MacRadioSchedule is the computerized shortwave schedule package for the Macintosh.
A listing of shortwave transmissions is presented, with broadcasts presently on the air highlighted.
In addition, MacRadioSchedule can communicate with your radio using a RigTalk package, such as my MacIcomControl. In this case, you just click on a transmission, and your radio is automatically set to the desired frequency.
MacRadioSchedule requires a Mac with a color display (minimum resolution 640 by 480 pixels). System 7 or greater.
