Adjustment of the demodulator circuit is obtained with an IF signal which is higher than the 3 dB limiting level; L2 should be short-circuited or detuned;
L1 should be adjusted to minimum d2 distortion, and then L2 to minimum d2 distortion.
(1) Coil data: L1 = L2 = 0.38 µH; Qo = 70; coil former KAN (C).
