7. All features of FT8 DXpedition mode, as in WSJT-X v1.9.1
Enhancements to the FT8 decoder ensure that in most situations
decoding sensitivity is slightly better than for the old protocol.
Symbol rates and occupied bandwidths are the same as before, and
false-decode rates are significantly lower. The decoding threshold
for MSK144 is a fraction of a dB higher than before, owing to the
slightly larger message payload and higher code rate.
Conveying more information in the same bandwidth, using the same
modulation scheme, necessarily means a higher code rate and less
energy per information bit. Nevertheless, the decoding threshold S/N
for the new FT8 is slightly lower than for the old version, because of
improvements in the decoding algorithm. Decoding threshold for MSK144
is a fraction of a dB higher than before. Symbol rates and occupied
bandwidths for both modes are the same as before, and false-decode
rates are significantly lower.
OTHER PROGRAM ENHANCEMENTS: WSJT-X 2.0 has several other new features
and capabilities. The WSPR decoder has significantly better
