Q

When testing is conducted on 2182 kHz or Ch-16, testing should not continue for more than ______ in any 5-minute period.

🔍 Key Concepts

• Distress and calling frequencies such as 2182 kHz and VHF Channel 16 are kept as clear as possible • Routine testing transmissions are allowed but must be short and infrequent • The rule is stated in FCC/ITU radio operating procedures for limiting test duration in any 5‑minute period

💭 Think About

• Think about why long test transmissions on 2182 kHz or Ch-16 would be a problem for ships in distress • Consider what a ‘brief’ test would realistically look like on a busy distress/calling channel • Ask yourself which option best reflects a very short, momentary test call rather than an extended transmission

✅ Before You Answer

• Verify that the time limit applies to any 5‑minute period, not just once per hour or per watch • Focus on which answer choice would minimize interference with distress traffic • Eliminate any option that seems too long to keep a distress/calling frequency reliably open for emergencies
