Frequently asked questions
The manual page " Installation instructions for TQ KRT2" bundles all instructions for the appropriate adapter variants – per navigation app, in up to 14 languages – including the entry you select in the app and the most common pitfalls.
All installation and setup instructions as well as data sheets can be found bundled on the Instructions & Downloads page – matching the radio and navigation app, as PDFs for download.
The SD-Link adapters are tested and compatible with the following navigation apps:
- SkyDemon
- Sky-Map
- VFRnav
- EasyVFR
- XCSoar
We'll explain step by step how to send frequencies from the app to the radio .
Yes, in addition to the TQ KRT2, there are SD-Link adapters for other devices:
Also, the SD-Link Universal Adapter for hobbyists and special setups.
Note: The Becker AR6201 is supported from serial number 3001 (NG version) onwards — older AR6201 models are not. The AR6211 (successor to the AR6201) is supported without serial number restrictions.
The model-specific, automatically updated list – including devices that are not compatible – can be found under Supported Devices.
9600 baud, 8N1. The TQ documentation mentions 115200 elsewhere – this is incorrect for operation with SD-Link and is the most common reason why a connection cannot be established initially.
Set the serial interface of the KRT2 to 9600 baud, then the adapter will connect reliably.
The plug-and-play adapters are simply inserted, not permanently installed – no modifications to the aircraft's wiring are required, and they can be removed at any time without leaving any residue. This is straightforward for ultralight and experimental aircraft.
The factual classification – also for certified aircraft (E-class) – can be found on the page Bluetooth adapters in airplanes: what is allowed?
