The pictures confirm my suspicions. You have been mixing apples and
oranges, so to speak. In your original post you asked for info on an SS-
32. More recently, you were talking about the TS-32. Those are two
different animals. The SS-32 is only an encoder, is physically smaller,
and missing some circuitry including an IC.

What you have is a TS-32, both encode and decodes CTCSS tones. It can
be referenced at : http://www.com-spec.com/insheet/ts32skm.pdf .

Even if you are using the decoder part of the boarad, in all likelyhood
you have no need for the missing Q2. Q1 is an output transistor for the
tone decoder.... it sinks current. One would only use Q2 if you needed to
source current ( a logic inverter function ). If you really needed it,
just stick in a cheap switching NPN like a 2N2222.
