DRAWS - Sometime around 2018 a '
Hat' for the
Raspberry Pi computer was released and included a
free software package...The entire system is called DRAWS and replaces the need for a large computer and sound card (such as Signalink). Your digital comm can be accomplished with a tablet, the low power DRAWS unit and your radio...especially handy for those who want to backpack to their comm site and run off battery/solar.
