When did Guglielmo Marconi begin experimenting with radio waves?

Guglielmo Marconi began his experiments with radio waves in 1894 at his father’s estate near Bologna, Italy.1

During these initial experiments, he utilized relatively simple equipment, including an induction coil to increase voltage, a spark discharger controlled by a Morse key, and a coherer to detect the signals. By systematically improving his apparatus—most notably by incorporating a vertical aerial connected to the ground—he successfully increased his signaling range to approximately 2.4 km (1.5 miles), which convinced him of the practical potential of wireless telegraphy.1
