I was a kid during the "energy crisis" of 1974, which is why a lot of what's going on today just feels like acid-indigestion deja vu. At school we were supposed to learn about energy and things we could do to use less power, where electricity and energy comes on, that sort of thing.
My dad was an electronics tech and he asks, you want a project? How about a radio that doesn't need electricity to run? You don't plug it in and it doesn't need batteries? Sure.
So (and this is via my hazy memory, so it wouldn't stand up in court), we took a Quaker Oaks box, a spool of copper wire, did a little math and wound a coil, which was mounted on a square foot of plywood. One end of the coil went to a post where a wire snaked out my bedroom window and hooked up to a metal bar that was my antenna; the other wire went through the same window and went to a metal stake that was stuck in the flower bed. A metal bar with a screw in it was used to tap the coil; we used a diode for the detector, and a couple more posts that hooked up a pair of old high-impedance headphones (the kind you see people wearing in World War II movies).
We lived near the transmitter for KFI in Los Angeles, which was (and still is) a 50,000 watt clear-channel station on 640 kHz AM. My father said the signal was so strong it would wipe out anything else on my set, but in practice I was able to pick up 570 (by moving the tap), and I think I sometimes got the other 50 kilowatt behemoth, XTRA 690, which blew in strong after dark from its transmitter in Tijuana, Mexico.
I'd fall asleep listening to the radio at night, and sometimes listen in the mornings when I woke up. If my parents didn't check on me, I'd wake up in the middle of the night with sore ears from those hard, unpadded high-Z headphones. At the time KFI was a Top 40 station so I'd hear music, but I picked up the Laker games on 570, and more music on XTRA. In the mornings I'd get the Farm Report and the legendary morning team of Lohman & Barkley.
I don't have the crystal set anymore, but I kept listening to radios. I had a number of smallish transitors and one of those big 4-band jobs that picked up nothing but static on the non-broadcast band, but fueled dreams of exotic stations and broadcasts I couldn't pick up with the "normal" radios. These days I still listen to the radio—mainly in the car or podcasts of shows I can play while I work.
I love old radios. It's like darkroom work in photography—you can do so much more with modern equipment and methods, but it's not as satisfying. I've tried internet radio and I can get all kinds of stations from all over the world with wonderful sound quality; but when you're sitting in the dark with nothing but the glow of the dial lights and maybe some vacuum tubes, you're sitting there making tiny adjustments via your fingertips on knobs, trying to project yourself a thousand miles to pick out a voice through static and atmospherics; it's just not the same looking at a web page and tapping a mouse.
That's also why I like old hollow-state stuff over solid-state and more modern equipment. The new stuff is fantastic and easy, but I feel insulated from the process. I'll admit that I'm often frustrated at the results I get; there's a big part of me that's spoiled with modern electronics and doesn't like getting static-y sound, doesn't like working to pick out an interesting broadcast only to have it fade away a minute later; doesn't like turning through 6 linear dial feet of white noise to find the only thing I can pick up is a religious sermon; doesn't like the fact that picking up a foreign-language broadcast is exotic and fun for about 1 minute until I realize I have no idea what they're talking about and never will. But I still enjoy it, and there's always the hope that the next night I'll get something good.
There aren't many radios in my collection, yet they seem to dominate my house. I also collect photographic light meters, and all of my light meters (and I have many) take up less space than just my Transoceanics. Like a lot of people, I'm stuck for space and every time I acquire something new, I have to figure out how to stay off the TV show Hoarders.
