Which of the following is true when making a test transmission?

Making a test transmission while operating a ham radio requires adherence to specific regulations regarding station identification. The correct statement highlights the necessity of identifying your station at least every ten minutes during the transmission, as well as at the end of the test.

This requirement is in place to ensure that users of the radio spectrum can identify who is operating within that frequency range, thus maintaining accountability and aiding in communication clarity. In the context of Amateur Radio, regulations mandate that operators must announce their call sign at prescribed intervals so that listeners can recognize who is transmitting. This helps prevent interference, allows for proper frequency management, and contributes to safety in operating procedures.

The inclusion of identification at the end of a test transmission is also important because it allows any listeners to know that the test communication has concluded and to expect ordinary operation or silence thereafter.
