ALLSTAR / HAMVOIP

A purpose-built radio-to-USB interface for AllStar Link and HamVOIP.

The RI-1 is designed for use with AllStar Link or HamVOIP systems. It connects the radio through a DB-9 female connector and is designed to work with modified USB audio FOBs.

An onboard LM386 amplifier provides additional transmit-audio drive for radios that need more modulation level. Most setups can run from USB 5 V; additional amplifier drive can be supplied when required by the installation.
