What does it spend its time doing, ie what would it transmit, or be listening for? I was under the impression that just soft-blocking was enough to stop radios from operating, hence airplane mode (though it is a mystery to me why even the FM radio in my mobile phone won't operate in airplane mode). Lurching OT: anyone here use nextradio on their mobile phone? Cheers, David.
