What commercial Linear Amplifiers will Hermes work with?
A. Since the basic Hermes board produces 500mW an intermediate PA will be required (e.g. Apollo or Pennywhistle) to increase this to a level suitable for driving a commercial Linear. At the 20W PEP level there are numerious amplifers that could be use. Hermes provides dedicated PTT outputs for driving switching a linear as well as seven open collector outputs that, via the PC GUI, can be used to select LPFs, antennas etc.
