[THEME: Amateur radio}
The not-so-secret word for today is BROADCAST.
|People have long enjoyed listening to the radio.|
When you turn on your car radio, there's no telling what you might hear. Could be your favorite song, and you might sing along. Or maybe it'll be a talk show host, in which case, you might be inclined to argue (i.e. scream) an opposing point of view. One thing those seemingly different scenarios have in common is this: both are one-way transmissions. No matter how delightfully you harmonize, or how brilliant your rebuttal for the blowhard, the voices coming out of that radio can't hear you.
That is broadcast radio.
One thing amateur radio operators do NOT do is broadcast.
With amateur radio, I can certainly listen passively to other operators, but for me, the real joy lies in active participation. When a properly licensed amateur radio operator hears a voice or Morse code signal coming out of his speaker, he can
|Reach for a microphone ...|
|Or key ...|
So, there ya have it. Commercial radio stations broadcast. But we hams ... we communicate.
