DXbase includes a built in interface for most RS232 controllable rotors.  These include ARSWIN, HD-1780, HYG-CDU1, Orion M2, Sartek, Prosistel, and most Yaesu.  Support is provided through a serial port on your computer.  With one click of an ICON on the rotor toolbar, you can turn your rotor to short path, long path, bump up or down 5 degrees, or enter a beam heading directly.  DXbase also provides a built in city database which you can modify as you wish.  Turn your rotor to any of the cities you have listed with just a couple clicks.  DXbase supports two rotors on separate serial ports.  Just click an ICON to switch between rotor-1 or rotor-2.
