The New Version Of The Crystal Radio Initiative Calculator Is Out!

The new version of the Crystal Radio Initiative Calculator boasts a completely redesigned front end, making it even easier to use!

The Crystal Radio Initiative Calculator now features measurement units selection, reducing the clutter on screen and allowing you to display only the units that you’re working with.

Crystal Radio Initiative Calculator Features:

  • Calculate all your Crystal Radio Initiative coil dimensions according to Eric Dollard’s equations from as few as two numbers input
  • NEW: Units selection from dropdown menu
  • Optional primary coil dimensions input for simplifying the design process
  • Calculate the secondary and primary conductor surface area
  • Calculate the primary coil inductance and approximate tuning capacitance
  • Magnification Factor calculation
  • Coil frame groove details

The Advanced Crystal Radio Initiative Calculator takes things even further and includes:

  • NEW: Illustrative diagram with positioned overlay measurements which update in real-time with units selection (only available in the Excel version)
  • Primary and secondary total and active copper weight based on the calculated conduction depth
  • Optional primary hollow conductor input for calculating total copper weight
  • Fully integrated coil analysis – enter your measured frequency for the Magnification Factor section and the calculator will take care of the rest!
