Oh ****, you got it wrong again!
In Boston, on Christmas Eve of 1906, modulating a spark transmitter,
Reginald Fessenden made a holiday broadcast of a short spoken
introduction, some recorded Christmas music, and played "Oh Holy
Night" on a violin.
Obviously on-off keying was not the ONLY WAY POSSIBLE (your emphasis)
for early ("spark") radio to allow communications.
"Dear Mother Anderson, your son Leonard is failing in practical
applied physics. Perhaps he would benefit from a stint in the Army to
learn a useful trade."
Sunuvagun! Good luck on this one now.
With all kind wishes,
