I will describe here the USB interface between the radio station and the computer which I recently developed and tested. This post is a continuation of the first part, where I described a simple interface for controlling two digital lines using the USB / Serial Converter, where I presented simple interface to control two digital signals (e.g. Ptzt and CW). This time I will describe an interface that combines more functions:

  • Controlling several digital (switching) inputs and outputs
  • Interface for controlling the station via the serial interface
  • Audio input and output interface (sound card)

More details at Mare & Gal Electronics site.
