[Elecraft] OT: Distinguishable angular momentum in radio photons?

[Don Wilhelm]

The C-band satellite has 2 channels on each frequency - I can't recall 
if one was horizontally polarized and th other vertical or whether one 
used right hand circular and the other left hand.  In any case, it works 
and works quite well.

So having 2 non-interfering non-multiplexed streams on one frequency is 
nothing new.
