Radio Broadcast and Return

The following afternoon.

Although the weather was less than cooperative.

The scattered flurries from the previous night had already turned into a heavy, swirling snowfall.

Whoosh—!

But this was nothing to Evan. With a casual wave of his hand, as though wiping away chalk with an eraser, he cleared off all the leaden clouds covering half of the duchy overhead.

Besides Anita and Livina.

He had also gathered the duchy's wizards, including those from the Tree of Life School, the Mechanical Immortality School, and the Witches, along with the students and professors from Garratt National University's engineering department, on a small hill on Long Island.

Yet it was not until dusk approached, the scheduled time for the test.

That a group of electrical engineers who had already graduated from Garratt National University's engineering department finally completed the final adjustments to the signal transmitter located in Far Sail Territory, sending word that they were ready.

Evan watched the entire process without intervening.

To ensure that the Electrical Age Trend could continue replicating and expanding in the future, it was tolerable to sacrifice a little time for training.

Radio Technology was a technology that transmitted signals through radio waves. Its principle was that changes in the strength of an electric current within a conductor generated radio waves.

Using this phenomenon, information could be loaded onto radio waves through modulation.

When the waves traveled through space and reached the receiving end, the changes in the electromagnetic field caused by the waves generated a current in the conductor. The information could then be extracted from those changes in current through demodulation, thereby achieving the purpose of transmitting information.

This was an extremely practical and important branch of electrical science. Evan, who came from the Information Age, understood even more clearly the power hidden behind
