Seventy-five years ago this month, the July 1942 issue of Popular Mechanics carried the plans for this simple one-tube regenerative receiver. The set was designed with wartime parts shortages in mind, and most parts were non-critical, and could be found in most junk boxes. Future issues of the magazine would carry improvements, and most parts ...
How the AM Radio Circuit Works. When the reactance (AC resistance) of capacitor C2 is the same as the reactance of the coil L1, resonance occurs at the frequency f=1/2π√ (LC). For example, with L1 equal to 300 uH and C2 equal to 100 pF: F = 1/2π√ ( (0.0003 H)* (0.000000000001 F)) = 919kHz.
