Radio Navigation comes from the days when we carried RDF (Radio Direction Finder) on board the vessel.
And at that time there were Radio Beacons along the coast lines, marking the entrance of every harbor and headland. Due to the advent of Loran & GPS this method of Navigation has been pretty much abandoned. But if you are lucky enough to have an RDF, then you can use the well plotted antennas of the commercial radio stations that are along the coast lines. And get a radio bearing on any vessel that is transmitting on any freq that your RDF covers.
Note: Loran C has been abandoned by the stupidity of our government also... and that leaves three method of Navigation; Celestrial, GPS, and Coast piloting. And GPS can be dithered or turned off by the Military if they deem it necessary for national defense. And that leaves Two Methods.....
