all electrical devices if not properly shielded can produce interference with the station
already test if you have a little portable am radio (thing we had as child, if you're old enough ;-) )
just tune it away from any station and walk around, you'll notice rapidly the hums from motors, electrical wire etc, if you can find a clean spot where you hear near nothing, it most probably will work and up there I guess you'll 'see' thousands of kilometers, though accuracy at those distances will be pretty low, but all stations can help.
