostly in 
computing support. Upper management got all excited about some bizarre book 
called "Who Moved My Cheese?" and something equally bizarre called "Tiger 
Teams."

I suppose it all meant something to the paper-pushers. To those of us 
on the tech/engineering side, it was worse than useless as it tended to 
distract from doing a good job.

As for "ISO 9001" or whatever -- Don't even get me started!

The only time I wear one is if I'm traveling, and I need to be certain

Half the band, anyway (220-222). And no, they never did make any use of

There are still quite a few repeaters and experimental modes being used

Re: [time-nuts] Lightsquared goes Global...

[Bruce Lane]

They already did, some time ago, at least for much of their engineering.
I spent six years with them (and I'm told I did good to last that long),
so I speak from (bitter) experience.

--They used to make much of their own avionics for flight controls and
instrumentation. No more. They sold off their entire electronics division
to British Aerospace back around 2000.

--They used to make their own PC boards. Nope. Got dumped around the
same time.

--Wing engineering and design has been done in Russia since around 1999,
at least.

There are probably stacks of other examples which I've either missed or
don't know about, but I will say this much: I think their ultimate plans
have always been to move the rest of manufacturing offshore. The NLRB
thing is merely one symptom of a much larger disease, one which started
(no surprise) just about the same time as McDonnell-Douglas bought Boeing
with Boeing's money.

I was laid off at the end of 2002, along with a stack of other folks.
Honestly, I have NO regrets.

I'll let it go at this since this is, obviously, off-topic for TimeNuts.

Happy clocking.

Re: [time-nuts] Lightsquared goes Global...

[Bruce Lane]

Seems to me such an issue only increases the chance of Lightsquared's
whacked-out ideas getting shot down in flames (as they should be).

May their marketer-driven hype rest in peace(es).

[time-nuts] One heck of a GOOD Ebay seller!

[Bruce Lane]

Fellow techies,

In light of all the horror stories on Ebay, I thought it would be a 
Good Thing to call attention to a GOOD seller for a change.

If you ever deal with seller ID "toomanyamps," do so with absolute 
confidence! I had bought from him what was advertised as 300 feet of siamese 
cable (cat5 plus a 16-gauge pair for power), but what arrived was 125 feet.

Within less than an hour of my notification, I found a terrific apology 
for the hassle, and my payment refunded IN FULL despite the fact I'd only asked 
for $25 back.

I am solidly impressed.

Happy dealing.

[time-nuts] Upgrade project, Odetics 325/425

[Bruce Lane]

Fellow clock-tickers,

Just a point of interest. I have successfully upgraded my Odetics 425 
by replacing its original quartz OCXO with an Efratom (Ball) FRS-C series 
rubidium oscillator.

The process was pretty simple: Wire the FRS-C in, with practically 
identical wiring to the OCXO, and (since the bottom of the case is already 
drilled and countersunk for an FRS-C) mount the thing. The only other steps 
were to flip switch #2 on the MPU board's pack to ON, and (as a purely cosmetic 
touch) to add a 'lock indicator' LED, driven by the FRS-C's 'Lock Indicator' 
line. 

Reassemble, power on, wait about fifteen minutes, and everything locked 
up and behaved beautifully. It was ticking happily along even as I left work 
this afternoon.

I see no reason why this trick should not work on any other Odetics 325 
or 425. If anyone needs more details, let me know.

Happy tweaking.

[time-nuts] Datum 9390 firmware?

[Bruce Lane]

Fellow clock-watchers,

I've become the proud owner of a Datum 9390-56110 GPS standard with a 
rubidium oscillator. I was informed, by the seller, that the unit's firmware 
kind of lost its collective mind when confronted with the GPS epoch rollover.

Would anyone happen to have a firmware update for this unit, or know 
the right route to take to find one? A manual would also be helpful.

Thanks much.

[time-nuts] Cs Tube Shipping

[Bruce Lane]

Given the discussion of air shipping for Cs tubes, I felt compelled to 
point out that Pelican cases, though a bit pricey for the bigger ones, make 
outstanding shipping and storage containers. Their 'pick-and-pluck' foam liners 
allow you to configure nearly any shape you might need to cushion the contents.

There are multiple vendors on Amazon who have pretty good deals on the 
things.

Happy timing.

Re: [time-nuts] Interesting "ware of the month". ..

[Bruce Lane]

After looking, and reading some of the other replies, I'm not so sure. 
That's an awful lot of DSPs and FPGAs for a timing receiver, and the silver 
square (Y1) in the upper left looks like an OCXO rather than a GPS receiver.

