SingLe IC can be added to any receiver not having FM detector. Moving C2 from pin 9 to pin 10 gives higher audio output.Receivers having Less than 5 kHz IF bandwidth can be broadened by stagger-tuning IF strip slightly to improve audio clarity. Adjust tuned circuit of detector for maximum recovered audio.-I. Math, Math's Notes, CQ, June 1972, p 49-51 and 80.
