"CRYSTAL RADIOS AND SPARK GAP TRANSMITTERS"

"Built to order by, AIRWAVE EXPLORER LABS"

Come visit the Airwave Explore Laboratory!!

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 almost 60 years now. This has given me the experience to handbuild 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. 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

"Beautiful Rotary Spark Gap"

Beautiful Rotary Spark Gap. This is powered by Thomas A. Edison, Company of Orange, N.J. Motor. This motor is either A/C or D/C and is switched by a switch mounted at the rear of the motor assembly near the speed governor. Motor leads come out to two binding posts on the side of the unit. The motor has a speed control via a lever operated governor. Cup type lubricators are mounted on each end bearing assembly. Bearings, mounts, brushes and holders are in perfect condition. All governor and brush assembly parts are servicable from outside the motor case. Brushes are standard and available at local hardware stores. These are easily replaced with no tools other then your fingers. Rotary Electrode Wheel is high temperature composition material and has 8 contacting points. Fixed contacts are mounted on Christmas tree insulators and are fully adjustable for spacing to rotary electrode wheel contacts. Insulation factor for the high-voltage is 50 KV +. Motor is also insulated from the mounting board and is also shock mounted. The mounting platform is a beautiful piece of Black Walnut with only an oil finish. Four rubber feet on the bottom of the board protect your workspace. The Spark Gap Unit measures, Base = 12in. x 6.5in., Total height is 8in., Rotary Wheel diameter is 5in., Weight is 9 lbs. but with the special shipping box I have designed, shipping weight will be 14 lbs.
