What is FT8?

What is FT8?

• A. A digital mode capable of low signal-to-noise operation
• B. A wideband FM voice mode
• C. An eight channel multiplex mode for FM repeaters
• D. A digital slow-scan TV mode with forward error correction and automatic color compensation

Answer: (A)

FT8 is a digital communication mode specifically designed for weak signal operation, making it particularly effective for amateur radio operators who need to communicate under conditions of low signal-to-noise ratios. It is part of the WSJT-X software suite developed by Joe Taylor, K1JT, and allows for the exchange of short text messages over radio frequencies, often used in scenarios where conditions are challenging for regular voice communication. The primary strength of FT8 is its ability to decode signals that can barely be heard, which is critical during contests or while using low-power transmissions. The mode employs robust error correction techniques, enabling it to accurately receive data even in noisy environments, thus maximizing the chances of successful communications. While the other options present different modes of operation within amateur radio, they do not capture the essence of FT8. Wideband FM voice, multiplex modes, and slow-scan TV capabilities pertain to different applications and use cases, none of which align with the low signal handling and digital nature of FT8.
