The advent of radio in the early 1900s brought about radiotelegraphy and other forms of wireless telegraphy. en.wikipedia.org

The origins of this are from the era before radiotelegraphy and radiotelephony, when orders were given by flag signals. en.wikipedia.org

Continuous-wave radio was called radiotelegraphy because like the telegraph, it worked by means of a simple switch to transmit Morse code. en.wikipedia.org

The licence allows a user to make radiotelegraphy and radiotelephony transmission in 13 frequency bands. en.wikipedia.org

It is used in spoken word (radiotelephony) morse code (radiotelegraphy) and in various digital modes. en.wikipedia.org

Signals can be sent by flaghoist, signal lamp (blinker), flag semaphore, radiotelegraphy, and radiotelephony. en.wikipedia.org
