Hi, Can you turn an electric (DC) motor into a powerful R.F. oscillator? I see that an ordinary motor is already an oscillator which produces noises in the receiver, but One that produces a sharp, distinct, recognizable signal (or noise) (of any frequency) in a receiver? I just don't want to use any electronic components bcuz I can just take to those simple a.m transmitters if I used transistors and condensers.. an 'electrical' method would do. Thanks.
