NavProc is a Navtex mesage logging, filtering and display program. It allows selection of the display of received messages by either station ID and/or message type. It takes data from a separate reciever/decoder via the PCs COM port, and can also process captured text files of messages. It was developed for use with my home-brew Navtex stand-alone receiver, based on a design by Klaus Betke. Maps showing the location of Navtex stations can be displayed. The data files containing the station details can easily be updated with a text editor. The install package includes a manual in pdf format.
