The Propagation FAQ section addresses common questions about how radio signals travel, why bands behave differently, and what affects signal strength and reliability.
Understanding propagation is essential for effective operating on HF, VHF, and UHF bands.
Common Propagation Questions
- Why Do HF Bands Work Better at Night?
- Why Can’t I Hear Stations That Others Can?
- Does Narrowing Receiver Bandwidth Reduce Noise?
- What Is NVIS and When Should I Use It?
- Why Do Some Bands “Open” and Then Suddenly Close?
- What Is the Difference Between Ground Wave and Skywave?
