Communicating with YAAC

Once you have configured YAAC, you can start communicating through it.

The main window of YAAC displays a geographical map, upon which located APRS stations and objects will be plotted. Other views are available and can be selected from the View menu. The main window also has other menu options for locating specific stations and sending messages to those stations.

The first two buttons above the map control zooming in and out. The third button pans the map to the local station's position. The fourth button pans to latitude/longitude (0,0) (also known as the Coast of Africa), where stations who have not transmitted their position yet will be plotted until their position is updated. The map's current view can also be adjusted from the keyboard with the following keyboard keys:

An area at the bottom left of the main window displays the current coordinates (in degrees latitude and longitude, and Maidenhead grid locator) of the mouse cursor position on the map. The remainder of the bottom contains fields for composing arbitrary short messages to send to other stations.
