HOOKUP PROCEDURE
If you need the raw Discriminator baseband audio signal for external purposes, the best way to access it is via
a jack installed in a convenient, unobtrusive location on the scanner.
1. Install an RCA or other jack in a desired place on the scanner’s external case, typically the rear panel.
2. Connect the shell or outer frame part of the jack to scanner chassis ground.
3. Connect the (+) leg of a 2.2-uF tantalum capacitor to the Discriminator output Pin. (Capacitor should be
tantalum, but can vary in value from 1.0-uF to 10-uF at a voltage rating of 25-50vdc.)

+ center conductor
4.Connect the center conductor of a shielded coax (RG-174, etc) or shielded mic cable to the (-) leg of the
capacitor.
5.Connect the shield of the cable at this end to a nearby PCB ground trace or spot.
6.Connect the center conductor of the other end of this cable to the center or hot lug of the jack.
7.Connect the shield of the cable at that end to the ground lug of the jack.
8.Fabricate or buy a shielded patch cable with one end to mate with the new jack on the rear of the scanner at
that end....and the other end to mate with whatever jack is on the tape recorder, processor, decoder, or
whatever device is to be connected at the other end.
