Radio Page
The Radio page integrates with TrackAudio and lets you manage your radio stack without leaving the vacs window. It is only available when TrackAudio is running and connected.
The Radio page is currently only available if the TrackAudio radio integration is selected in the transmit configuration. See Transmit Modes for more information.
The page remains inactive if you use the Audio for Vatsim radio integration.
Add a station​
To add a station, enter the desired callsign in the text field and hit enter or click the "+" button next to it. Manually adding a frequency is not supported.
This will only add the exact station you entered due to a limitation of the TrackAudio API. Adding all child stations automatically is not possible.
Removing a station is currently not supported due to a limitation of the TrackAudio API.
Frequency Object​
A frequency object represents a single station in its current state and controls its usage.
You can toggle receiving and transmitting by clicking either Rx or Tx. Clicking Tx automatically enables Rx.


If you actively receive or transmit on that station, the respective button will be blue.


By clicking the speaker icon, audio output can be toggled to the speaker device configured in TrackAudio.
The headset and speaker devices playing the radio transmissions are separate from the ones in vacs and need to be configured in TrackAudio.
Cross Coupling​
Two coupling modes are available, configurable in the Advanced Settings.
Original mode — Click CPL to enter Couple Mode, then click the desired frequency objects one by one. Click CPL again to exit Couple Mode. You can also double-click CPL outside of Couple Mode to immediately couple all TX-enabled frequencies at once.
In Original mode, do not click the Rx, Tx or speaker button when selecting frequencies to couple — click the left side of the frequency object instead.
Cross coupling automatically enables Tx and Rx.
Fast mode — Click FAST CPL to immediately couple all TX-enabled frequencies at once, without entering Couple Mode. The button label changes from CPL to FAST CPL when this mode is active. To uncouple an individual frequency in Fast mode, toggle its TX off.
A cross coupled frequency is indicated by two arrows next to the speaker.
