The new FT4, FT8, and MSK144 protocols use a different lossless
compression algorithm with features to generate and recognize the
special messages used for contesting and the like. (More to come,
here ...)
The FT4, FT8, and MSK144 protocols use different lossless compression
algorithms with features that generate and recognize special messages
used for contesting and other special purposes. Full details have
been published in QEX, see {ft4_ft8_protocols}.
To be useful on channels with low signal-to-noise ratio, this kind of
lossless message compression requires use of a strong forward error
