I can't see why not. One of my first projects with my shiny new Tandy 200-in-1 kit was an AM transmitter. I remember very well the awe in speaking into the crystal earpiece and hearing it loud and clear on the Stereo. Probably 35 years ago now. Stuff like that sticks with you forever.

I guess the difference with that was poking wires into springs while following a diagram, vs the Silicon Chip one requiring soldering and construction and therefore some Adult supervision / assistance. The beauty of the old 200-in-1 was I didn't need to seek any parental help to do whatever I liked with it :)

None the less, kits are getting less and less theoretical and more "just plug the blocks together", so anything that goes back to basics like that can't be bad.

I wonder at if it has appeal, given that most kids can now talk over 100s of kilometers..

It isn't like back in the day, when a shortwave allowed you to listen to the word, and it seemed only the state or large companies could TX.
Gaze not into the abyss, lest you become recognized as an abyss domain expert, and they expect you keep gazing into the damn thing.

Could be a fun project. Uses a MC1496 RF mixer chip - beloved of Theremin builders.

But AM is becoming increasingly rare on radios - whereas FM is more common.

It is also difficult for a beginner to build and adjust an efficient antenna for ~1 MHz.

On a range achieved per component basis, I think there's a lot to be said for FM bugs.

Good audio, efficient antennas, more people have radios that can tune it and better range (>200 metres).

http://www.talkingelectronics.com/projects/FM-BugsIntro/FM-BugsIntro.html is a good introduction.
