As one gets older, one can't quite remember how long ago something
happened, but I seem to think some ten-twenty years ago, there was a
group of hams who uplinked to the band edges of the C band satellite
birds, I think using SSB. The down link range of the C band birds is
3700-4200 MHz, with the uplink range of 5.925-6.425 GHz. With the
amateur band being 5650 to 5925 MHz, one can see how a signal at 5924.9
would probably still make it through the bandpass filters on the bird.
Of course, RF would have to be, um, azimuth and elevation "directed"
Interesting story, I wonder if anyone,"who knows more (!)", could fill
