How well do the JT modes cope with propagation that spreads the signal
spectrum? This can be over tens of Hz in the worse case.

Even better than JT65 is JT9. A fraction of the bandwidth and according to
the author, about 2 dB better with weak signals. The protocol is the same.
Give it a try, you'll like it.
