Gary,
Do you have a FC-20 auto tuner attached? If so, remove the FC-20 connector, and turn the rig off and back on. The auto tuner and CAT port use the same circuitry and are, with some caveats, incompatible.
Some _very_ early models did not have a bi-directional CAT port, which would certainly cause a problem with a CAT program, and possibly with a cloning program expecting a bi-directional port.
You seem to have eliminated all the usual cable and port configuration glitches.
