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.

After I had sent this last post with pictures, I did what I probably
should have done at the onset! I went and took a good LONG look at the
board again. In the TS 32 paperwork I have - it shows two transistors - Q1
and Q2. I don't have the paperwork now in front of me, but I recall they
are "outputs" for the function you stated - one doing so a tad differently
than the other. Otherwise, I was able to pull out all the connections
needed.

Thanks!


But still, I am curious - where the Q2 came in - in the paperwork such as
you referenced - which I already had - and the board "I" have - which
doesn't have a Q2.
