In 1973, the Federal Electrical Commission in Mexico City was involved in the production of a television program for Canal 4 (Channel 4) designed to highlight Nikola Tesla’s sound experiments with turbines and wireless resonant electric circuits. This initiative was named “Visible Sound.” Ultimately, due to concerns regarding low viewership, the decision was made not to air the show. Since then, it has been classified as “Lost Media,” archived within annals of the now-defunct Canal 4 in Mexico City. During the sound experiments, members of the Commission employed early synthesizers and circuit boards to capture and manipulate the vibrations produced by these devices.

Fast forward to 2024, Telekinett successfully obtained these important recordings, which had been preserved on magnetic tape by a former employee who had worked on their optimization and mastering (Mr. “________________” wishes to remain anonymous.)  These recordings have since been creatively repurposed by Mauricio Reyes and Carl Michael von Hausswolff, resulting in an impressive project titled “VISIBLE SOUND: Nikola Tesla’s Mattergy.”

XHTV holds the distinction of being the inaugural television station in Mexico and served as a foundational element of Telesistema Mexicano, which evolved into Televisa in 1973.

In 1949, Romulo O’Farril was awarded the concession for XHTV, which was allocated to Televisora de México S.A., a company owned by Novedades, O’Farril’s established newspaper. The station began receiving its equipment in March 1950, culminating with the arrival of a mobile studio in July of the same year.

Mr. “________________” served as a sound engineer at Channel 4 in Mexico City in 1973, where he was tasked with capturing, mixing, and reproducing sound through electronic audio equipment. His expertise spanned a wide range of applications, including music, television, film, and various other media platforms.

As a principal audio engineer, he had the chance to operate in various settings and engage with a wide range of artists and clients.

A Tesla coil is an electrical resonant transformer circuit that was developed by inventor Nikola Tesla in 1891. This device is designed to generate high-voltage, low-current, high-frequency alternating current electricity. Tesla explored various configurations that typically involved two or three coupled resonant electric circuits.

These circuits facilitated Tesla’s groundbreaking experiments in areas such as electrical lighting, phosphorescence, X-ray production, acoustic research, high-frequency alternating current phenomena, electrotherapy, and the wireless transmission of electrical energy.

Commercially, Tesla coil circuits were utilized in spark-gap radio transmitters for wireless telegraphy until the 1920s, as well as in medical devices like electrotherapy and violet ray apparatus. In contemporary times, their primary applications are in entertainment and educational demonstrations, although smaller coils continue to serve as leak detectors in high-vacuum systems.

Initially, Tesla coils employed fixed or rotary spark gaps to intermittently excite the resonant circuit; however, modern implementations often utilize electronic devices to achieve the necessary switching functions.
