Program: FT8: How Does It Work? - David Grybos, KK6US

Or: “Wow, this is State-of-the-Art Stuff!”

This high-level presentation will hopefully provide a: “Oh! That’s how it works” insight as to how FT8 works and how it provides the performance we enjoy. You won’t be Digital Communications experts and there won’t be any mathematics.

The talk will cover: Overview; User Messages; Source Encoding/Decoding; Forward Error Correction (FEC); Modulation; Synchronization; Demodulation

Hopefully you will have an appreciation of how State-of-the-Art FT8 is.

Questions, discussion and additional input from club members is solicited.
