Re: [time-nuts] Anybody want a Thunderbolt power supply?

2016-09-01 Thread Stan, W1LE

Jim,

I use a HP 6236B triple power supply to drive 2 each T'Bolts. Works fine 
after the T'Bolts warm up, with limitations on a cold start up.


But once they warm up all is OK.

Using a common outside puck antenna and a HP RF distribution block I can 
run 3 T'Bolts and get essentially the same results.


#1 T'Bolt is on a HP 6235A DC PS and #2 and #3 are on the 6236B. #1 has 
been on for years.


I am planning to box up and use a  Mean Well SMPS common power supply 
that will handle the load current of 3 T'Bolts starting cold.


Adding a few digital panel meters to measure individual load currents 
and voltages.

Re: [time-nuts] 53132A Cooling fan

2015-01-11 Thread stan, W1LE

Hello The Net:

Mike, thanks for the 53132A fan info.

I also have a noisy fan. I have considered adding a proportional fan 
controller since more colling is needed
if aditional options are added, like a more stable internal reference or 
a prescalar to 3 GHz or 12 GHz.
Less cooling is needed if no internal options are included. Less cooling 
can mean a slower fan speed and lower acoustic noise.


Anyone have any thoughts on exactly where to put a temperature sensor 
for a proportional fan controller?

The W1GHZ.ORG website had a fan controller.

Anyone have any thoughts on how to increase the intensity of the dim 
display ?   Is it a power supply issue ?


I use my 53132A with TimeLab to measure the performance of different 
oscillators.

My FS700 arrived yesterday, complete with bonus artistic  effects due to
the sender believing a thin coat of bubble wrap  with an outer layer of
cardboard cut from a box and just taped on top,  no padding or air gap, would be

Physically at least it seems to have survived remarkably well, no damage to

  the BNCs and the front panel trim, outer covers and transformer cover all
looking pretty good again after a couple of hours work.
Not having any rack ears attached was probably quite a bonus with it
shipped like this!
The only obvious internal damage, and it might have been that way before
shipping anway, are three vertical inductors held to the circuit board by
silicon rubber or hot melt adhesive that are loose but still seem to be
electrically connected
  
Anyway, it powered up ok and is indicating it's locked onto Anthorn in the

Lessay chain, even if it does believe it's found the never built station at
Loop  Head in Ireland:-), but I'm not sure if it's functioning properly.
  
It's close enough that I don't want to start pulling it apart for the sake

of it without being sure, and it may just be a case of waiting for it to
settle,  but after showing as locked for several hours the 10MHz output, as
indicated  both by the internal display and an external counter, is swinging
back and  forth quite rapidly anywhere within approx +/- 3 parts in  10^9.
There was an obvious change in the crystal oscillator frequency as the oven
  warmed, and another when the conditioning seemed to take over, but it's
been  hunting like this ever since it first indicated lock and with no
obvious  change, just when I do think it might be converging it opens up  
again.
  
So first question is, can anyone tell me please if this is normal or

close enough that I should expect it to settle eventually, or do I need to
start  investigating further?
  
Second question, could somebody confirm please whether or not the LCD

display is supposed to be backlit?
This one isn't, but it's not immediately obvious from photos I've found
online whether or not it should be, and although the contrast range on  this
seems to be fine it's certainly not easy to see.
  
Last question, for now at least:-), this unit has the FS800 PCB rev C, with

  revision 2.0 firmware, does anyone know if any later firmware is available
that  includes Anthorn, or at least Rugby, as part of the Lessay chain?

[time-nuts] New Acquisition: HP-53132A

2014-02-01 Thread stan, W1LE

Hello The Net,

I just got in the counter and the fan is always ON, even with the front 
panel switch OFF.


I looked in the manual but could not find anyway to change this.
The counter has the standard internal 10 MHz reference, but I will be 
using a Trimble T'bolt GPS/DO for the external reference.


The fan is part of the power supply module. I can see a possible need 
for it if a premium ovenized reference is always ON.

But I do not have the premium internal reference.

