    When Looking thru the various Models of Crystal Radio in my eBay store, you
    will see a number of Radio coil Design Variations such as Litz, Enamel, and Center Tap Coils.
    I offer these Variations because many Crystal Radio Enthusiasts often prefer one type of coil design over another.
    While all of the Coil Designs Perform well in the AM Medium Wave Frequencies, my cost to manufacture these coils
    vary and you will see some slight Cost Differences in the selling price depending on the Model.
