But interference can occur not just at the resonant freq at the antenna, but anywhere in the system in any module which has circuits, electronic components, or even metal parts which happen to be sized right, even wires... lots of chips, wires and components in those systems, you only have to hit one of them to goon it all up.
That's what I meant by winning the lottery 90 and 150 times a second (90/150Hz are modulation frequencies). It is virtually impossible to create a solid state offset by interference between a these two signals. It just does not happen.
