Heh. Funny story about that. Back in the early 80s when our amateur
packet radio club was setting up a high speed (56kbps!) wireless
network in the Atlanta area, I got the idea of using a refrigerator as
an environmental chamber. We used a PC as the packet switch and it
required pretty good temperature control. We'd been given a spot at
the 800 ft level of Ch 11's broadcast tower. I realized that the
fridge would make a fine chamber. The equipment heat would warm it in
winter and the refrigeration would cool it in summer.
Here are some photos of the fridge going up the tower:
The tower had a tiny elevator, too small to handle the 'fridge so we
slung it under the cab with rope.
Another guy in the group came up with another whacky idea. We painted
a couple of paint cans black and glued them along with some black PVC
pipe to the refrigerator. It looked like a giant handi-talkie!
That thing stayed up there about a year until one day when the news
chopper's live cam didn't have any blood'n'gore to broadcast. He flew
around the tower zoomed in on the "handi-talkie" for a few minutes.
The station manager had a cow. He vaguely knew that one of his
engineers was involved with amateur radio and was using the tower. He
apparently didn't realize it involved a refrigerator. He didn't give
us time to get it down properly so we went up one blustery winter day,
cut the fridge up with a demolition saw and pushed it over the side.
