The excitement of using the JT65 program on HF is NOT for those signals you
can clearly hear and probably operate with another mode, but for those times
that the propagation shows not to be there, you dont hear anything but
possibly a slight raise in static on a band, etc. Then you can put this
mode up, leave it alone, and see what pops out. Its for "playing" not
really trying to communicate. FYI if anyone in P5 wants to work it, plse
do so. Whether we can hear you or not, we will be there.
