PRINTED IN 1928 IN ORADEA TO INTRODUCE RADIO

        The first radio show in Romania with broadcast content, with the current significance of the term, took place on November 1, 1928.

         In the same time, the construction of a truly professional transmitter was started by Marconi with the financing of the Royal Family of Romania. I did not manage to find any supporting photos, but the press of the time writes that Marconi was in Romania at the installation works.

 

Translating directly from the newspaper page, without corrections:

        The power delivered to the antenna, with the carrier unmodulated, is 150kW feeding into the antenna a radiofrequency current of 106A. The antenna is supported by 2 metal triangular section towers with a height of 253m weighing 140t each, insulated from the ground with 7 cylinders of porcelain. The transmitter had  linear push-pull amplifiers and the modulation was series type with constant voltage.

 

                

                THE BOOK

                                                               

        In the same year appears in Oradea, the city where I live in Romania, a book that grants an entire chapter to introduce the newly appeared radio. Just found in the library of my great-grandmother this book, signed  and dated on the first page.

        Based on the details my great-grandfather built a receiver with crystal detection and then a single tube receiver.   They were the first receivers I played with as a child. There is high probability to found them in the attic of the very old family house. 

 

 

        We can imagine how quiet the medium wave band was at the time of editing the book: the author writes in the page above that he can receive in headphones with the reactive coupling radio and an amplification tube 15-20 transmitters  from neighboring countries, and with the one with three tubes 8- 10 transmitters by  listening in the loudspeaker.
