What is one characteristic of VHF signals received via auroral backscatter?
Pick an answer to check it.
Answer: B. They are distorted, with a characteristic raspy sound
VHF signals reflected off the aurora sound distorted, with a raspy, buzzing quality. That's because the aurora moves and is irregular, which smears the signal.
Tip: Aurora signals sound raspy and buzzy; CW often works best.
