try unplug all cables from your computer. plug one cable every time and try
to find the "bad" one. Put some ferrites on this cable until the problem
will be solved. Be careful to use no 43 or no31 ferrites. All ferrites are
not the same. It is good if you plan your shack such a way so coax is as far
as possible from computer or control cables. In any case coax must not run
in parall with computer-control cables. GL
