Adding a discriminator output to a UBC120XLT, UBC220XLT, Commtel COM214 or Albrecht AE95H is similar to
that of an AE65H / BC60XLT / COM212.
The UBC120XLT/220XLT also uses an SMD-version of the
MC3361, with the demodulated audio at pin 9.
This pin is a little hard to reach, because a small PCB
is mounted on the main PCB right next to the 3361. The limiting
resistor (in this case 5.6 k) is fixed to the IC with a drop of
glue from a glue gun. There is ample space for a 3.5 mm chassis
A small piece of insulated wire connects the other lead
of the resistor to the 3.5 mm chassis terminal, which is mounted
at the side of the scanner's back panel. The ground lug of the
chassis terminal is connected to the shield in the back panel.
When the scanner is closed, this shield is connected to the
