Work is in progress (possibly taking forever) to explore decoding options. On a fast 32-bit microcontroller decoding might be possible, perhaps with some tradeoffs.
# What works
So far only encoding is implemented. It should support the basic set of FT8 messages:
* CQ <call> <grid>, e.g. CQ CA0LL GG77
* CQ <xy> <call> <grid>, e.g. CQ JA CA0LL GG77
* <call> <call> <report>, e.g. CA0LL OT7ER R-07
* <call> <call> 73/RRR/RR73, e.g. OT7ER CA0LL 73
# What doesn't
* Encoding free-text messages
* Encoding contest mode messages
* Encoding compound callsigns with country prefixes and mode suffixes
* Decoding
# References and credits
Thanks to Robert Morris, AB1HL, whose Python code (https://github.com/rtmrtmrtmrtm/weakmon) inspired this and helped to test various parts of the code.
This would not of course be possible without the original WSJT-X code, which is mostly written in Fortran (http://physics.princeton.edu/pulsar/K1JT/wsjtx.html). I believe that is the only 'documentation' of the FT8 protocol available, and the source code was used as such in this project.
