README 

Minimal set of files required to build the FT8 decoder by Joe Taylor, K1JT.

The original sources can be found at:

  https://sourceforge.net/p/wsjt/wsjt/HEAD/tree/branches/wsjtx/lib/ft8

A brief description of the FT8 protocol can be found at:

  http://physics.princeton.edu/pulsar/k1jt/ft8.txt

Changes from the original sources:
  - ft8d.f90 is updated and working
  - crc10.cpp and crc12.cpp are replaced with crc10.c and crc12.c
  - hardcoded values are replaced with parameters in baseline.f90 and ft8b.f90
  - input format is changed to complex samples at 4000 samples per second
