Question
Which of the following is required in the identification transmissions from a balloon-borne telemetry station?
Answer Options
- A) Call sign
- B) The output power of the balloon transmitter
- C) The station’s six-character Maidenhead grid locator
- D) All these choices are correct
Correct Answer: A
Explanation
Balloon-borne amateur radio stations (often carrying telemetry and other data) operate under a specific set of rules. The primary rule for station identification applies even to these automatically controlled, one-way transmissions to ensure that the source of the signal can always be traced and monitored. The identification must be transmitted in a format that is readable by the public.
The only piece of information that is strictly required in the identification transmissions from a balloon-borne telemetry station is the call sign of the operator or licensee. While other data like location or power might be included as part of the transmitted telemetry, only the call sign is a mandatory part of the official station identification requirement.
