I've never been in that position, but over the years I've bought many other
things in similar situation.

That's a nice attitude, it's good to see that in the world. I know that is
small comfort, but it means a lot about you.

Ok, without pictures, it's hard to tell. It may be different expectations.

Did you ask if the seller actually used in on SSB? I know several people
both here and the U.S. that do not have microphones on their HF rigs. If
there was a disaster and they needed them, they could find them in about
a minute, but they never use them, so they sit in a drawer. It's the same
for me with a key. I have them, but due to an injury they never get used
and probably never will unless my younger sons show an interest in them.

That seems pretty normal. A 20 year old anything probably needs some sort
of rebuild due to lubricants drying up, whether it's a PTO, camera, car,
etc.

With no idea of what it looks like, could just be a sloppy soldering job
when it was replaced. Not everyone is good at producing neat solder joints
and if it worked and was in no danger of shorting out, there was probably
no reason to replace or reinsulate the wire. Or maybe the person at the
factory was new, or had a bad day, etc. IMHO if it works, don't fix it.
Since it is inside the radio, no one will notice.

Dirty connection/poor solder joint on the SO-239? I'm not familure with
the rig, maybe a bad PIN diode or dirty T/R relay contacts?
Maybe someone at Ten-Tec did have a bad day. While I'm sure you could
find the 20db difference because of comparison with another receiver,
they seller may have never noticed. I am amazed that my Argo 509, Triton
IV (Digital), TR-5, TS-430, and R-5000 all read within one S unit. It
doesn't mean much and without the comparison, I'd never know.
> So what to do now?
What do you want to do? Besides the 20db down and the PTO, what is wrong?
Does the speech processor not work, or have other problems?

That may be the key, you're angry at being "took" and no matter what you
do to the radio you will always be angry. Or not, it's up to you.

Does it really matter? Except for a reduced sensitity problem, and the PTO,
will it work for you? Will opening it up and checking for bad solder joints
and loose connectors, a spray here and there with tuner cleaner and if you
really feel like investing some effort, a spray of Tri-Flow (is that's
what it's called) make it into a good "user" for you?
Is it worth an hour of your time? Two? Five? $10, $50, $100, $200? Set a limit
and see what you can do in that time.

Sounds like a bad idea to me. It will just keep making you angry. Maybe not,
a dishwasher I bought for 1/3 of the price of a new one, which was supposed
to work, popped the GFI when we ran the first load. A friend of mine who
repairs them for a living spent three hours fixing it (I spend as much time
or more fixing his computer). While he was doing it I found that someone
had dumped a pound of detergent in the water softener making it impossible
to fix without a $100 part.
Since my friend had it apart, I took it in the bathroom and with a toothbrush
removed the detergent. The unit works fine now and we use it everyday.

I think that's what it boils down to. It's a question of how you feel about it.
The Ten-Tec route is the simplest, you just throw money at it. That gives
you a good working radio, but it has negative sentimental value, (it makes
you feel bad to see it), so that's probably the worst option.
If it were my radio, I would spend an hour on it. I would spray lube the
PTO and clean the contacts I thought might be the problem. If I had access
to replacment PIN diodes and they were not SMT, I'd replace them.
That's about as far as I would go. If it worked, I'd keep it. If it did not,
I'd sell it. If you have an active community on 2m, you might just ask around
and find someone who enjoys fixing radios who would love to do it for the
fun of it.
I'd take it as is, but I don't have the money to pay for the shipping if
you gave it to me. I'm sure if you look around, you'll find someone with
a similar desire who would make you happy financialy.
73,
Geoff.
