Description: NEW High Tech solution for Crystal Radio applicationsThese work Great !!Build your own Crystal Radio without the need to wind a wire coilThis Auction For Only One Circuit Board- Does not include any Radio or other parts.You can see how I use a Green Version of the PC Board in my own designs in the Photo Gallery ALSO AVAILABLE IN GREEN AND BLACK AND WHTE IN MY EBAY STORE Multilayer PCB 54mm x 96mm FR-4, 1.6mm Thick One 350uh Planar Spiral Multilayer Printed Circuit Board (“PCB”) coil that simulates a Crystal Radio coil formed from Litz or Enamel wire.Because of the compactness, the design permits Multiple Circuit Board Coils to be stacked and wired in Series or Parallel to increase or decrease the overall circuit inductance.Some amazing inductance results can be achieved when stacking these pc boards.I have experimented with coils wired in series and stacked on top of each other.The amazing thing is that depending on the spacing distance between the boards, the inductance will vary from 645 to 1000 uh. This Coil has all of the copper windings etched onto the top and bottom surface of the Circuit Board. The PCB is fabricated using a very precise manufacturing process to produce a copper trace that is constructed with a 6 mil Rectangular Double Spiral Coil on both sides of the PC Board with 6 mil clearance.
