For the FM detection circuit, detection coil is able to use instead of ceramic discriminator. Recommended
circuit and recommended coil are as follows. In this case, please take care that V
Test Frequency
The AM Low-Cut action is carried out by the bypass of the high frequency
component of the positive-feedback signal at the AF AMP stage.
The external capacitor: C
