A theory - the interference caused by magic could be substantially
different than normal radio interference in that it "hangs" in the air
rather than radiating from a specific source. That means A) it would
not effect anywhere outside the hogwarts grounds B) it would be inside
any shielding that a computer/etc may have. Before you say
interference doesn't work that way, remember - it's magic.
