[SFDXA] [DCARC] FT4 In Use!

[Kai]

Pete and All,
Quoted from Joe Taylor...
"FT4 is mostly like FT8, but is 2.5 x faster, uses 1.8 x the bandwidth,
and is 4.6 dB less sensitive. Many other details are summarized in
"The FT4 Protocol for Digital Contesting", available here:
http://physics.princeton.edu/pulsar/k1jt/FT4_Protocol.pdf "

Furthermore, the developers specifically say that it will not be used
for the 2019 Field Day.

Cheers
Kai, KE4PT
