The Cub Scouts Ozark Trails Pack 83 pack leader asked me to
help with the crystal radio project. I was very interested to
help because crystal radio is how I got started with radio and
electronics.
.
The boys each wound their own coil on a PCV pipe form, then
connected it to a 1N34A germanium diode for a detector, a
crystal earphone to listen with, and an antenna wire we ran
outside, and a ground wire inside the building. It worked!
The volume level was very low, but we could hear the local
AM radio station KTTR (1490 kHz).
