e25dd201a3 Experimental changes to JT65 decoder:
1. Change to rectangular FFT window for 2D sync spectrum (ss).
2. Move 2D sync spectrum array to common block.
3. Change to quarter-symbol steps for the ss array.
4. Allow up to 4 decoding passes.
5. Wire up Fast/Normal/Deep for 2, 3, or 4 decoding passes.
6. Make minsmo=0 (instead of 1) for minimally spread JT65B/C signals.

0e15a4cd5c Default parameter settings for JT65 decoding set for HF conditions.
More aggressive parameters are selected with higher values of 
"Aggressive decoding level" on the "Advanced" tab.  With settings
greater than 0, be sure to set Ftol=1000 if you want to decode over 
the whole passband.

the Fortran routines.

d7e7b43045 Many changes to the JT65 decode chain. This is development code! It
includes an initial implementation of the FTRSD decoder with a "qual"
parameter for evaluation of candidate codewords.  Also includes hinted
decoding.  Further testing is needed.