Is there a way to only allow the fan to be ON, if the front panel switch 
is ON ?  Possibly a jumper setting ?


Are there any key strokes to determine the software version, other than 
a check sum ?
I do not have the standard HP serial number, with the vintage 
(manufacturing date code) code first.

The unit was manufactured in Korea.

PFC to me is power factor correction, not only the classical power

 but also to remove the harmonic load  current imposd on the electrical 
power system.
A '90's onward technique. in th 80's and 90's without the harmonic load 
current reduction and having
 a few 100 end items of equipment, each withtheir own  a switch mode

 it was not uncommon to find hundreds of amps of the third harmonc on

And ripple current can be a major source of power-line frequency noise in
all electronics.

The main reason why switchmode power-supplies today (can) outperform linear
power supplies with respect to noise, is because the legally mandated PFC
correction eliminates the bridge-rectifier ripple harmonics.

I would not hessitate to use a good quality switchmode to replace the linear
supply in a HP5370B.

I did some experiments a couple of years ago, with an audio-amplifier:
I put a standard PFC corrector chip on the secondary side of the trafo.

The overall result was not satisfactory, but the 50 Hz sneer
we all know and hate was absent, and the Tzoing! power-on mechanical
shock from the trafo was also eliminated, as was the consequent dimming of
the lights ;-)

The main reason not to do this, is that you need some physically gargantuan
coils for a 10A+ PFC-switcher.

Re: [time-nuts] FLUKE PM6680B Counter Time View software for the PC

2013-05-25 Thread Stan, W1LE

Hello A.B.,

 Actually TimeLab is collecting data right now and I am quite happy 
with it.


I will be even happier when the PM6680B arrives on Tuesday and TimeLab
can drive it directly without the talk only function I am currently using.

The FLUKE TimeView is only an alternative, whose capabilities I hope to 
experience.


I am currently using a HP5384A in talk only mode (HPIB address 31) with 
TimeLab to look at some OCXOs.

A T'Bolt GPS/DO provides the 10 MHz reference.

Now I better understand why there is a rubber gasket under the adjustment
screw cover on the hermetically sealed cans of the OCXO.
I can see the barometric pressure changes on frequency using TimeLab, at 
E-10 levels.


Maybe the supposed drift due to the atmospheric pressure is due to the 
propagation

of the GPS signals that can effect the 10MHz reference ??
May have to go back to a Rb reference to verify.

It is also interesting to see how aging drift improves with time under 
power.


I had been holding out for a HP 53132A counter but I am a frugal Yankee and
I settled on the PM6680B for about 25% of the cost of a HP 53132A.

The oscillator will lock to an external 10 MHz source, but then one
needs to buy both a 10 MHz rubidium as well as this 40 MHz TCXO. Hence
I was wondering if there was a cheaper more compact solution, which
just used a rubidium, and dispensed with a TCXO.

needs to buy both a 10 MHz rubidium as well as this 40 MHz TCXO. Hence
I was wondering if there was a cheaper more compact solution, which
just used a rubidium, and dispensed with a TCXO.

Re: [time-nuts] GPIB counter logging / plotting software?

Yes, there is software out there. Others would best comment.

My indirect approach is different.

I take the unknown RF signal into my RX converter with a GPS/DO 
stabilized LO,
then the IF into a RX with a stable LO, and take the audio out to a 
computer soundcard and use ARGO software

to display the drift. ARGO can be found at:

Re: [time-nuts] Locked onto LORAN 8970 GRI Monday AM

2013-02-05 Thread Stan, W1LE

Hello Bill,

I have no real idea. I can not DF at this time. Antenna is an omni.

I suspect the FS700 receiver looks at GRI data and placement within the 
waveform
and goes to a look up table in firmware to tell me the supposed location 
to the LORAN plan 10 years ago.


Only thing that may be possible is the RX signal strengths are different 
for master and slave,
so they may be physically separated or their TX RF is from one location 
at different power levels.


It will be interesting what your contact at Wildwood (NJ) has to say.

Hello Chris,

You are on the right track.

