RANDOM QUESTION -- does anybody know of software to *generate* IRIG time
code? Something in C that's adaptable to a modern micro would be good. In
something like a Raspberry Pi 3, IRIG generation would make a nice addition
to Lady Heather...

Well, I have an unfinished IRIG-B project here:

https://github.com/sa0mad/irigb

I have run that decoder in realtime from a Brandywine GPS4 IRIG-B output
on my Linux laptop.

Cheers,
Magnus

Look at util/tg.c or util/tg2.c in the ntp package.

I have built an irig b encoder. Irig uses a 1 KHZ amplitude modulated
signal. I can't remember now if it was pulse width modulation also. But it
used a small processor and todays arduino is many time more effective at
the job.
That said I used a modulator using a small xtal controlled divider to
produce the carrier. It was a Epson chip and even the xtal was built in and
a analog CMOS gate as the modulator.
Its actually fairly simple to create.
Then it was a case of reading out the clock in the correct format.

Paul.

[time-nuts] TymServe TS2100 dead power supply

[Mark Sims]

I once looked into adding IRIG generation to Lady Heather.   I never came up 
with a reliable / robust way to do it.  It could possibly be done with some of 
the Windows multi-media support, but that would leave the Linux/macOS/FreeBSD 
people in the dark.

I just added TS2100 support to Lady Heather... but it only reads the time code 
output string and drives the clock displays.   I don't have a TS2100 to 
properly test it, but it works when fed with a simulation file.

Re: [time-nuts] TymServe TS2100 dead power supply

[Bob Martin]

Many thanks for the replies on this one.

Before I made the first post, I'd pulled the supply, given it a visual and 
nasal inspection, checked the outputs for shorts, and powered it up on the 
bench. Dead (and dead quiet, not even the tick-tick-tick of a switcher with a 
shorted output).

In my perusal of the archives, someone observed that it was a standard Astec 
LPT-42 supply. Lo and behold, a label on the primary filter cap of my dead 
switcher identifies it as an ASTEC LPT42.

I looked around -- Mouser and Digi-Key were within $1 of each other. Not too 
surprising, actually, pretty much ALL the sellers on eBay wanted more for units 
of dubious heritage than Mouser and Digi-Key wanted for a new one.

Already had some bits and pieces I needed from Digi Key so I added a new LPT-42 
on to the order.

New supply arrived. Installed, connected power, turned it on and things light 
up. Pulled the fuse out of the old supply to save and tossed the old supply in 
the bin. Last time I got a good electrical shock (if there is such a thing) was 
from a faulty switching power supply; another reason to diagnose this one with 
my wallet!

Back in operation again. Yes, I *still* have to deal with the old GPS module 
and the issues it creates. But my TS2100 is back on the air, driving my IRIG 
displays and providing 10 MHz to various pieces of equipment.

Something in C that's adaptable to a modern micro would be good. In something 
like a Raspberry Pi 3, IRIG generation would make a nice addition to Lady 
Heather...

Classic sign of bad electrolytics.
Several comments.
I have had equipment with small switchers that were separate form the
mother board.
Often an actual supply could be found cheap.
When I can't its time to check the caps. Really cheap to replace.

Bob,
Just a reminder, as it came from the factory, this unit has a week rollover
issue unless it has been upgraded.  Check out the TN archives and Google
for the upgrade fix suggestions. (mine was in a production installation
when the rollover occurred, and the resulting pain seems to be forever
etched in my mind.)


Luke.

Re: [time-nuts] TymServe TS2100 dead power supply

[Clint Jay]

If it's not restarted after a power down and there's no 'ticking' sound
from it then it's likely to be a problem with the bootstrap supply,
switchers will run for years once they're running but while they're running
the small capacitor (of the order of 47uF) and the resistor that feeds it
(often 220K-470K but can be outside that range) will dry up or go high in
value and as soon as you power it down and try to restart, it fails because
that little circuit doesn't provide the supply needed to kick the chip into
life.

First order of business, check the rails on the secondary for shorts
(tantalums have been mentioned by someone else) and then, after making sure
the main reservoir capacitor is discharged, check and high value resistors
and low voltage/value capacitors on the primary.

The data sheet for SMPSU control chips like the UC3844 usually have a
reference circuit which is often copied by SMPSU manufacturers with only
minor component changes.

First check for power / ground shorts on the power supply outputs with an ohm 
meter.   There is a good chance of a shorted tantalum cap somewhere in the 
system shutting down the supply.  If the power supply is connected to the 
system via a connector,  disconnect it from the system and see if the supply 
puts out anything.

[time-nuts] TymServe TS2100 dead power supply

[Bob Martin]

We had a brief power outage a few days ago.

My TS2100 didn't power up afterwards. Fuses are fine, AC power delivered to 
power supply, which is producing nothing. Nothing looks/smells fried on the 
power supply.

Couldn't find data on what the power supply output voltages should be; not in 
the meagre documentation, .

I'd appreciate help from someone with a TS2100 while I look for faults in this 
little switching power supply. Looks like three voltages, +5 and what else? Is 
this a more or less standard supply?

Appreciate any help I can get!
