In Romania, the first wireless telegraph equipment, imported from France in 1903, was installed on the sea ships: Regele Carol I , Principesa Maria , Împăratul Traian , Dacia , România and at the headquarters of the Romanian Navy Service in Constanța. The station of S.M.R. acted throughout 600 km ensuring the communication with the ships on the sea [1]. The land army was equipped in 1908 with mobile stations from Germany (three devices with sparks, type Telefunken ) and in 1913 with stations of low power from England (produced by Marconi Company). The equipment was inappropriate so that when Romania entered World War I, the army did not own any device of high power, which could enable the communication at distances of more than 1000 km [2]. Under these circumstances, eng. Emil Giurgea made available his own station built with components brought from abroad (1914), while prof. Nicolae Vasilescu-Karpen (1870-1964) created a wireless telegraph station in Park Băneasa (1915). It was also in 1915 that prof. Nicolae Vasilescu-Karpen installed in Bucharest (Herăstrău), a radiotelegraph station imported from France, of a power of 150 kW and the wave length of 11000 m, replaced five years later with a broadcasting station with electric arc [3].
Radiophony in Romania undertook a difficult road not because of lack of interest to this field of activity, but mainly due to a lower rhythm of legislative activity. Scientists and scholars sustained in various publications and conferences the necessity of introducing radiophony in Romania too, taking into account that in many European states and in the U.S.A. there were permanent radio emissions already in 1919-1920. Their activity resulted in the foundation, in 1925, of the "Association of the Friends of Radiophony", under the coordination of prof. Dragomir Hurmuzescu (1865-1954). The association had as an objective to make radiophony popular by public auditions, conferences and training courses, which took place on Victor Emanuel Street in Bucharest [4]. It was also prof. Dragomir Hurmuzescu who coordinated experimental broadcasts at the Polytechnical Institute of the University of Bucharest.
Magazines, specialized or addressing to the large public, such as Radiofonia și Radio-Român (Fig.1), also played an important role in the popularization of radiophony. The bimonthly magazine Radiofonia issued on 15 October 1925, within the auspices of the Association of the Friends of Radiophony, had an editing team which included professors and prestigious engineers such as: prof. Dragomir Hurmuzescu, eng. E. Petrașcu, eng. Mihai Konteschveller- inventor and author of specialized books, eng. I. Constantinescu-author of taught courses in telecommunications for student, among others. In 1928, the magazine is re-published as a promotional organism of the Radiotelephonic Broadcasting Society of Romania.