Neat site, though. I'm going to bookmark it and see what kind of 
bizarre hardware gets thrown up for the next "ID this thing" run.

Keep on tickin'...

I must not have made myself clear. I certainly plan to use the

Already a bit ahead of you, Don. The Mega just happened to be the one I

the Mega to construct a clock which runs from decoding NMEA sentences, and I'm 
using his source code to help me along.

That's the thing. I don't want to have to rely on PC hardware. I really 
want to make something which is stand-alone, and can be wired to a variety of 
displays.

Keep the peace(es).

Re: [time-nuts] IRIG-B with Arduino

[Bruce Lane]

In fact, I was looking very hard at the 328P. AND I just happen to have 
an STK500 on the way from the east coast (thanks to an Ebay purchase).

Already got AVR Studio installed, and I also have IAR's AVR package 
standing by. In short, I've got plenty to learn with.

And you're right. I'll be learning both C and AVR assembler as I go 
along, but the way I learn best is to actually DO something with programming 
rather than just taking abstract example problems.

Banzai! ;-)

[time-nuts] IRIG-B with Arduino

[Bruce Lane]

Fellow clock-tickers,

I'm finally starting to learn microcontrollers, and have selected 
Atmel's AVR line as my tool of choice. I've also discovered the Arduino site, 
and am starting to learn their IDE as well.

My first goal will be an open-source/open-hardware IRIG-B decoder 
(takes IRIG-B 1kHz stream, sends the timecode to an LCD panel). I've noticed a 
distinct lack of hobby-priced decoders on the market, and I intend to try and 
remedy that.

My initial development platform will be the Arduino Mega-2560 board. 
However, that particular microcontroller is unlikely to be my final chip of 
choice due to the fact it's not available in a hobbyist-friendly DIP package. 
If others with more development skill have suggestions for a different chip, I 
will gladly listen.

Stay tuned for further developments (no pun intended). I expect this to 
take at least a few months, as the learning curve looks kind of steep.

[time-nuts] Lucked out

[Bruce Lane]

Fellow time-tickers,

I lucked out on that NTS100i. No, it didn't have GPS (it was the IRIG
version), but the fix was very simple.

To recap: The Ebay seller had said he was unable to get it to
synchronize to an "IRIG input" no matter how hard he tried.

The solution: Turns out the IRIG version of the 100i (sub-model NIC-215)
has a hardware jumper setting for different IRIG code formats. I
discovered this when, on a whim, I fed the thing an IRIG-E stream -- and
it locked!

Some further experimentation located the jumper. I fed the thing a
standard IRIG-B signal, then moved the jumper to different positions
until I got a lock.

One quick set of modified rack brackets later, the thing is doing its
duty as a slave clock and NTP server, drawing its reference from my
Odetics 425.

I would call this $47 well-spent. ;-)

Re: [time-nuts] NTS-100 scored

[Bruce Lane]

Not me, no. However, still, no big... It'll be interesting to see what 
I can do with it once it gets here.

Another thing that occurs to me is it may have been field upgraded by a 
previous owner. I just won't know for a week or two.

Thanks much.

Re: [time-nuts] NTS-100 scored

In this case, I found out a little more. It actually is an NTS-100i,
sub-model NIC-215.

I have no idea if this will eventually be good, bad, or indifferent, but
the price was right.

Thanks.

[time-nuts] NTS-100 scored

[Bruce Lane]

My scrounging luck pulsed this morning, netting me a cheap ($47 with
shipping) TrueTime NTS-100 from That Auction Site.

It was billed as a 'tech special,' in that the seller claimed it powered
up but he was unable to "get it to lock to an IRIG signal."

Unless I'm mistaken, the NTS-100 is a GPS-based device, yes?

I'm off to hunt for its manual, but if anyone has any words of wisdom

[time-nuts] Datum 9200-209 Display

[Bruce Lane]

Fellow time-benders,

Does anyone happen to have the tech manual for the old Datum 9200-209
reader/display? It's currently set to decode IRIG-E at 100Hz, and I need
to reconfigure it (if possible) for IRIG-B at 1kHz.

Thanks.

Re: [time-nuts] XL-AK Receiver: Worth it?

[Bruce Lane]

The manual I found at Symmetricom's site says the 10MHz out is an
option, not standard equipment. As to why I'm asking this, it's because
I've never encountered an XL-AK before and I'm separated from the actual
unit by about 3,000 miles.

