Which has the MOST effect on the range of a SSB transmission?

Question 1 of 27070

Which has the MOST effect on the range of a SSB transmission?

🔍 Key Concepts

• HF/SSB propagation characteristics (how high-frequency single sideband signals travel) • Effects of ionosphere, time of day, and frequency band on radio range • Difference between radiated power and propagation conditions

💭 Think About

• Think about what primarily controls how far an HF/SSB signal can travel beyond normal line of sight. • Which factor(s) determine whether the signal is reflected/refracted by the ionosphere versus being absorbed? • Among the options, which pair directly relates to predictable changes in HF propagation over a 24‑hour period?

✅ Before You Answer

• Identify which choice mentions frequency band and time of day/night, both critical for ionospheric reflection of HF signals. • Check whether radiated power alone can overcome poor propagation conditions over very long ranges. • Eliminate options that refer to phenomena with little or no real effect on HF/SSB range (e.g., position of the moon or distance from shore).
