About using the map

Radio Explorer features a map, which displays your home location and the locations of radio stations’ transmitters. The map is in the azimuthal equidistant projection.

You can center the map on any location, zoom in on the map to get a close‑up view, or zoom out to see more of the map at a reduced size. The map also features the optional display of the twilight zone, also known as the greyline, and the optional display of zoned MUF coloring.

More information is available on the Map view page.
