c75c4aefda Further improvements to JT9 decoder. 
Better AFC (wider range of possible drifts; more accurate DT alignment).
Better definition of metric tables used by Fano decoder.
Zero-centeres soft symbols, instead of offset +128.
Tuned several empirical parameters.

010f85ec70 Further algorithmic tweaks in the JT9 decoder. 
More detailed message to come, with comparative timing statistics.

9890731f4f 1. De-activate submodes JT9-5, JT9-10, and JT9-30. (This makes the shared 
memory region smaller by some 150 MB.)
2. Some code cleanup (removing unused lstrong, etc.)...

7cb0731dc6 Reduce ntol. 
Add "red3" (but not yet using it).

057287fab1 Many changes to the procedures for selecting decodable candidate JT9 signals. 
This code may be the new benchmark?

bd103459f1 Added routine "chkss2" to test sync vector for sanity before attenpting 
Fano decode.

f1d6248c46 Temporary code, to aid with a series of tests of the JT9 decoder. 
This commit will serve as a benchmark for comparison with new code to
be written.