I have had the Trimble Thunderbolts (3 each) for about 5 years now.
Just to be sure everything compares favorably
I use Lady Heather PC software to monitor their performance (de KE5FX 
website)


Stay tuned to this reflector, lotsa interesting discussions.

For me, it all started when I needed better than 1 Hz accuracy to  monitor
the 137 KHz band for local experimental activity.

the 10 MHz from the GPS/DO was the external reference to the HP-3336B 
synthesizer
as a RF test signal to calibrate my RX (IC-706MK2 and a IC-703+) and PC 
soundcard.
Spectrum Lab PC software has a provision to calibrate the PC soundcard, 
for greater accuracy,

but you have to have a very accurate signal source.

Then there are the FMT-Nuts, frequency measuring contest nuts, who are 
getting better than 1 milliHz
frequency measurement accuracies on intercontinental (US) HF 
communications !!


I was also doing LORAN-C receiving and could achieve Cesium accuracy,
at least 2 orders of magnitude greater accuracy than a GPS/DO.
But US/Canadian  based LORAN went off the air, but it is still available 
in Europe.

I do not know where you are located, so maybe LORAN has potential for you.

AUSTRON made a variety of LORAN-C receivers, 2100F, 2100(R), 2000, etc
Stanford Research Systems (SRS) also made the FS-700
Because they are useless in the US, pricing on Ebay has dropped.

The classical approach:

Look at the spectrum and notch or filter out what is not wanted.

The FS-700 does have a set of filters and a front panel LORAN output

to monitor with a spectrum analyzer for filter settings.

I like the AUSTRON model 2048 LF Multifilter, just like a 1X4 RF

[time-nuts] LORAN-C

2012-05-01 Thread Stan, W1LE

Hello The Net:

LORAN signals are still being received at a 89700 microsecond GRI.
I concur with others that there is only one station transmitting the 
master(M) and the slave(X) signals.

My SRS FS-700 Rx shows equal received signal strength for both signals.
Reports indicate the transmitter is at the old Coast Guard LORAN 
engineering site at Wildwood NJ.


Since I turned the equipment on last Sunday night, I have had continuous 
lock on the

FS-700, Austron 2100, and a 2100F.

Compared to the GPS/DO 10 MHz from the T'Bolt, I am getting accuracies 
to the mid -13s,

as indicated on the FS-700 phase meter.

Next step is to lock up the signal on an oscope, triggered by an 
accurate 11.148272 KHz signal

( reciprocal of 89700microsec).
That way I should be able to see the pulses and the E-LORAN experimentation.

My set up at home uses a 40' high delta loop antenna, 2 orthogonal loops 
terminated on the top with a
600 ohm resistor, a ARR preamplifier with battery at the antenna , a RG6 
coax run to the shack,

Astron 2084 multicoupler, then the receivers.

You need a really amazing stable and noise-free trigger to lock
onto a 5.5Hz (see below) sine at the required level of stability
(~2usec).

I used my HP33120A once, but its square output is made with a
comparator on the sine wave, and has pretty bad jitter.
Switching to saw-tooth solved that, defining my own arbitrary
square-wave was even better, not sure why.

You want 1/(2*.089700) = 5.574136 Hz, otherwise every other
loran-c pulse will cancel out due to the A/B coding polarity.

If you don't have a counter-based signal generator, consider stealing
a GRI or FRI-rate signal from one of your loran-C receivers, I belive
the AUSTRON 2000/2100 offers it on a BNC at the backside.

But the Austron 2100 and 2100F had to be manually reset to acquire again,

How did you determine there was a short lived other station in the chain ?
Other than manually going to the screen that shows the additional activity ?

[time-nuts] Wednesday AM Update: LORAN-C Reception on Cape Cod

2012-03-21 Thread Stan, W1LE


Don, you are absolutely correct, Dana is in Indiana and not Illinois.

Austron offered a model 2084 LF Multicoupler, with 1 antenna input and 4 
outputs.
Could be AC or DC powered, with peak and spherics indicator lamps, and 8 
each tunable
notch filters from 70 thru 130 KHz that can be individually switched 
inline or out.


