Com-spec board
 

I have what I believe to be - the Com-Spec SS - 32 board here and have no
print out for it. It uses the 107 IC - resembles the TS - 32, but has no Q2.
Any info would be much appreciated. I am trying to wire the thing up for a
radio. There "appears" to be a jumper or two missing.

I've been looking at the Com-Spec site and can't seem to find the SS-32
info. I find only find the SS-32P/PA/SMT.

Anyone have the info on this?

I can send a photo of it for better match up - if need be.

You ever hear of Google? The very first hit for, "Comm spec ss-32"
gave me this site: http://www.hamrepeater.org/ss_32.cfm

Excuse me... I failed to add that the programming for the ss-32 is the
same as the ts-32.

yes I "have" heard of "Google". I've not found - yet - what I'm looking for.
It keeps coming up with everything "but".

I know that! I'm trying to get a copy of the "board" lay out, schematic and
hook up. As I said, this board has "A" transistor difference than the TS 32

I have that page already and something isn't quite right - THAT board shows
2 ICs, mine has 3.

The site I gave did have a board layout and hookup. Just how different
from that board layout is your slightly older unit? One or two IC's should
not make much difference from the overall layout already cited. This is a
simple CTCSS encoder. It only has three connections to it. There are only
three pins on that board, one for Ground, one for A+, and the output
pin. There will probably be a diode right off the A+ pin, the ground pin
should be obvious if you look at the underlying traces, and the output pin
will be off notabily separate from the A+ and ground pins and should be
capacitively fed.

You're most likely correct on that, but I was still trying to get the
"actual" schematic and whatever else I could scrounge up. I've contacted
Com-Spec. I've got the info on all their other units but this one. Amazing -
the confusion it is causing. Depending on the layout "you" forwarded -
showing 2 ICs instead of the 3 present - which I had already printed out
before your reference - and the TS 32 - which has 2 transistors and mine
only has 1 - and no - none were removed. Yeah, I had googled every hit I
could find - but couldn't find an "absolute" match to this board. It even
took me into some "ham" forums which had nothing more than chatter about
said board.

I can't wait to see their reply. Maybe they made "two" versions of the TS
32! I am not personally aware of that - but - who knows........ I mean -
their own chart indicates only (2) models used the IC on this board - yet
neither lay out that I've seen/found - seems to match up part for part! The
two models "they" claim - using this IC are - TS 32 and SS 32. Both are
obsolete (according to their records) - yet "Instruction sheets" are to be
available, which most of them "did" include board layout, schematic and
programming.

FWIW - I DO appreciate your help in this matter. I just wonder how long I
may have to wait for a reply. Some companies are pretty quick and others, I
have to wonder if they ever bother to check any e-mail! I've waited
sometimes "weeks" to get replies - if at all - from some companies. I'll
keep you posted on what I find out.

Please confirm, you are asking about an SS-32? Above, you made
mention of a TS-32..... The SS-32 is only an encoder. The TS-32 is
both encoder and decoder....

Concerning the above, be advised, I think Communications
Specialists was bought out by a larger firm. They may be slower in
getting old information because of this..... or maybe not.....

I really didn't want to do this, but I am pretty sure I have a bunch
of com-spec encoders and decoders in storage. I'll dig around sometime
tomorrow if I have the chance and see what I can dredge up.

I'll still need to know which you really are looking for.

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.
