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.

SOLD TO JIM IN N.Y.---A very nice, approx.. 50 watt, reconstructed, Spark Gap Transmitter. This is a close copy of my Fathers Ham Transmitter of the 1900ís. Many of the original parts were used in the reconstruction. Battery post, ant. & grd. posts, key posts. Adjustable spark gap. His receiver was a Cohere receiver later a "Magnetic Detector" was used. Aprox. $20 shipping. Thanks for looking, Roger K8CIX, Airwave Explorer Labs "

SOLD TO JIM, N0XE---This is a very nice Telegraph sounder and resonator that my Grandfather used at a Rail Station Telegraph office in Northern Michigan in 1893. This was a hand built Resonator and Sounder combination. For local communication a low voltage battery source was used on the two wire system. For the single wire long distance line a battery box voltage of almost 500 volts was used depending on the ground conditions. When raining fewer batteries were spliced into the circuit. He told me to make the sounder louder he would set a Prince Alber pocket tobacco can behind the sounder. Sorry I donít have the tobacco can. I have completely reconditioned the resonator and the sounder is in excellent condition. Base is heavy and secures the Resonator from tiping over. Loud and working. Great museum piece or put your own Telegraph system in operation. Has pin connector post for the Telegraph Key and also the 3 thumb nut posts for battery and line connections. I donít know for sure the maker of the sounder. I believe my Father may have changed it to a more modern sounder sometime in the 1920ís. Possibility a Signal Electric Sounder, $105.00 + $11.00 shipping.----- Thanks Roger, K8CIX "
