Once you locate the discriminator in your scanner, you have to
make its output conveniently available on the exterior chassis,
much like a headphone or tape recorder jack.

Figure 1 below shows how to determine the pin numbering system
for most integrated circuits.  Looking at the marking side of
the chip, there is either a notch or nook at one end, and/or an
embedded "dot" off to one side at one end.  The notch, nook, or
dot signifies the end that starts with Pin #1 and ends with
whatever the highest numbered pin happens to be.  Most IC's have
8, 14, 16, or 18 pins.