I should be able to take the FS700 Loran-C (RF) front panel output, feed 
the multicoupler,

then feed a Austron 2100F and the 2100 to monitor other GRIs.
Just have to find my notes on how to set up the older RXs.

I had lock onto 89700 microsecond GRI overnight and using the internal 
FS700 phase meter
I got as low as 3E-13 for delta frequency between the Loran-C and the 
T'Bolt GPS/DO.

I am locked onto the Seneca, NY station.

Stan, W1LECape Cod   FN41sr


If I am not mistaken Dana is not in Illinois it is in Indiana.

Stations found: (ident: Amp in dB)
M59*   X56

Time since lock:   0:21:40  ( had lock overnight, but with an error so I 
did a new search)

Length last unlock:  0:10:42

Signal status:  a r b n o

I am using the standard SRS active whip antenna about 7' above ground in 
the back yard.

Receiver firmware is 1.19

As time permits I will compare the Loran-C to the T'Bolt GPS/DO, with 
the Tracor 527E.


It is nice to have Loran-C signal to play with.

I have not listened to these GRIs.

I hope to configure to use the single antenna with multiple Loran-C

Have to ponder that action Difficulty is that one receiver has to be

Longer chassis than the HP.

The PM6685 comes in a Rb version for internal reference.

for Rx and Tx (?).

This the label on the box :

http://dl.dropbox.com/u/15089947/NavSymm2.jpg

And these are the upper and lower sides of the unit :

http://dl.dropbox.com/u/15089947/NavSymm3.jpg
http://dl.dropbox.com/u/15089947/NavSymm1.jpg

Does anybody perhaps have a bit more information on this
GPS receiver, and possibly suggest a practical use ?
For example, would it be feasible to open the unit and recover
maybe the 1pps signal, and some sort of data strings ?

Re: [time-nuts] Cambrideg Thermionics Freq Measurements...

2011-10-15 Thread Stan, W1LE

Hello The Net:

The frequency measurement division broke off, but was still in Cambridge 
in ~2007.


I got a call from them about a 19 KHz pilot tone generator that was off 
freq at a
FM/NCE station on Cape Cod. After replacing the Optimod ($100) xtal, all 
was fine.


I will eventually think of that organizations name, but for now the POC 
was Richard.
Yes, his techniques were cryptic, but I doubt if his techniques exceeded 
the capability of any time

or freq nut's capability.

I would start with a search at SBE for such freq measurement organizations.

They also made a bunch of other electronic hardware like coil forms.
Again, very good quality.

The other thing they made was thermoelectric heat pumps and products using

At some point (70s? 80s? 90s?) they moved someplace else and changed their

I do sort of remember Cambridge Thermionics.  I came across their

Re: [time-nuts] Active LORAN antenna

2011-08-31 Thread Stan, W1LE

Hello Ulrich,

There are 13 each, double pages of schematics for the FS700.
Most of my pages are marked up. When I got the manual, before I had the 
hardware,
I read it thru and I highlighted each adjustment in the circuit to get a 
better understanding.

Not much of a plot, but a pretty good story.

If you need a specific page, I can scan each 1/2 page and you can paste 
together on receipt.
All I have is a simple A size Cannon scanner, but I can scan to high 
resolution.


The other alternative is to get a new manual from Stanford Research 
Systems for ~ 35$

Shipping may be a killer.

Please advise.

Re: [time-nuts] Active LORAN antenna

2011-08-26 Thread Stan, W1LE

Hello UL,

My SRS active antenna is internally potted in resin, so tracing the 
circuit is difficult.


I was able to chip away the PVC white housing and some of the black potting
material to get at the antenna input terminal. Then I repackaged it with 
a new CB antenna.
Living on Cape Cod, quite near to the former Nantucket Loran station, I 
can only rarely receive

some of the European stations.

The schematic in the manual shows a switch or a jumper for the gain 
reduction.
So, the schematic is probably an old version, and all bets are off as 
to what

the production models, we have, consist of.

