Jetzt haut nicht gleich auf mich ein .
Ich bin im Netz auf diesen Text gestossen aber verstehe
ihn nicht ganz.
There is no standard discriminator output on the AR1500 /E/EX models. However it is possible to obtain discriminator (detector) output by wiring directly to the NFM discriminator chip, this is IC 3 MC3372 pin 9 located on the i.f. PCB (the larger SMD chip on the underside of the board, pin 1 is marked with a dot/circle - count pin numbers anti-clockwise).
A suitable ground may be taken from almost and point close to whatever socket you mount on the unit to provide a durable connection or use pin 15 on IC3 MC3372.
Depending upon the loading of your external circuit, you may need to buffed the connection to the discriminator with a capacitor, resistor or both (otherwise it may result in little or no audio output from the receiver).
Könnte mir jemand diesen text verständlich machen.
Ich weiss das ich nerve aber ihr seid meine einzige Hilfe
