Why Morse code is still in use?
Despite the capability of voice communication, Morse code is still in use. One important reason is that a vast group of the radio amateurs still adore Morse code. A ham radio operator employing digital communication techniques (like Packet Radio, Radio Tele Typing-RTTY or Amateur Tele-printing Over Radio-AMTOR) in his ham radio operation treats Morse code with much the same affection he has for those modern innovations. A ham radio operator wearing his headphone and the Morse Key in hand can send message silently without disturbing family members who are in sleep! Another reason is that short wave radio telephone (voice) signals often suffer very rapid and deep fading; two frequencies separated by only a few hertz, fade at different times. To overcome this, modulated code tones are transmitted. The situation is now that under severe conditions of fading, the carrier frequency may fade out completely but one or the other side band may remain strong as a result a continuously readable si
