When a watch is required on 2182 kHz, at how many minutes past the hour must a 3 minute silent period be observed?

Explanation:
On 2182 kHz the watchkeeping rule includes a 3-minute silent period that occurs twice every hour. These silent windows begin at the top of the hour and again at the 30-minute mark, giving listening-only intervals from 00:00–00:03 and 00:30–00:33 of each hour. The purpose is to provide uninterrupted time to listen for distress calls and other essential traffic, ensuring the frequency remains clear for emergency communication. Therefore, the silent period must be observed at 00 and 30 minutes past the hour.
