🔍 Key Concepts

• How different radio frequencies (HF vs VHF vs satellite) travel through the atmosphere and ionosphere • Which systems use HF (high frequency) versus VHF (very high frequency) or satellite bands • Why HF signals often experience fading, static, and ionospheric disturbances

💭 Think About

• Identify which of the listed systems operates in the HF band and which use VHF or satellite frequencies • Think about which frequencies are most affected by skywave/ionospheric propagation and atmospheric noise • Recall which GMDSS systems are most reliable and stable for short-range distress calling near coastlines

✅ Before You Answer

• Verify which option(s) use HF (3–30 MHz) radio waves • Verify which option(s) use VHF (around 156–174 MHz) line-of-sight communications • Consider which system depends most on the ionosphere for propagation, making it vulnerable to fading and static
