🔍 Key Concepts

• MF/HF SSB calling procedures in the GMDSS system • How to avoid interference with ongoing communications on shared frequencies • The difference between selecting a station and checking channel availability before transmitting

💭 Think About

• Before you transmit on any MF/HF working frequency, what must you confirm about that frequency to avoid disrupting existing communications? • Does tuning or testing your transmitter on another frequency help prevent interference on the frequency you intend to use? Why or why not? • Is choosing the closest station or waiting for a traffic list always required, or is there a more basic step that applies to every single call?

✅ Before You Answer

• Verify which option directly prevents interference with ongoing traffic on the intended frequency. • Check which choices are always required versus those that may only apply in certain operational situations. • Eliminate any option that focuses only on range/coverage or later traffic handling rather than the initial act of starting a call.
