You can't be serious-LOL- what an idiot. I've posted 555 circuits more
complicated than that joke you described...hahahaha....



Let's see you do it with nothing but 555's boozo.



Well you can make a good enough 1KHz oscillator with it, and a fair
operating temperature range. Was that unused audio channel 20KHz wide?
Then the CT will be tough to replace with a 555...but possible...what
voltage is on the beacon circuit?



It was 208 VAC, but why would it matter? All you are interested in
is the current. The only acceptable method was a CT. Therefore you used
it, or they wouldn't let you use it without spending wads of cash for UL
approval. All we had to do was open the breaker box and lift one wire to
feed through the CT. An outlet was added to one side of the breaker to
power the monitor and encoder. You had to be able to signal a power
failure at the remote site.

The two main audio channels were barely 10 KHz. The STL was
originally a telco microwave system design that the OEM modified for the
TV STL and CATV CARS market. They were about $20,000 new, and $15,000 if
you could find a used one. The more channels you used, the narrower they
had to be. The third channel was intended for intercom use by the
engineering staff, so it was a 5 KHz channel. If the 1 KHz sign wasn't
pre-filtered, it would have caused a buzz on the other audio circuits.
As far as a 555 timer for the source, the building wasn't air
conditioned after the old transmitter was mothballed, and wasn't
insulated very well. It was humid some days, and dry as a bone on
others so a 555 would have never passed the specs. The decoder had a 1%
lock range to reduce the chance of false triggering on the low level
modulation I had to use.

You had to do more than just monitor the lights to satisfy the FCC
and FAA. Every event had to be logged, in case of an incident.



Every what event? Beacon burn out? No on tower backups? Battery back-up?
Sounds fun, but hardly a major job...



That's it parade more of your ignorance. A failed lamp or beacon had
to be logged. Then you had 72 hours to fix it or face huge fines. If an
airplane hit the tower because the lights were defective, you would lose
big time. If all the tower lights were out for anything other than a
widespread power outage it had to be fixed yesterday. I am tired of
your lame *** from an anonymous coward, so it time to drop you back
into the dimbulb pit. You are too stupid to know that you are stupid,
and a lost cause.

Oooh my, aren't you so smart you *know* that complicated stuff. Sounds like the typical unskilled marginally performing lightweight piss-ant looking to ensure job security...how typical, now that does rate a YAWN...
