FST4W - jt9 - to .wav or to .c2 #1082

Closed waterwin closed 1 year ago

Picking up from this very informative (closed) issue : Conversion of WSPR decoder to FT8 #689 The final solution here was to have a decoder using .c2 files instead of .wav files

I intend to study a jt9 implementation to do decoding of the new (well, newer than FT8) FST4W mode. Reason is the improved performance, even on the higher bands, of this mode compared to WSPR. See the wsprdaemon postings. Also, the FST4 and FST4W decoder has a tool to measure estimated Doppler spreading on successful decodes, which gives very interesting information for the study of propagation.

jt9 does not accept .c2 files, so a direct use of the existing FT8-multiband decoder appears to be a no go.

To be continued. Suggestions are very welcome (even though this is of course not an issue) Erwin
