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

Look at util/tg.c or
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
I once looked into adding IRIG generation to Lady Heather. I never came up

I just added TS2100 support to Lady
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).

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
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
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
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
