What method of call sign identification is required for a station transmitting phone signals?

1. Send the call sign using CW or phone emission

2. Transmitting the call sign only via text

3. Sending the call sign in a single transmission

4. Using voice to announce the call sign

The correct answer is: Send the call sign using CW or phone emission

The method of call sign identification required for a station transmitting phone signals is to send the call sign using CW (Continuous Wave) or phone emission. This requirement ensures clear identification of the station's call sign, which is essential for legal and operational reasons in amateur radio. When transmitting in phone mode, the transmission of the call sign can be done verbally, typically at the beginning and end of each communication. However, the inclusion of CW as an identification method expands the options for operators, allowing the call sign to be transmitted in Morse code. This dual capability supports different operator preferences and enhances communication clarity. Other suggested methods, such as sending the call sign only via text or transmitting it in a single transmission, do not comply with the established regulations that dictate how identification must be communicated in amateur radio operations. Furthermore, methods that do not involve either voice or CW do not reflect the required standards for identification. Therefore, sending the call sign using CW or voice emission covers the necessary regulatory compliance for identifying the station during phone transmissions.