A photo I've been sent of the back panel shows only IRIG-B out, antenna
in, and 1PPS out. There are plugged-up holes for other connectors.

Thanks.

[time-nuts] XL-AK Receiver: Worth it?

[Bruce Lane]

Fellow time-tickers,

I'm considering the purchase of a surplus TrueTime XL-AK series GPS
clock. As near as I can tell, it does not have the frequency output
option for 10MHz.

My question: How easy (or not) is it to add this option? Are the
necessary components already present in the unit, just needing some
creative jumpering to bring to life, or was there a separate module?

Also, as a point of curiosity: What's the GPS receiver in the XL-AK, and
what format is it putting out to the receiver's microprocessor? (NMEA?
Binary? Something bizarre?)

Thanks much.

[time-nuts] BFT Web & FTP going down for systems upgrade

[Bruce Lane]

Just a heads-up: As of 19:30 PST, 17-Jan-10, Blue Feather's FTP and web 
systems will be going down for system upgrade. I don't anticipate being off the 
air for more than a couple of hours, tops. The FTP library itself is in no 
danger because the server merely acts as a front-end to another server which 
holds the actual library. That way, nothing I do to the front end causes data 
loss.

I'll post another note when we're back up.

Keep the peace(es).

[time-nuts] Odetics 425 getting truly flaky...

[Bruce Lane]

Fellow time-techs,

Nothing lasts forever, and my faithful Odetics 425 is doing its best to
demonstrate that fact. Before I put "Fix or Replace the thing" on my
project list for the new year, I thought I'd check to see if any other
owners of the beasties have run into the symptoms I'm getting.

Specifically: The unit will go from TIME LOCKED and TFOM=4 to TIME
COASTING and TFOM=5, pretty much at random.

What I've done: Reseat every IC the thing has, replaced a couple of
interconnect cable DIP sockets with hi-rel machine-pin style (they were
cheapie single-leaf before), and done a manual recalibration of the
oscillator.

I know for a fact that the single-leaf IC sockets are a huge source of
problems in older gear. My next step would be, I'm thinking, to replace
every single IC socket with a high-rel part (that's a LOT of
desoldering!)

So -- Any thoughts before I start ordering new chip sockets? ;-)

Thanks.

[time-nuts] DIY Goodness

[Bruce Lane]

Fellow clock-tickers,

I just turned one of my spare TCG/Translator units into a nice GPS
clock.

How did I do this, you may well ask? Well, honestly, I cheated a bit.
When I was cleaning up in the garage earlier this month, I came across an
item I'd bought for cheap last summer from Outback Technologies.
Specifically, a W. Clark and Associates (now Masterclock) GPS-200 time
code generator. It's a small board (about 4" by 6"), and its sole purpose
in life is to listen to the GPS birds and spit out either SMPTE or
modulated IRIG-B time code depending on how you set its DIP switch pack.

My spare TCG was an old TrueTime 900, purchased from Boeing Surplus
about 4 years ago. Once I pulled the GPS-200 out of its aluminum box, and
desoldered a couple of protruding parts (mainly the D-sub 9 connector and
status LED), the whole board fit nicely into the 900's enclosure (with
the aid of a bit of Velcro tape).

There were more than enough spare holes on the back to, with a bit of
drilling out, support the antenna connector, a panel-mount LED to replace
the board-mounted one, and a switch to select either the GPS or the
external connector for a code source.

Mount the receiver board, give it 5V from the 900's internal supply, and
wire its output to my switch. Vyola! GPS-locked clock/IRIG generator.

I consider it to have been a very productive use of my time(code). ;-)

    Happy tweaking.

Technically, a ROM image is made by creating an Absolute Binary (Data
I/O #16) format file of the device being read. However, formats such as
you describe were, if I recall correctly, compatible with being read from
a text file as long as the programmer being used to make a new device
supports the format in question.

I have other Data I/O programmers here which are quite capable of
producing a binary image file. If you would like to send a chip to me for
comparison against the source file you're curious about, I should be able
to deal with it and return said chip when finished.

Happy tweaking.

Re: [time-nuts] Home NTP ? & GPS Clock s/w

[Bruce Lane]

There's a windows package called NMEATime which is fairly cheap. It 
will accept input via serial port from just about any GPS receiver which speaks 
standard NMEA sentences, and it will use that to sync up the PC's clock. It 
will also act as an NTP time server, and it'll even generate a modulated IRIG-B 
signal using the system's sound card.

http://www.visualgps.net/NMEATime/

Happy timing.

