Which of the following must be programmed into a D-STAR digital transceiver before transmitting?

• A. Your call sign
• B. Your output power
• C. The codec type being used
• D. All these choices are correct

Answer: (A)

In a D-STAR digital transceiver, it is crucial to program your call sign before transmitting because this is how other operators identify you on the air. The call sign is a primary regulatory requirement for amateur radio transmissions as it provides your unique identifier to meet FCC rules. While options such as output power and codec type may also need to be set for proper operation and preferred audio quality, they are not mandated before every transmission. The output power can generally be adjusted according to conditions or preferences, and the codec type, which determines the method of encoding and compressing audio, could vary based on the operator's choice and the standard used. However, the call sign remains a fixed requirement in all transmissions to ensure compliance with amateur radio regulations. Thus, the necessity of programming your call sign makes it the essential element to be configured in a D-STAR digital transceiver prior to transmitting, reinforcing the importance of proper identification in amateur radio operations.
