The\n    Simple Crystal Diode Radio Sets we have for sale are a fun way for the family to spend time together. As a child I\n    made Crystal Radio Receivers out of things I find in old scrapped Radios and TVs. Most had no tuning capacitors. I\n    had to tune in stations by sliding a ferrite rod in and out of the tuning coil. I would spend days trying different\n    items to use as a detector instead of a diode, some worked but most did not. Anyway I had fun learning.
