This requires a little more hardware, but makes it extremely difficult to detect. Of course, there are a minimum of three transmissions per move (here is a move, was this the move sent, yes/no), but the responses sent could be made variable in time (i.e. this could all be done automatically until the proper move was recorded, but the time delay between signals could be made random).
