-This mode blinks the current LED, alternatively from black to the current active color, when throttle is below 50% and the craft is armed.

 #### Larson Scanner (Cylon Effect)
 
 The Larson Scanner replicates the scanning "eye" effect seen on the mechanical Cylons and on Kitt from Knight Rider.
 This overlay dims all of the LEDs it is assigned to and brightens certain ones at certain times in accordance with the animation. The animation is active regardless of arm state. 
 
+#### VTX Frequency
+
+This overlay makes the LED color dependent on the current channel of the VTX, in case it is equipped with SmartAudio or IRC Tramp.
+The color is selected according to the following table:
+
+ Frequency range | Default color | Color index
+ ------------ | ------------- | -------------
+ <= 5672 |  White | 1
+ |> 5672 <= 5711 |  Red | 2
+ |> 5711 <= 5750 | Orange | 3

+ |> 5867 <= 5906 | Dark violet | 11
+ |> 5906 | Deep pink | 13

+The default color can be changed by double-clicking the color and moving the Hue slider or by using the color command in the CLI.

 #### Thrust state
 
-This mode fades the LED current LED color to the previous/next color in the HSB color space depending on throttle stick position.  When the throttle is in the middle position the color is unaffected, thus it can be mixed with orientation colors to indicate orientation and throttle at the same time.  Thrust should normally be combined with Color or Mode/Orientation.
