Description
Funke ATR833 Bluetooth adapter for SkyDemon, Sky-Map and other navigation apps — SD-ATR833-E.
The adapter functions as an intermediate plug and is simply inserted between the radio and the Sub-D connector of a Funke ATR833 VHF transceiver — without any additional wiring or mechanical work. Afterwards, you set the standby and active frequencies of your radio directly from the app via Bluetooth Low Energy (BLE).
Additionally, the adapter offers a V24 data interface (multi-drop) at pin 9 of the outgoing connector for other devices. This plug-and-play solution allows, for example, the integration of an autopilot or AV-30 display — an optional expansion.
Key Features
- Compatibility: Designed for the Funke ATR833. Compatible with ATR833-S, ATR833-A, and ATR833-II-OLED, running on Android and iOS. Usable only with radios running software version SW 5.8 or higher—older versions (SW 5.7 and lower) are not supported. You can check if your device has SW 5.8 by looking at the serial number: the first supported unit has serial number 40131610 (production year 2010). Tip: The last two digits of the serial number indicate the production year—devices with lower numbers may require a software update from the manufacturer.
- Simple installation: The adapter is plugged into the existing wiring and stays securely attached to the housing thanks to the Conec-Latch system.
- Power supply: No additional power supply required; processes on-board voltages up to 28 V. An integrated fuse protects in case of a fault — the radio remains operational.
- Requirements: Works on the 12V and 24V Avionics bus.
- Compact design: Dimensions 59 × 50 × 17 mm, Weight 60 gr.
Important note: This product is intended for experimental purposes only. Our page " Bluetooth adapters in aircraft: what is allowed?" explains what this means for UL, experimental, and certified aircraft.

Everything worked wonderfully!
The adapter works flawlessly and fits perfectly. A quick tip for other users: On my Samsung S25 with Android, I had to enable location services for the adapter to be found immediately. With only Bluetooth enabled, my smartphone didn't detect the adapter for several minutes. As soon as I enabled location services, it was found within seconds, and adding it was seamless.
Reconnecting after turning off the radio or smartphone also works perfectly – the devices connect automatically and the frequency is transmitted immediately.
Thank you so much! This is really awesome and will improve my flying experience by leaps and bounds!

I received my SD-Link last week. From uncrewing my instrument panel to pairing it with SkyDemon and trying it out took all of 5 minutes! Brilliant! You've taken plug & play to the next level.

Great service. Took a few days to get through the post but arrived well packaged, with simple instructions. 2minute job to install, and configure. Much tidier than the other options of separate dongle / power etc which need wiring in to the radio loom and power. Click click... job done.
Not really much else to say, as it works as described. Superb. Would recommend.

I highly recommend it. The entire installation took just a few minutes and was completely problem-free. Operation has also been seamless so far. 100% effective.
Now running on over 60 flights with a total duration of over 40 hours. It's truly a tremendous relief to simply press the right frequency on the tablet (the name is in front of it). Another advantage: always having the right frequencies, not potentially outdated ones from paper charts or your own lists.
I am very satisfied and really excited.

The adapter arrived promptly and was installed in seconds – it works flawlessly. It's a well-designed, reliable device that delivers exactly as promised. I've already demonstrated it to fellow gyrocopter pilots, and I'm sure more orders will follow soon. A fantastic solution for seamless connectivity in the cockpit. Highly recommended!

The Bluetooth adapter arrived much sooner than expected – a great surprise! I installed it on my aircraft the same evening, and it works perfectly. This is probably the best solution I've come across for this use case. Highly recommended!
He also kindly shared some great photos for our gallery – thank you, Dan!

Installation was very easy and quick – absolutely straightforward. I had originally planned to build my own adapter, but yours is clearly the better solution. The integrated power supply is a real bonus! Thanks for such a well-thought-out design.

So much neater than a blue tooth adapter, additional USB power supply.
Plugged in and worked perfectly

The adapter fits. Many people at our airfield in Marl are already enthusiastic – we now have five SD-Links in use.