I did buy the manual form SRS and the active antenna schematic shows a 
2N5951,
not the 2N5991 you mention. My schematic is a rev B, Document Number 
FS700-14

This document in not dated.

The frequency selective L-C filter network is different, see attachment.

If the attachment does not get thru, please send your direct e-mail address.

Gentlemen,

my friend Frank and I both miss the matching actice antenna for our
Standford Research FS700 Loran frequency standards. We also do not have a
schematic of it. Nevertheless we have tried to re-engineer the circut from
the part's list and the circuit description in the FS700 manual. Our result
is shown in the accompanying schematic.pdf.

The generator in the left in conjunction with the 10 k resistor represents
the expected high footpoint impedance of the very short (3 m) antenna. The
VDD in the right in conjunction with the 100 ohms resistor represents what
it believed to be inside the FS700.

Not shown here is a 100 k resistor that may be included between the filter
output and the 7 k resistor to form a 30 dB divider together with it. Also
not shown is a 390 micro henry inductance which's impact is not to be found
in the circuit descripion. Also not shown is a small neon bulb for
overvoltage protection.

The ac analysis shows that the overall filter function is well around 100
kHz. But it seems as if the fet (a 2N5991 in the original) would not have
enough gain to counteract the overall damping included in the front end let
alone to deliver some additional gain for the receiver's front end.

We both feed the receiver currently with dipoles for 80 m ham radio and a
resistor that makes the receiver think the active antenna is connected. The
receiver has a possible total of 130 dB gain and my receiver says it uses 94
dB gain while Franks receiver says it uses 102 dB gain. The noise margin is
also a bit better on my location. However, if one looks at the manual f.e.
at page 17 one could get the impression as if a receiver gain of 75 dB may
be considered much more normal as our values. Instead of improving the
reception everything gets even worse if the active antenna is connected. I
should also note that my qth is only 200 km away from SYLT (our German Loran
station) while Frank is even 70 km nearer to it.

Questions:

1) Anyone an idea what we are possibly doing wrong?

2) Anyone an idea for the 390 micro henry inductor?

3) Anyone own the original schematic?

Re: [time-nuts] Another mystery Wenzel OCXO

2011-05-28 Thread Stan, W1LE

Dan,

 I have been watching these for awhile, for a potential propagation 
beacon on 6M.

My project has not reached critical mass yet.

Some speculation:

The +12VDC DC power connection and GND are the input power for the 
oscillator and the oven.

One coaxial connector is the output at RF,  50 MHz.
One coaxial connector is the input VCO tuning voltage  ~ 5 VDC, (either 
+/- 5VDC or 0 to + 5 VDC).

The other coaxial connector may be for a oven monitor output signal,
either a analog signal for oven temp or oven ON/OFF status.
But I have no idea which female SMA does what.

If you find out the details, please advise us all.

Re: [time-nuts] smallest rubidium

2011-05-23 Thread Stan, W1LE

I also top post...

Consider the Symmetricom model X72 Rb. I can fit 2 each in my shirt pocket.
Some variants are programmable and spec'd for 12 VDC operation.

I did have problems with one unit that had microphonics when used
with a DEMI/N5AC microwave LO synthesizer in a DEMI 10 GHz transverter.

For a 20 MHz reference used in a HF transceiver I would consider a ISO 
Temp TC/VCXO at 10 MHz
and double it with suitable filtering. Provide a pot to easily net it 
as well

as a additional 10/20 MHz output to feed the counter.
The ISOTemps have been going for 30-50$, so it is a cost effective 
solution and

it may be stable enough for any HF operation. If used with a transverter,
you will still have to fight that LO drift. Unless it is synchronized 
with the 10/20 MHz reference.

