Step 1: Circuit and Theory Here is a scan of the circuit from the book. The circuit is actually pretty simple, just two variable capacitors (C1 & C2), a coil (L) with 8 taps and a tap switch (S), a detector (D) and a set of phones (P). By J.W.

In this case, his radio was from the late 30s. He was able to find the original data from Radiomuseum.org. He painstakin… The equation for calculating the capacitance to resonate with this inductor is: where 2π = 6.28; F = frequency; and L = inductance. For the inductor given above, the equation becomes: where F = 1510 kHz (1.51 x 10 6) and C = 224 pF (224 x 10 -12 Farad). The closest standard value is 220 pF.
