When are you required to transmit your assigned call sign?

The requirement to transmit your assigned call sign at least every 10 minutes during and at the end of a communication is rooted in FCC regulations that ensure proper identification of licensed operators in amateur radio. This rule is essential for several reasons:

Firstly, transmitting your call sign allows others in the communications spectrum to identify who is operating the station, promoting accountability and encouraging compliance with FCC regulations. It ensures that all operators are identifiable, which is crucial for the integrity of the amateur radio service.

Moreover, the rule of identifying every 10 minutes helps to minimize confusion, especially during longer transmissions. Regular identification reassures other operators that the station is still active and helps to maintain an orderly flow of communication.

In the context of amateur radio practice, consistently identifying with your call sign conforms to good operating procedures and fosters a respectful environment among operators. Thus, maintaining the discipline of timed identification enhances cooperation and reduces the potential for interference or misunderstanding during exchanges.
