The Handic 0050 is a vintage scanner, and as it is a
pre-SMD scanner, it's not a big deal to add a discriminator
output. The discriminator IC is a DIL Motorola MC3357, with the
unfiltered audio on pin 9. |

| A resistor of 10 k is soldered to pin 9 of the MC3357.
This resistor can be mounted vertically. A piece of wire connects
the other lead of the resistor to a 3.5 mm chassis terminal
mounted in the back of the scanner. As the back panel is grounded
and it's only a short distance to the resistor, shielded cable is
not necessary. |
