- A motor emitting intermittent CWContinuous Wave? Among many things that are not a motor, this is likely some device directly related to RFRadio Frequency electronics creating harmonics, could be another receiver at the OP's shack, for example a hand-held scanner with battery saver at the lowest setting (highest duty cycle). I have a crappy Alinco DJ-X11 with oscillators emitting RFRadio Frequency all over the place in up to 30ft distance, creating nicely puzzling pseudo "beacon" (=intermittent) CWContinuous Wave signals.
