This is an 2 in 1 crystal radio, that I made; FIG. 1 - is a crystal radio for use with crystal headphones, and FIG 2 - is a crystal radio for use with crystal earphones. The ANTENNA connection connects to the ANTENNA connector in FIG 2. The GROUND connection in FIG 1 - connects to the GROUND connection in FIG 2.
FIG 1 - tunes a frequency radio wave from the AM radio band. FIG 2 - tunes the strong and weak radio stations from the frequency radio wave.
The 2 in 1 crystal radio can now receive 4 times or more, radio stations, and it is easy to build.
Many crystal radio parts can be purchased at www.crystalradiosupply.com/index1.html (Crystal Radio Supply) to build a crystal radio.
