A NEW DIRECTION FINDER employing a cathode-ray oscilloscope has been developed for planes by Donald G. Little, of Baltimore. As the loop antenna revolves, a circular wave pattern appears on the oscilloscope screen, which is calibrated to 360 degrees. When radio signals begin to come in, a depression appears in the pattern to indicate the direction from which they are being sent.
