Hi You probably can get kits...but you can diy your own as well. Google for circuits for crystal radios. I seem to recall there is a site dedicated to them. A book as well. Some are quite simple and some rather complex. Obtaining parts can be an issue. Things like the crystal (high sensitivity ) headphones and tuning capacitor if it uses one can be a challenge. The crystal itself is often now replaced with a germanium diode...often a type 1n34 or 1n34a.
