Clarification needed:
The schematic below is for a DB25, I said it fits in DB9. This is correct
except that pin numbers on DB9 are different.

Actually, if you don't plan to poll the squelch or S-meter (the only commands
that cause the 736 to send data to the computer), you can leave out Q2 and all
the components associated with it. That leaves just one transistor, and one
resistor. I put a small diode in series with the resistor, so as to not
reverse-bias the base of Q1.
My 736R has served me very well. The power supply has held up just fine, so
far. I do have a 2m / 70cm pair of "brick" amplifiers for the cases where I
need a flame thrower, but with a decent antenna, these are not often used. I
also managed to find a 1.2 ghz module, so I'm all set. (I have 6m on my aging
Yaesu 767GX transceiver.)
The biggest disappointment is that the CAT interface does not let the computer
read where the frequency dial is set, and you can't move the dial when under
CAT control. This is not an issue for FM birds, but it makes computer control
of SSB/CW awkward, and I usually just run those modes manually.

I guess no one considers the FT-847, yet I consider it superior rig
to the venerable FT-736R. I comes ready to interface DB-9 RS232
jack. Only issue is it is now out of production. They show up used
on e-bay at about $900-1100.
I briefly considered selling mine to upgrade to a Elecraft-K3, but
the cost to acquire 2m and 70cm xvtrs, and other things made keeping
the FT-847 financially/functionally smarter. I'm mainly interested
in the K3 for extreme weak-signal EME, VHF+ and 160m/600m work, and,
of course, a superior HF rig to the FT-847. But the FT-847 shines as
a satellite rig...so keeping it.

I agree the FT-847 is a fine radio. I have also owned one, but I got
such a good deal on an Icom IC-910H that I couldn't resist; and had to
sell the 847 to get the funds to buy it.
The 847 hasn't been mentioned, because the original poster stated that
he wanted to buy a new satellite radio, so I believe that he means
brand new.
I would prefer the 847 over the 736, simply because it has HF, and has
higher power on VHF/UHF; plus it is a newer radio, and is very easy to
interface to a computer.
But really, when you consider the going price for a used 736, or a
used 847; for just a little more, you can get a new IC-910H, with a
warranty, and have a rig that is still in production. But if you find
one at a good price, I wouldn't hesitate to recommend it.

Bearing in mind that computers don't come with an RS232 interface, TTL levels
are actually easier than 232 voltage
levels to interface.
A USB-serial chip is already TTL and of the correct polarity without adding
the +-12V generator and interface.

I agree, it's a great satellite radio, but I always used it with
manual tuning :-)
However it has a lot, and I mean a lot of more or less strong birdies
on the 2m band.
Also the power switch fails too soon and too often if you use the
original yaesu part.
I also noticed that NB has almost no effect on the typical impulse
noise that is silenced by all other NB of my other rigs. This NB
problem has been confirmed by another friend owning the FT-847 (I
still have to go and listen for the 2m birdies).

OK, good observations.
The very early production of the radio had a problem of either solder
flux residue or improperly tightened screws on the audio board, that
resulted in internal birdies. Mine was a 1999 radio and I sent it
back to Yaesu to correct that. They cured a lot of birdies (not
all). Most of my birdies are eliminated with an external preamp, so
that leads me to conclude they are generated external to the radio in
the shack. Placing a 50-ohm termination on the antenna connector can
confirm this. The Kenwood TS2000 birdies on popular satellite freq.
is a much worse fault in my mind.
My power switch failed at about the 5th year and I simply rewired to
the extra contacts (its a DPST switch) and has cured the problem, so
far (note my radio is now ten years old). The NB is a
disappointment. I had a FT-842 HF radio that had a terrific NB. Why
Yaesu couldn't copy the design is beyond me. So if your main use is
for a mobile radio perhaps the new 857 or 897 is better. I don't
have a lot ignition noise issues in my home station (occasionally,
snow machiners), so I overlook this.
The DSP NR and filters work well. Especially on CW. But this is an
area that I expect the K3 is probably much better. I do mainly EME
and MS so my needs are much greater for Rx performance. For
satellite work that is generally dealing with stronger signals, the
FT-847 works quite fine. I thought it was fine for AO-40! I use it
less for the Leos, though that will change later this year when I get
my satellite antennas back up (also, planning to add a dual-band
Lindenblad). I have auto-track/tuning that was never implemented and
expect that to make mode-LS on Leos easier (high-rate Doppler changes).
I now have 175 stations worked on 2m-EME with the FT-847.

I made several contacts over Friday and Saturday

If you logged me over the weekend could you send the info offline

Mystery solved.
I asked Charles about the SSTV picture he sent yesterday, he said during the
15:20 UTC pass over Boston 4/6/09, The picture is of a Russian designed
toilet, located in one of the American modules.
It looks like ISS now as at least two Toilets.

I intend to operate on the satellites AO-51, AO-27 and SO-50 with my handheld
Yaesu VX-7R and vertical antenna
AL-800 during my stay in Peru 11-19th April 2009. I will use callsigns
9A5YY/OA4 from Lima and as 9A5YY/OA7
from Cuzco. I will be limited with time because of other obligations. I hope I
will succeed to do some satellite QSOs.
Please, listen and respond me when you hear my CQ on the birds!

Is anyone using the beta of Ham Radio Deluxe (V 4.1, Build 1989) that includes

If so, will you please contact me offline? I'd like to have someone walk me

tuning" Doppler offset.
Thanks in advance, and 73 to all,
