The new USB-II interface by microHAM is an enhancement to the popular USB-interface (see above). This interface offers the usual level converters for nearly all CAT interfaces, electrically isolated lines for PTT and CW keying, an input for a squelch signal and electrically isolated audio interfaces. This makes this device ideally suited for all users who wants to run digital modes from the soundcard.

The microHAM USB-II device works with all comouters with USB interface, drivers are available for Windows 98SE/ME/2000/XP, Apple Macintosh OS8/OS9/OS-X and Linux. MS-DOS is not supported.
