>Don't you also get a lot of multi-path problems at 56kb?

Yes, and the higher in frequency you go, the worse it gets.

Pretty soon, the multipath isn't just blurring the bits, it's shifting
them, and you lose.  The only solution appears to be spread-spectrum.

Even at 6m (with an STA it's legal), 56kb MSK is haunted by multipath.
It works, but it's far from ideal.
