  • Very high frequency stability and channel separation – under all operating conditions
  • Spectacular low weight of just 360 grams – ideal for gliders and ultralights
  • Compact dimensions – for easy and flexible installation
  • Minimized power consumption – optimized for battery operation in gliders and balloons
  • Crystal-clear voice transmission – for perfect communication
  • Large, high-contrast, long-life TFT colour display for excellent readability – even in direct sunlight
  • Intuitive controls – developed by pilots for pilots
  • Outstanding price/performance ratio


  • Dual watch technology: Beside the main frequency, it is also possible to listen to a second frequency – with adjustable tone and volume control.
  • Speech controlled intercom: Two headsets or loudspeakers with microphones (standard or dynamic) can be connected with the optionally available cable harness
  • 100 freely assignable frequency memories with 8-character, plain-text display: saves the re-entry of often used frequencies
  • Automatic squelch function: the threshold can be adjusted manually
  • Additional AF input: can be used, for example, for warning messages from anti-collision systems (Flarm, ADS-B)
  • Future-proof multi-functionality: through the possibility of firmware upgrades
