As much as I respect the “old way” of ham radio, I’m continually amazed at the new developments, and just plain interesting things people come up with.

Australian ham VK2DJG posted about Aircraft Enhanced SSB: bouncing VHF radio signals off of airplanes. It’s sort of like the way most long-distance ham contacts are made, via sky waves, except that they’re reflecting their signals not off of the ionosphere, but off of airplanes. It looks like they’ve had good success with the mode, too.
