If you want to transmit "logic zero", blow on a police whistle. It emits a sound whose frequency is 1800 cycles per second.
If you want to transmit "logic one", blow an air horn like this one. It emits a sound whose frequency is 750 cycles per second.
Now you have a way to embed information into frequency. First convert the information into binary digital data. Then blast out the information (zeroes and ones) using a police whistle and an air horn.
