Thanks Chip. FYI... I neither called nor labeled myself as the inventor.



FT8Call is a derivative of the WSJT-X application, restructured and redesigned for keyboard-to-keyboard message passing, similar to PSK/FSQ/Olivia/etc. It uses FT8 modulation as the transport. But, it does not use FT8 encoding for the delivery of the text. That part is original. It is a variable encoding and packing scheme to allow greater than 13 characters per transmission cycle (up to 23 actually).



You can read more about that in the document linked above.
