I used to check the output of the two way radios I was working on by
holding a fluorescent tube near or touching the contacts to the antenna.
CB radio rigs with illegal linear amps would really light one up. ^_^

Back in the 60's when I first got my ham ticket we'd always hear Loran
I figured that now with GPS it would no longer be used, but a quick
Google search shows it's still in use.
Sure liked those old days of vacuum tubes.
A friend of mine picked up a couple of WW-II radar sets and converted
them to 1296 mhz transceivers.
In 1965 that was quite an advanced project.
As to finding high-voltage arc-overs.
I still recall watching TV at a friend's house and him telling me that
his dad had to put a glass ash tray inside to prevent arcing over!
Yep. The T building that they "missed" is where I spent countless hours
during my year there. There was a 1/4 mile enclosed walkway from the
station to the T building. Call it an above ground tunnel. We had a couple
of old bicycles with big baskets as wide as the handlebars for carrying
parts to and from. There were a few lights along the wall so it wasn't
pitch black in the tunnel. Dark, but not pitch black.
One day lightening struck the tower and started a fire in the antenna
coupler inside the building. It also killed power to the building which
took out the lights in the tunnel. There was an small emergency light at
each end of the tunnel but for the most part the rest of the tunnel was now
When the alarm went off, being young, foolish and dedicated, I jumped on
one of the bicycles and headed for the T building down the long dark
tunnel. Those were my babies and I had to save them. Since I couldn't see
anything except for the faint light at the end of the tunnel, I leaned the
big basket against the ice covered wall and pedaled as fast as I could. I
had walked the tunnel so many times that I knew there was nothing to hit so
I just kept peddling as the light faded from behind me and kept going until
the light at the other end allowed me to see again.
I made it to building, grabbed a fire extinguisher from the front room,
felt the door to the transmitter room for heat, opened it slowly, went in
and emptied the CO2 into the antenna coupler. My heart sank as I saw the
burnt mass of copper tubing and ceramic resistors. Antenna couplers
_never_ go bad, so no one keeps a spare on site. I knew we would be off air
for at least a week. If a station is off air for more than one minute per
month, you have ruined a "perfect month". We had just gotten an award for 6
straight months of zero off air time. The run was now over...big time.
with all on is less than 100 watts. What I
want to do is to be able to connect my light
circuits to the UPS during emergencies like
this ice storm that is coming up. Not worried
about heat or the fridge, I have gas heater
backup and not enough in the fridge to worry
about. Are there approved ways of connecting
in the UPS that does not involve adding a transfer
switch. I was thinking about doing this with
outlets and plugs so I could unplug the light
circuit and plug it into the UPS.
I like your concept. I would also like to keep
my own lights on during power cuts. My best
advice is to invest in a couple flashlights and
wick lamps and some bottles of ultra pure.
It will not be as convenient, but it will be
dependable and provide a bit of heat.
I've heard of people stringing Christmas lights
around the house, run off a UPS or battery and
inverter. provides a bit of light for walking
Great idean! I think hospitals have dedicated outlets indicating 'normal'
vs 'ups'. Our electronic lab used to have clearly labeled outlets side by
side, like four instead of two, with the right half shown as a color
difference indicating the supply was from a UPS. Purpose was for powering
PC's and instrumentation performing life tests, to prevent a lifetest
dataset being ruined by an outage.
When I worked in the Security Industry, the UPS backup was specced to last
four hours minimum, industry standard at the time. You have NO idea how
difficult it is to power 120W for four hours without wanting to go to an
automobile battery, which wasn't allowed, but I did use a vehicle battery
on our internal backup system to power the PBS phones for the company.
You could use two battery packs, a generator to charge one while using the
other, and pretty much run for days. However, don't know how many UPS
systems allow you 'hot insertion' of a battery pack.
Another option of simple lighting, is to get those security lights that
turn on when power goes off. Great indicator of whether the power went
off, or on, and they're self-contained.

That sounds to me like he's not talking about plugging a couple
floor lamps into the UPS. If that's what he was doing, he
wouldn't be here. It sounds to me like he wants to take
existing light circuits in the house and put a plug on them
so he could plug that circuit into the UPS. And that sure

Yes, he could do that, provided it all complies with code.
I suspect the first problem is that it sounds like he already
has a garden variety UPS for use with a PC, etc and they
have outlets, ie they aren't rated or designed to be hardwired.

Your comments of following code, absolutely agree with!
Not because of fear of prosecution etc, but over time these codes have
come about due to some kind of accident. They represent a 'learned'
history of errors, thereofe learn from them and follow code.
Therefore, implement the'function' you describe! sounds like an excellent
idea. Just be careful, go about 'correctly' implementing that function.
Other than golf cart or marine trolling batteries,
what were effective for power storage?
Wonder if it's possible to use a generator and car
battery charger (off the 120 VAC generator socket)
to charge up the UPS batter while the UPS is still
I think the theatre and business power failure
lights can be good. Be nicer if you could wire the
internal battery to a big golf cart battery.

Buy a UPS that supports external battery packs and you are all set -
but they are NOT 12 volt units. Some are 24, some 36, and some 42 or
48 or more The external battery (extended run) units usually are
higher voltage than the self-contained.
My powerware Prestige 1000 is 48 volts - 4X12 volt batteries, and the
prestige 1000EXT is 60 volts - 5X12 volts.
The external packs "generally" have their own chrging system.
10 minutes on internal battery, 42 with external pack at rated load.
From memory, the 12 Vdc 4 A-hr Powersonics batteries. Bruno, their chief
engineer, taught me a LOT about battery chemistry and 'proper' charging
and overall care of a battery.
Parbly changed a lot since then. Today, there's not much reason to NOT
stick a chip in each rechargeable battery just to make everything a
Why change the battery to charge it??? Best Power had their "UBS"
systems - "Unlimited Battery System" - a DC generator super-charger
system that ran many police and emergency service dispatch systems
through hurricanes, earthquakes, blizards, and anything else you could
throw at them.
