What is the International voice SAR on-scene frequency?

• A. 3024.4 kHz
• B. 5680 kHz
• C. 2670 kHz
• D. 4000 kHz

Answer: (A)

In SAR operations, there is a single internationally designated on-scene voice channel to coordinate all units at the scene. That channel is 3,024.4 kHz, placed in the MF/HF band to provide reliable long-range voice communications so ships and aircraft from different nations can talk to each other and stay coordinated during the rescue effort. Using this specific frequency ensures everyone involved can establish contact on a common channel, reducing confusion and improving response time. The other frequencies are not the internationally designated on-scene channel and may be used for different services or bands, so they don’t provide the standardized on-scene coordination need.
