What's in this update

  • Now it is possible to couple the keyer with a Station Master via iLINK c​onnection. It allows to merge their PTT sequencers and transfer decoded CAT fr​equency from keyer to Station Master.
  • Optionally paddle can generate CW in VOICE mode too. In this case the PTT pattern for CW mode is used.
