Operating Modes : Radio Direction Finding
  • A new method of radio direction finding Priority listing - A method of finding radio sources with antennas based on omni-directionality (the less directional the better coverage). Uses energy levels and some sophisticated math (encompassed in a free software download on the site) to find x,y,z coordinates of the fox relative to the center of your antenna array. Can be overlayed on a GPS map to help you locate in real-time.
