Marking the 100th anniversary of the first radio transmission in Chile, the Museum of Science and Technology has presented an artistic sample of the various radio components of the past decades. Added to this is the revival of the first project carried out in 1922 by Enrique Sazi and Arturo Salazar, in the hall of the El Mercurio newspaper building.
Radio joined the experiment and broadcast in this form from the Museum of Science and Technology. On the topic, we spoke with researchers Renato Minares and Francisco Garrido. Both are responsible for the wireless technical sample.
Check out the interview with Renato Minares and Francisco Garrido.
broadcast century
Renato Minares is a collector of radios, his passion for restoring them has made him look for different parts from different years, and a large part of his collection is displayed in the museum. “We discussed that we could make a replica of the first radio transmission with components of that time. We are making an AM transmission system.”
He further added: “I’ve been a collector for over 60 years, passing by Persian galleries in search of old radios and recordings, I have very few of these”.
Francisco Garrido, for his part, points out the characteristics of these radial pieces. “The hardware that powers this transmission is outdated, we basically have one from 1997 and the most recent one running from 1942.”
“The idea is for it to be a real transmitter, reproducing the style of Enrique Sazi and Arturo Salazar, because they didn’t have any recipe for how to make a transmitter, they were experimenting, doing experiments”confirmed.
Radio Evolution
Regarding technological progress and the evolution of the radio medium, Garrido points out that: “From 1940 the first FM transmitters began to operate in the United States, which is a drastic change because it generates better quality than AM with less interference and noise.”
He added, “The quality of the microphones has been improved and the sound has been made clearer. Today it is not so clear because technology has changed a lot, what is AM radio is not heard much.
Another method of transmission over longer distances using satellites and waves has been improving. It was in the 1920s that the first radio standards emerged and allowed each station to have a fixed frequency and not interfere with each other. This gives an order regarding the huge radio broadcast,” he closed.
