The TA7642 is not an identical ZN414 clone, and this is discussed further on. Electronics Australia, September 1987 This design was a switch tuned radio designed to fit into a cassette case. It uses the new improved gain control circuit. Unfortunately, the designer has made the mistake of connecting the 100K resistor so it shunts the tuned circuit.

Note this tuning is below the TA7642 150kHz low end. With AS3935 IC tuned to 500kHz, it also picks up AM radio and false triggers constantly when talk radio happens. Its Inductor MA5532 is 100uH Q=30 DCR=6R. Looking at other circuits, such as Wenzel uses a filter with 10mH and 1mH inductors.
