That's where I'd start. Is there a ground loop through the AC supply, for instance? I've seen this sort of thing happen when you get a current on the outside of the coax, and the effects show up more at high power - I suppose because the magnitude is greater. Another possibility is some harmonic output from the amp. But I've seen from funny things with ground loops that misbehaved at high power, but not at low.
