Aluminum doesn't shield from magnetic fields. Maybe the aluminum case isn't stopping the RF interference? I don't know! This is sort of hilarious.

Here's what I don't get. EMI is electro-magnetic interference. Once it's flying through the air, what does the aluminum enclosure block? Can it block only the electrical part? That doesn't make any sense to me at all. electricity and magnitism are 2 aspects of the same phenomenon. How do you stop it?! Maybe the enclosure needs to be steel? I have no idea what I'm talking about!
