Morphology
radiotelegraphy = telegraphy (transparent) = radio + telegraph + y
The word denotes telegraphy performed by radio—combining 'radio' with the existing noun 'telegraphy' yields the stated meaning directly.
Etymology
Radiotelegraphy is made of radio and telegraphy, where tele- means 'far' and graph means 'write', so telegraphy is sending written messages over a long distance. Adding radio, which points to using radio 'waves' to carry the signal, gives a word that means sending telegrams by radio, like Morse code, instead of by wire.
