Here is a modern day version of a superheterodyne radio. I built one in electronics class years ago and it was a blast.

That's not a bad design, can you give us a link for more detail. E.g., for the dual-ganged tuning cap and the tracking of the local oscillator with the RF tuning, etc.

A good place to start would be here:

http://www.crystalradio.net/

Also, Google "crystal radio kits". I saw some inexpensive ones there.

A crystal, some wire (whisker+coil), and a speaker (or headphones).

That's a crystal radio.

Check it out on Wikipedia: http://en.wikipedia.org/wiki/Crystal_radio (Which has different languages as well)

C.P.

Had one of those when I was a kid. Not very loud, but when attached to a radiator the reception and volume was good enough to listen to while falling asleep. Simple and rewarding to build as a kid.

A soldering iron might be useful.
