RDF Mapper is a tool for visualising bearings produced by a pseudo-doppler radio direction finder (or other bearing finding hardware). It was originally written to work with the PA8W doppler RDF.

At a minimum, the RDF Mapper requires a doppler RDF receiver which can output bearings over a serial (or USB serial) link. Additionally the mapper can take advantage of a serial (or USB serial) GPS dongle. With the GPS dongle enabled, the software will calculate heading and adjust the bearing plotting as you move around. This is particularly useful for applications where the doppler array is mounted on a vehicle.
All configuration is done through the settings screen. The RDF and GPS serial devices can be selected, along with their baud rate. Once they're started the data coming from them will be visible in the terminals on the settings screen. The GPS device needs to output NMEA frames, and the RDF should output bearings with the format
The main screen of the RDF Mapper shows the map, the current position (from GPS) and the bearing lines (from RDF). In the top right are some map controls. At the top are zoom in and out buttons (keyboard + and -). Next, the button which resembles a target, centres the map on the current position (keyboard c), and the button below toggles whether or not the map moves with the current position (keyboard l). Finally, the bottom button removes all current bearing lines (keyboard space). The map can be moved by clicking and dragging, or using the arrow keys. The map controls can be seen in action here.
RDF Mapper is written using the Processing.org framework and the Unfolding library. There are some compatibility issues with Unfolding and Processing3 which will hopefully be resolved as the Unfolding project progresses. These can result in the software failing to render maps on some systems.
