Apollo 11 Mission

On July 20, 1969 while we were glued to our TV sets, Jack Yanosov and his co-workers at RCA in Camden, NJ, were monitoring the NASA circuits to see if all of their radios and electronics were working properly. The excitement rose at 02:51:16 UTC, when the hatch was opened and the 'actual' first words transmitted from Neil Armstrong's backpack radio were, "OK Houston, I'm on the porch." And a few seconds later at 02:56:15 UTC, as his feet reached the surface, Armstrong said those memorable words, "That's one small step for man, one giant leap for mankind." And a cheer went up in Camden, and around the world.

Those words, "One small step," were sent by via VHF radio using Amplitude Modulation with a radio that was designed by a ham.
