The USB-II interface by microHAM is an enhancement to the popular first USB-interface. 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/Vista, Apple Macintosh OS8/OS9/OS-X and Linux (with limitations, only from Kernel 2.6.17.8 on). MS-DOS is not supported.

Unlike common computer mass market "USB to Serial adapters" our USB Interfaces are carefully designed for maximum immunity from strong RFI and at the same time be "RF quiet". Each data line is low pass filtered for minimum interference. The only known product of USB chipset clock is a beat at 144.030MHz.
