I had one. Used to get in trouble for taking it to school, too.
That was a crystal set. Had no power source other the signal being received over the air, used a single diode as a detector and had no amplification circuit. Fun to build or play with though. Those specific receivers were widely advertised in comic books in the 50s.This was the one I had when I was a kid. The silver part was the antenna, and it tuned in a station by raising and lowering it. It only picked up stations that were nearby, so I only got our one local radio station.

I had one. I used to take it to school where I wold slip it into my uniform pocket and try to camouflage the wire so I could listen to rock music. I was 11.In this day and age of head phones, ear buds and Iphones how many ever used a pocket sized transistor radio with one ear plug if you wanted to listen in private. Heck even the Sony Walkman with cassette is a relic at this point.
Mine had a tiny tinny speaker. I got it for Christmas in 1963 in less than two weeks my father hated it. I took the little earphone and cut the earphone off, stripped the wires and hooked it up to a bigger 3" speaker. It wouldn't get earschplittenloudenboomer loud, but for 1964 I was stoked......just listened to music over the radio's very tinny speaker.
