DF Plotter 1.1

DF Plotter can determine and display the direction of any transmission using a simple passive antenna switch. This allows voice transmissions from aircraft or other similar radio signals transmissions to be located and displayed on a chart. DF Plotter displays the direction of a radio transmission picked up by your receiver.DF Plotter can drive a passive antenna switch and display the direction (QDM) of any aircraft voice transmission or similar radio signal. DF Plotter can display waypoints, tracks or routes over the current chart using data from a user-defined GPX format file. DF Plotter can send its direction finding information to another remote instance of DF Plotter using UDP/IP datagrams. If both machines are connected to a suitable receiver, antenna and antenna switch, then the DF bearings from both will appear on their respective displays permitting a precise location for the transmitter.
