🔍 Key Concepts

• SSB (Single Sideband) on MF/HF frequencies and how they use the ionosphere • Day vs. night changes in the ionosphere (D-layer absorption vs. F-layer reflection) • Effect of solar radiation and darkness on radio-wave skip distance and range

💭 Think About

• Think about whether radio waves go farther when they are absorbed more or when they are reflected more by the ionosphere. • When is the ionospheric D-layer strongest: in bright sunlight, around noon, or in full darkness? How does that affect long-distance HF communication? • For long-range SSB, are you usually trying to use ground-wave only, or are you trying to take advantage of sky-wave (skip) propagation?

✅ Before You Answer

• Identify which times of day in the choices are most strongly affected by sunlight vs. darkness. • Recall when D-layer absorption of MF/HF is highest (hurts range) and when it weakens (helps range). • Confirm that you’re thinking about longest range via sky-wave, not just local ground-wave coverage.