What worked for me was to disable (postpone actually) the Windows PnP 
device enumerator for a serial device. It works for hardware serial 
ports as well as the USBtoRS232 converters.
This can be done with a registry patch which adds the 
Skipenumerations registry entry. Setting this to a big value skips 
the possible detection of any device (such as a serial mouse) on a COM 
port.
Search the net for details. E.g. here : 
http://support.microsoft.com/default.aspx?scid=kb;en-us;283063


Lots of the USBtoRS232 converters do not contain EEPROM to store a 
unique serial number. Without it Windows cannot be sure you unplugged 
the same device as you re-plugged in another USB port. Its behaviour 
is to assign it a new COM port number. Re-plugging the converter in 
the original USB port should bring back the same COM port number.
You will need to patch the registry again if a new COM port number is 
assigned. If you want to avoid this, look for USBtoRS232 converters 
that have the option to program a USB serial number (like the FTDI 
FT232R based ones)

I can move the COM port assignment for the adapter, but I can not find 
what COM port the mouse is using.

The mouse does use IRQ 12.

USBView software does show which USB ports are used, but not the mouse 
COM port assignment.


How do I fix (permanently assign) the Com port used for the mouse, so 
there is no conflict  ?

if your adapter uses one of the popular FT232 chips from FTDI, then your

Stan;
I had the same problem. The correct fix (i.e. permanent) is to buy a
RS232C plug-in board for your PC. This allows the port choice to remain
fixed. With the USB to serial adapter the port can change every time you
reboot the computer. I purchased a board with 8 db9 connector 'dongles',
this allowed me to have unique port IDs for all the RS232C devices that I
have afixed to the computer.

Hello Ed,   Thanks for the definitive Microsoft reference.

with the computer setting the USB port to COM10.
System worked fine with Lady Heather on the original computer.

I tried using the mod to theboot.ini file.I added:

NoSerialMice:COM10   on the very first line.

To date I still have a conflict with the mouse

I can move the COM port assignment for the adapter, but I can not 
find what COM port the mouse is using.

The mouse does use IRQ 12.

USBView software does show which USB ports are used, but not the 
mouse COM port assignment.


How do I fix (permanently assign) the Com port used for the mouse, so 
there is no conflict  ?

[time-nuts] Resolved: USB and Mouse conflict persists

2011-05-11 Thread Stan, W1LE

Hello The Net:

Thanks for all of the timely pointers.  The problem with XP Pro has been 
resolved.


My serial to USB adapter uses the Prolific chip. As indicated under 
device manager.

After plugging in the T'bolt to the adapter and into a computer USB port,
Device manager, under mice and other pointing devices showed an active 
Microsoft serial ballpoint

As suggested I left clicked and DISABLED it vs. deinstalling it.
Control over the mouse cursor returned to normal operation.

Adding a external USB hub by itself, had no adverse effects.
Adding a T'Bolt and adapter to the external hub had no adverse effects
adding a second T'Bolt did have a problem. but the ballpoint device was 
then DISABLED.

Adding a third T'Bolt to the external hub had no adverse effects.
Adding a cheapie Bluetooth USB adapter had no adverse effects.
Adding and pairing a Bluetooth mouse and keyboard had no adverse effects.
Under device manager, USB ports, advanced, I changed the COM port 
assignment to COM10, 11, and 12.
Lady Heather beta started up fine with their command line COM port 
assignments.


The motherboard is an Intel D945GCLF2D with installed dual core Atom 
processor. (~80$) MicroATX.
Total power draw is ~40 watts. Could be lowered a few watts even more, 
with a solid state hardrive.
I only have 1 each PCI expansion slot and that is occupied by the 
M-Audio 4 channel 196 K sampled soundcard.
Not the fastest CPU, but fast enough. and I have a DC power supply for 
it, to run off of +12VDC.


I will go back into the boot.ini and delete the NoSerialMice entries.
I will explore the /fastdetect:COMx command as well as the impact of not
allowing plug and play accessories from the BIOS.
That was last weekends project.

Next project is to get the Agilent IO/drivers and their ARB waveform 
software working
under serial control with a 33120A, option 001, that will use the 
T'Bolts 10 MHz as a reference.


Thanks for all of the timely assistance.
The pointers I got were a giant step ahead of what google found.

