    1. In this case, every message you send will look the same. The person receiving your message will not know how to decode it, since you never did anything to differentiate one letter from another.

      This is the semaphore analogy and it's about making signals with flags. If all the letters looked the same you couldn't make out any words. Same with radio waves, if all the waves were just simple sine waves your antenna wouldn't be able to detected the right information for that specific dial. So radio stations use Modulation to change the shape of the waves.
