Why is the clock on a compulsorily equipped ship radiotelegraph station required to have a sweep second hand?

🔍 Key Concepts

• Radiotelegraph distress procedures and the purpose of compulsory equipment • How silent periods on distress frequencies are observed and timed • What the auto-alarm system does and whether the operator manually times its signals

💭 Think About

• Think about which operations on a radiotelegraph distress frequency actually require an operator to watch seconds, not just minutes. • Ask yourself: during a silent period, what exactly must be timed, and how precise does that timing need to be? • Consider whether the auto-alarm signals are generated and timed automatically or if the operator must manually measure the length of dashes and spaces.

✅ Before You Answer

• Verify what activities during silent periods need accurate second-by-second timing. • Check whether auto-alarm timing is handled by equipment or by the operator using the clock. • Confirm which operation explicitly requires a sweep second hand per radiotelegraph regulations.
