| {{ menu }} → {{ settings }} → Sensors → Add sensor → DSC Radio |

### Sensor Connection

The sensor connection and setup are performed in accordance with the {doc}`procedure </sections/sensors/navigation-sensors/index>`.

### Message Processing Setup

When configuring the sensor, ensure that received message processing is correctly configured:

- Header and message type processing is enabled
- Checksum verification is enabled

### DDCS Message Identification

DDCS message headers must contain:

- **CD** — digital selective calling (DSC)

This allows the system to identify incoming messages as DDCS data.

After configuring and enabling the DDCS sensor, the **DSC Target** window will become available in the **Multifunction window**.

```{caution}
Some radio station models have a built-in GNSS receiver.

The manufacturer does not recommend using the radio station's built-in receiver as a positioning sensor due to its unpredictable behavior and low position accuracy.