[time-nuts] OysterQuartz Saga: Final Report

2011-03-12 Thread Stan, W1LE

Hello The Net:

My OysterQuartz has been resurrected and I am happy with the results.

I appreciate everyone's response.

I researched local watch repair facilities and found one in town.
After finding the right person to talk to, who knew that the 
OysterQuartz really took a battery,

I had him send it off to the expert in Boston for a battery replacement.

Thanks for the pointers to the professional tooling to remove the back.

After 2 weeks the watch came back, working quite well.
The fee was 50$, mostly due to the effort to disassemble and reassemble 
the case.


I had never considered it a bling, but I will agree, a bling it is.
It was my personal entry into Time Nuttiness, decades ago.
Watch manufacturer spec was +/- 30 seconds in a year.

My original use was as a transfer standard from a AN/GSQ-53 (?)
LF timing system that used a UK broadcast.

A decent site for the history can be found at:

http://oysterquartz.net/

The shop manual was interesting, identifying the battery part number as 
well as where the adjustments are.


Interesting that the OysterQuartz is obsolete and has been out of 
production for 10+ years.


The rumors of a new design OysterQuartz with a 10 year battery life were 
quite interesting.


Thanks for all of the pointers and comments,

Stan, W1LE  Cape CodFN41sr

[time-nuts] Tool Needed to Access my Timer Battery

2011-02-15 Thread Stan, W1LE

Hello The Net:

When I retired almost 2 decades ago, I put my wristwatch in a drawer and 
left it there.

I was hoping to never have to use it again.

Wishful thinking.

Now I need it, but it does not work, battery is depleted.
I need to open it up and replace the battery.

Any idea how I get my Oysterquartz open. It does have a back cover,
but is it a right handed or a left handed thread, and where can I find 
the best tool,

without marring it ?

Also, any idea what the battery part number is ?

I should consider replacing the o-ring seal under the cover, any idea 
where to get one ?


After I replace the battery, I hope to calibrate it, comparing it to my 
Trimble GPS/DO.


Any help is appreciated.

I had considered getting support from R-USA in NY, but previous support 
was horribly bad.

Hello The Net:

Consider the HP-6235A triple power supply for a single T'Bolt.

Consider a HP-6236B triple power supply.
0-6V to 2.5A
0 to +/-20V  at 0.5A

Can drive 2 each T'Bolts, but not optimally at a cold start.
After the high cold start current draw, the +12V draw goes down nicely 
and then this PS

can nicely support 2 each T'Bolts.

Other have reported these as being quiet power suppklies.

Ebay can be your friend. do a search for either model.

Re: [time-nuts] LORAN C is good again tonight 90070

2010-12-22 Thread Stan, W1LE
When you hook up the SRS FS700 to the antenna you can monitor the front 
panel
LORAN  output with a spectrum analyzer and determine what has to be 
notched out
either in a separate multicoupler with high and low tunable notches like 
the Austron 2084

or the notch filters ( greater tuning range) built into the FS700.

My internet search a few days ago shows Loop Head in Ireland was never 
built/commissioned.


old mail:

Good Morning Claude,

I am assembling a K9AY terminated loop antenna, pointing to N. Europe. 
(~30 degrees)

Will use a ARR preamplifier at the antenna.

I hope to start listening later this month.

Some stations to listen for:
Lessay, France master on GRI 6731, Soustons France, slave X
BO , master on 7001, Jan Mayen, slave X, Berlevag slave Y
Sylt,  on 7499, Lessay, slave X,  Vaerlandet, slave Y
Eidi (Ejde) on 9007 master,   Jan Mayen slave W,BO slave X,
Vaerlandet slave Y



From my location on Cape Cod  FN41sr, looks like the closest active 
chain is Eidi with GRI of 9007

Eidi, IP62lh DX of 2900.1 miles
Jan Mayen,  IQ50pv,  2900.2 miles
Lessay,  IN99fd   at 3274.1 miles
Soustons,  IN93hr at 3412.4 miles,  (6731 GRI)

I have not calculated BO, and Berlevag details (7001 GRI) nor for the 
Sylt chain.


