Why does the NCS occasionally perform a radio check broadcasting a call to the group call sign?

The National Control Station (NCS) performs a radio check by broadcasting a call to the group call sign primarily to verify that all users remain in contact with the network. This process is crucial for ensuring effective communication within the tactical environment, as it helps the NCS confirm that all units are operational and able to transmit and receive information as needed. By conducting these checks, the NCS can identify any issues that might hinder communication, such as equipment failures, and ensure that all members are capable of participating in the ongoing operations.

Maintaining consistent communication is vital in tactical situations where coordination among multiple units is necessary for mission success. By confirming connectivity and functionality through these radio checks, the NCS helps to support the overall communication strategy and operational readiness of the forces involved.
