Is it battery powered or does it have a wall wart or direct wall plug?
Which bands seem to be worse?  I would try ferrites with as many turns as
possible on every wire into it first.  Remember, a single clip on ferrite or
a single pass through a core doesn't provide much attenuation at hf.  Then
try wrapping it in aluminum foil and maybe shielding the cable to the
outside probe.
