Which of the following is common practice during net operations to get the immediate attention of the net control station when reporting an emergency?

Starting a transmission with "Priority" or "Emergency" followed by your call sign is the standard procedure during net operations for reporting an emergency. This method quickly conveys the urgency of the situation to net control, allowing them to prioritize and respond appropriately. The use of specific terms like "Priority" or "Emergency" is crucial as it is universally recognized in the amateur radio community, ensuring that all operators understand the seriousness of the report.

By identifying the nature of the communication right at the beginning, it sets the tone for immediate action, guiding net control and other operators to respond in a timely manner. This practice also helps maintain the organization and flow of communications during emergencies, which is critical for effective management of the situation.

Other approaches, like repeating SOS or using tones, may not be as universally recognized or efficient in conveying the need for immediate assistance, making clear, verbal communication indispensable in an emergency context.
