Answer Options
- A) A wideband FM voice mode
- B) A digital mode capable of low signal-to-noise operation
- C) An eight channel multiplex mode for FM repeaters
- D) A digital slow-scan TV mode with forward error correction and automatic color compensation
Correct Answer: B
Explanation
FT8 is a modern, highly specialized digital communications mode created by Nobel laureate Joe Taylor, \text{K}1\text{JT}, and his team. Its key feature is its ability to communicate when the signal is buried far below the noise floor, which is essential for weak signal work.
FT8 is a digital mode capable of low signal-to-noise operation due to its fast, standardized message structure and powerful error correction algorithms. Contacts are automated and short, typically lasting only a few seconds, making it ideal for confirming contacts during poor propagation or with very low power.
