Others like Bill Brown dabble with transmissions from Storm Chasing Near Space by means of Amateur Radio High Altitude Balloons (ARHAB). The “payload” may be a simple transmitter or it may be combined with with other experiments. Tracking the balloon to retrieve the payload requires Amateur Radio skill in direction-finding and using FAA winds aloft data to predict the landing zone.
