An Arduino based SSPA display controler for HPSDR/Hermes familly This module controls

  • voltage
  • current
  • temperature
  • VSWR/PWR
  • cooling fan
  • 4x40 lcd display and shuts down the Bias current while beeping in case of dificulties

This board and the associated firmware have been developped by ON7EQ.

http://www.qsl.net/on7eq/projects/arduino_sspa.htm

Some code modifications have been made by John Melton for the Hermes familly.

The design of this board uses the generic output names used by all Hermes/Angelia boards and could directly be plugged on the Alexandrie control board

So far, NO SSPA and NO Reflectometer/Refl-fwd coupler have been designed. A multipurpose 33dB Tandem Match coupler is under development (for both VSWR/PWR measurement and predistorsion -aka "pure signal"- sampling)

3D image of the board are stored on this repo
