 Just add and activate the [FGFS-addon](client/fgfs-addon/Readme.md) in your launcher (you can use FGCom-Mumble and the old FGCom in parallel).
 
 The FGFS protocol file will handle old 25kHz as well as newer 8.3kHz radios.

 The addon can be configured via a new entry in the *Multiplayer* menu.
 
 Your ADF will recognize transmissions in the kHz range. With enabled _ADF_-mode the indicated bearing is recognized and visible on the instrument. The plane's audio system may also playback the received analog audio signal. This is usually switched at your plane's audio panel.
