Mac Grayliner

Mac Grayliner displays a map of the entire Earth, showing day, night, and more importantly, the terminator between day and night. Studies have shown that enhanced radio propagation occurs between two points which are both on the day/night terminator. Now with version 2.1.1, the locations of active NCDXF/IARU beacons can be displayed in real time, along with the beacon callsign, country, and location. This should be helpful for identifying DX openings. Mac Grayliner requires a Mac with a color display. Shareware: $15 Chris Smolinski
