Rick,
 What you have sounds like a classic case of RF in the shack to me, as
you surmised. A long wire type of antenna tends to exhibit such
characteristics unless you can provide a good counterpoise for it to
operate against.
 Sometimes just changing bands will give an indication of this. By that
I mean that you may observe an improvement in the situation by trying a
different (probably higher) band. Eighty and forty meters I suspect
would be the worst because an additional problem may exist. That is,
coupling of the radiated RF into the AC mains. Your house wiring may be
acting like a great receiving antenna, coupling large RF voltages into
the power supply of your Kay-Pro!
A brute force line filter may be the solution in such a case. You might
also try reducing the output power just to see if this has an effect on
performance just to verify that RF is the cause.

 I hope I have helped a little- this type of problem can be a real
s.o.b. to solve.