A google search on Loran C stations will show a listing of the few 
active stations

with the station details like RF power output and Lat/Long.
I have converted Lat/Long to 6 digit grid locator for my ease in LOB and
DX calculations with BD2004 software.

Sky wave propagation should be possible for the North Atlantic, European,
Western Russia, Saudi, and  Mediterranean chains.

Low likelihood of any ground wave and its better accuracies.
I miss my Nantucket Loran-C station and its Cs accuracies.

A modern Stanford Research Systems model FS700 Loran C receiver
is on hand as the receiver.

Re: [time-nuts] Time Code generator

2010-12-03 Thread Stan, W1LE

Hello The Net:

Another possible application is for a pocket digital recorder to 
generate a serial time code, record it,

and also allow 2 channels channels (stereo) of simultaneous audio recording.

One pocket digital recorder I am looking at is the Olympus model WS-500
(~ 70$ at New Egg)

It may not have Time-Nut (10 to the minus 12)  accuracy but it would 
serve
my purpose when recording/logging satellite QSO's in a portable 
operation with
a hand held full duplex, dual band walkie talkie and a hand held/pointed 
dual band yagi antenna.
Audio receive from the satellite downlink would be fed into one audio 
channel

and uplink audio would go to the other audio channel.
I could also live with only one audio channel for the downlink.

On playback the recorder indicates actual time of the recording being 
played back.
After the satellite pass, transcribe the recoded info, or archive it in 
a digital file.


The digital recorder is pocket size allowing hands free operation.
One hand to operate the transceiver and the other hand pointing the antenna.

I have not bought one  yet, but I suspect the archived audio file would
allow time stamping to be played back in the common PC media player 
applications.


Is the serial time code IRIG-A/B/C ?  maybe not,  but I can live with 
the existing time code format..

The person who asked the question didn't really state his intentions but
they seem very similar to my immediate needs. That is, simply a time
reference - that is the time, the start of the minute, and periodic
references (i.e. seconds) between the announcements.

It seems that recording the audio of something like WWV or CHU is ideal.

However, another approach would be recording a more proper time code
signal as you might have available from a precision clock. Of course,
a decoder would also be required.

A quick Google search turned up lots of leads which I have yet to sort
through. In the interim I thought I would pose the question to the
learned members of this group for their suggestions. Keep in mind KISS
and that a very high degree of accuracy is not required.

Is there an opensource/freeware PC app that will generate an appropriate
time code signal that can be recorded on one track of an audio recorder
(either PC based i.e. Audacity or standalone) that will also decode via
soundcard or other input?


Cheers, Graham ve3gtc

Re: [time-nuts] FS700 schematic

2010-11-22 Thread Stan, W1LE

It is not just one page.   What are you specifically looking for ?
Most sheets are B size ( double A size).

I got the complete manual from SRS for ~35$

Gentlemen,

I know this one has been asked a few years before but I give it another try:

Has anyone of you a Stanford Research FS700 schematic available that he can
share with me?

[time-nuts] Christmas Comes Early #1

2010-11-21 Thread Stan, W1LE

Hello The Net:

Excess to my needs is a National Instruments model: GPIB 232CT 64K,   
P/N: 180450-01 Rev B1


Looks to be a RS-232 to IEEE 488 controller (GPIB adapter) in a 
standalone box.


I do not have the wall wart power supply, but it uses +9VDC @ 700 mA max.
I do not have any drivers or any documentation, which should be on the 
NI website.


Connectors are for a female 25 pin D shell for the RS-232 and a female 
GPIB connector.


Does it work ?  I do not know.

Free to the first respondent who wants to pay the postage.
Should fit in one of those priority mail boxes with unlimited weight.

I grew up and got a Prologix USB to GPIB adapter and I have never looked 
back.

Re: [time-nuts] Yikes, WECO is hard to find

2010-11-03 Thread Stan, W1LE

Easier to cope with a female BNC, change it out.

Trompeter has adapters from the male WECO to BNC.

Long term solutions is to change it out to a BNC (female).

Did I mention it is easier to change it out
