Work in progress - detector
Utilizes Dr. Stiffler SEC 15.1 with modified values. 470pf to base, L2 unknown inductance, which is wrapped on 3d coil form, trimmed by mm for tuning. L3 adjustable. Transistor - mpsa06
Detector part is a simple array of 2n3904 and 2n3906 npn,pnp transistors for gain, to switch on the led or buzzer. SEC is an advanced circuit, and must be properly tuned, all 3 coils with precisely tuned inductance,capacitance, resistance values, in order to achieve efficient
