Default parameter settings for JT65 decoding set for HF conditions.

Browse Source 
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.
