Dynon SV-COM Adapter - with the SD-SV-COM connect your Dynon SV-COM radio seamlessly with SkyDemonSky-Map, VFRnav or easyVFR. Frequencies can be transferred directly from the navigation app to the radio – conveniently, quickly and without manual input on the radio.

Important: The SD-SV-COM is designed for Dynon SV-COM radios that have a Dynon SV-COM-PANEL to be controlled.
Support is provided in particular SV-COM-425, SV-COM-760, SV-COM-T83, SV-COM-T25, SV-COM-X25 and SV-COM-X83, provided an SV-COM-PANEL is used for operation.
Dynon SV-COM Adapter: The plug-and-play solution
The Dynon SV-COM Adapter SD-SV-COM is a compact Bluetooth Low Energy adapter for Dynon SV-COM radios. The adapter simply plugs into the existing cabling of the Dynon SV-COM panel. No additional power supply is required.
The adapter injects the frequency commands from the navigation app into the communication between the radio and the SV-COM-PANEL. This allows frequencies to be transmitted directly from SkyDemon or compatible apps to the radio.

FAQ about the Dynon SV-COM adapter
-
Which Dynon radios is the SD-SV-COM compatible with?
The SD-SV-COM is designed for Dynon SV-COM radios that have a Dynon SV-COM-PANEL to be controlled.
Support is provided in particular for:
- SV-COM-425
- SV-COM-760
- SV-COM-T83
- SV-COM-T25
- SV-COM-X25
- SV-COM-X83
Crucially, the radio must be operated via an SV-COM-PANEL. -
Do I absolutely need a Dynon SV-COM-PANEL?
Yes. The SD-SV-COM is designed as an intermediate adapter for installations with Dynon SV-COM-PANEL designed.
The adapter is integrated into the existing connection between the radio and the panel. This plug-and-play integration is not possible without the SV-COM-PANEL. -
Is an additional power supply required?
No. The SD-SV-COM does not require a separate power supply.
The adapter is powered via the existing connection and is suitable for 12V and 24V electrical systems. -
Do I need to solder, crimp, or modify the avionics wiring?
No. The adapter is designed as a plug-and-play solution.
It is simply plugged in between the existing wiring and the Dynon SV-COM system. No additional electrical or mechanical work is required. -
Which apps are compatible with the SD-SV-COM?
The adapter uses the Garmin-GTR225 compatible protocol.
This makes it compatible with navigation apps that support this protocol, including:
- SkyDemon
- Sky Map
- VFRnav
- easyVFR
In SkyDemon, the device type is usually displayed. “Garmin GTR225 Compatible” selected. -
What happens to normal operation via the Dynon panel?
Normal operation via the Dynon SV-COM-PANEL remains available.
The SD-SV-COM simply adds the ability to transmit frequencies via Bluetooth from a navigation app to the existing installation. -
Is the SD-SV-COM also compatible with Dynon SkyView HDX?
Yes, provided the radio is integrated via a Dynon SV-COM-PANEL.
An existing Dynon SkyView™ HDX system is seamlessly integrated. The existing installation remains intact. -
Do you also support other radio devices?
Yes, in addition to Dynon SV-COM, there are SD-Link adapters for other devices:
- spark ATR833
- uAvionix AV-30
- Becker AR620X
- TQ KRT2
- TRIG TY91/92
Außerdem gibt es den SD-Link Universal Adapter for special setups and custom integrations. -
