These are a sample of some of the Crystal Radios I build. My Father and Uncle had a shop in Jackson, Michigan from 1919 until 1929. They designed and built custom Crystal Radios to sell. I am attempting to relive those Golden Times & Days of Radio by following in their footsteps. I have been a Ham Radio Operator for over 65 years now. This has given me the experience to hand build these radios. I am trying to follow the schematics and designs my Father used. I use as many vintage parts as I can. I try to always use old tongue and groove, box joint, finger joint and dove tail boxes. I test and "Pot" my own crystals. I can build you a radio per your specifications or mine. Using your box or mine. These spark gap transmitters are meant to be for display. Not to be connected to an antenna or ground and operated. It is illegal to operate a spark gap transmitter. I accept, PAY PAL, checks, or Money Orders. So light up that old oil lamp, put on your headphones and travel back in time to the Golden Age of Radio. PLACE CURSOR ON PICTURE FOR MORE INFORMATION
