Came across this.
Would be pretty cheap to add parts to a good crystal radio to your preps. Would be absolutely one of those things to get the young kids involved with and a foot in the door with a good prepping skill for them.
What is everyone's thoughts? Am I beating a dead horse? Or is this completely a dumb idea?
