The newly developed Dittel 8.33 kHz generation radio transceiver is small, light, energy efficient and full of innovative digitalisation technology. The result of the high degree of digitalisation of the KRT2 is not only high frequency stability and channel separation, but also crystal-clear communication.

As a stand-alone transceiver for sport or ultralight aircraft, gliders and balloons or as a backup transceiver for larger aircraft (over 5,7t MTOW), the KRT2 makes radio communication a pleasure on all channels (depending on the quality of the connected headset and remote).

The advantages at a glance

  • 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 – Made in Germany

Functionality at its best

In addition to its high-end design, the KRT2 impresses with many characteristics, which raise radio communication in the cockpit to a high level and open the way to functional extensions in the future.

  • Dual watch technology: Beside the main frequency, it is also possible to listen to a second frequency
  • 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


  • Standard 2 1/4" (57mm) format
  • 6W output power
  • Selectable 8,33 kHz/25kHz channel spacing
  • 100 alfanumeric memories
  • Built-in intercom with adjustable VOX up to 4 headsets