Re: [time-nuts] GPS-based frequency reference in "Everyday Practical Electronics"

[Bruce Lane]

Good catch, thanks! I just ordered both back issues. That'll give me 
something to do with the 15L module I have stashed in my bench drawer.

One question: I placed the order, and completed the checkout process, 
but have not yet been able to download the issues. As near as I can tell, the 
publishers actually E-mail you a download link once they finish processing on 
their end, yes? If that's the case, I'm guessing I won't see the download code 
until, say, Monday?

Happy timing.

Re: [time-nuts] Datachron, Inc.

[Bruce Lane]

There were two popular ways to transmit IRIG time code: DC (TTL) level 
and AM on a 1kHz audio carrier. Your display might be jumpered for DC level 
code.

Open it up, look around the input connector. I'll bet there's an 
internal switch or jumper to select DC or audio carrier.

Happy tweaking.

If you can, I would also appreciate a copy of the image files so I can
archive them for others who may be in need. E-mail attachment, in the
form of a ZIP or similar archive, would be fine.

Re: [time-nuts] Off Topic question...

[Bruce Lane]

For Canada? Nothing at all. My wife and I are frequent visitors to the 
BC area, thanks to the fact our falconry mentor lives on Vancouver Island. In 
four-plus years of frequent border crossings, including one where we were 
delivering a Harris hawk, not once were we ever asked about innoculations or 
informed that anyone from the States needs such.

Happy travels.

Re: [time-nuts] Looking for recommendation GPS time/freq standard

[Bruce Lane]

FWIW - The Z3801 and 3816 are nearly identical.

Personally, I've been very pleased with my Z3801. It has been a real 
workhorse, serving reliably for the last 5-6 years without a hitch. I use it as 
an external reference for my service monitor (IFR/Aeroflex 1600A/S), and I've 
yet to see a 'bad' measurement as a result.

I can't speak to phase noise from the thing, since I've never bothered 
to measure it, but consider where the Z-series was used: Cellphone sites. This 
means that any phase noise would likely become a nasty problem in terms of 
signal quality at the cellphone end, and that HP would likely have gone to 
great lengths to minimize it.

Happy tweaking.

[time-nuts] Odetics 325/425 owners, rejoice!

[Bruce Lane]

Fellow clock-tickers,

Thanks to the generous assistance of a customer service rep at Magellan 
Navigation, I have received a full .PDF manual covering the Magellan OEM5000 
receiver module used in many of the Odetics SatSync 325 and 425 GPS clock units.

This manual contains full details on both ASCII and Magellan Binary 
outputs from the receiver, including that previously-elusive PMGLK sentence 
that was driving me nuts.

The information in that manual, combined with a bit of hardware 
ingenuity in the microcontroller world and the Odetics equipment manual, should 
be enough to produce a hardware translation device which will (hopefully) allow 
the use of a standard (and much more readily available) NMEA-output receiver 
module. That's going to be a long-term project for me in the coming year.

Anyone who wants to try and beat me to it is, of course, welcome. ;-)

The manual may be found on the Blue Feather FTP archive.

ftp.bluefeathertech.com

Sign in as user ftp and the password can be anything you want (though I 
prefer an E-mail for logging purposes).

The path is /electronics/radio/GPS/receivers/OEM/Magellan/oem5000

The file name is OEM5K.pdf

Happy reading.

Re: [time-nuts] I'm back! And I need a receiver...

[Bruce Lane]

Hi, Bill,

Thanks for the offer, but I also have a goodly number of the Datum 
9300's and similar units.

What I really need at the moment is at least a partial "turnkey" 
solution. Ideally, I want to fix the Odetics clock as it has been very reliable 
outside of the GPS receiver.

I know if I look long enough, I'll find something.

[time-nuts] I'm back! And I need a receiver...

[Bruce Lane]

Fellow clock-tickers,

I have returned from a most worthwhile Mexico vacation! It was great 
fun, but I'm glad to be home.

With that said - Murphy struck, hard, the day before I left by taking 
out the GPS receiver (again!) in my Odetics 425 clock. I'm beginning to wonder 
if this was a common failure for these units.

In any case -- Does anyone have a spare Magellan model OEM 5000 module 
that I could convince you to part with?

Failing that -- I'm not optimistic about being able to modify the 
Odetics to work from a more modern NMEA-output module, so it is likely that I 
would have to replace it. What I'd be looking for is a rackmounted unit, no 
more than 4U high, that can put out disciplined 10MHz and IRIG-B time code. A 
Trak Systems 882x series would be nice, but I know how popular those are.

Thanks much.
