USB Interface II

Package contains:
micro USB Interface II™, CD ROM with drivers, control software and manual, USB A-B cable, two sound card cables, and one optional radio cable (specify your radio).
microHAM USB Interface II™ includes full optical isolation of all control signals (radio control, CW, PTT and Squelch) and high quality audio isolation transformers with level trimmers (screwdriver adjust) to permit connecting a computer sound card to your radio's rear panel audio input and constant level audio output for use with digital mode software or echolink.
microHAM USB Interfaces have built-in hardware support for your radio - you no longer need additional level converters like CT-62, IF-232, FIF-232, CT-17. The drivers include support for software CW keying (DTR) and PTT (RTS) - there is no need for additional interfaces.
