Ok, I am about to pull my hair out. I have done every thing I know how to get Satpc32 to control my Yaesu FT-736r, but no luck. I have bought a usb cable for the yaesu ft-736, and still no luck. But, however, When I have the RTS+12v and the DTR+12v checked sometimes the “CAT Systems” light on the radio lights up; but the radio locks up, and can’t do nothing with it till I cut it off and back on.
I Bought a rs232 ttl converter, and still no luck. I am now thinking that I didn’t wire the ttl converter right.
Does anyone have a Yaesu FT-736r that is running satpc32 with no problems?

Stupid question. Does the CAT have to be enabled on the radio? Including baud rate? Does the serial port show up in device manager? (NO EXCLAMATION POINT)

Unfortunately, the 736R's CAT system takes over control of the radio. If you are saying that when CAT is active, you can't twiddle the knob or push the buttons, that's actually expected. When CAT is active, control of the radio is in the hands of the computer software, and the rig is giving it's undivided attention to what is coming in over the serial port..
If you are concerned that the computer software isn't able to control it, that's different. Seeing the CAT light turn on indicates that you do have some communication between PC and the rig. Now you need to verify the serial baud rate (which should be 4800, 8 bits, no parity, and 2 stop bits), and also that the software knows that it's talking to that type of rig. I don't use that particular software, so I can't advise you on the specifics there.
If all this checks out, your RS-232 converter might be the problem, but they're pretty simple. Make sure that it's inverting the voltage - a positive voltage on the serial port should be translated to a low TTL level. The circuit I use is a single NPN transistor, collector to the rig, emitter to ground, couple of k ohm resistor between the base and the computer serial port, with a diode between base and ground (cathode to the base).
Hope this helps,
