Three new options appear on the Decode->JT65 menu:
"Fast", "Normal", and "Exhaustive". The program is most sensitive
if you choose "Exhaustive". Choosing "Normal" will make decoding
slightly less sensitive, but the loss is not great, and decoding
can be twice as fast. The "Fast" setting is faster still, but can
be less sensitive by 2 dB or more in some cases. If you have a 1.5
GHz or faster computer, use "Exhaustive". With a slower computer
you may want to experiment with the other settings.
