🔍 Key Concepts

• International silent periods for distress and safety traffic on MF (medium frequency) bands • The specific frequency range 500 kHz and surrounding guard band uses • Distinction between routine traffic vs. distress and safety traffic

💭 Think About

• Think about what special protection is given to the traditional 500 kHz distress frequency and nearby channels. • Ask yourself whether routine communications are always banned on this band, or only banned at certain scheduled times. • Consider how international silent periods are designed to keep a frequency clear for listening—what impact does that have on routine traffic?

✅ Before You Answer

• Verify how the international silent period is defined in relation to 500 kHz and the 480–515 kHz band. • Check whether the band 480–515 kHz is part of the maritime MF distress and calling band or if it lies outside the marine bands. • Confirm if routine transmissions are restricted only during silent periods or at all times on these frequencies.
