AMlähetyksissä

AMlähetyksissä refers to AM broadcasting in Finnish. AM stands for Amplitude Modulation, a radio broadcasting technology where the amplitude of the carrier wave is varied in accordance with the signal being transmitted. This method was one of the earliest forms of radio transmission and was widely used for voice and music broadcasting.

In Finland, as in many other countries, AM broadcasting played a significant role in the development of public radio. Early radio stations relied heavily on AM technology to reach audiences. The availability of AM receivers made it possible for a broad segment of the population to access news, entertainment, and cultural programming. AM signals can travel long distances, especially at night, due to ionospheric reflection, which was an advantage for nationwide coverage.

However, AM broadcasting has certain limitations. It is susceptible to interference from electrical noise and other radio signals, which can result in lower audio quality compared to FM (Frequency Modulation) broadcasting. FM technology, which modulates the frequency of the carrier wave, generally offers superior sound fidelity and is less prone to static. Consequently, as FM technology became more prevalent and receivers more affordable, AM broadcasting gradually declined in importance for commercial and public service broadcasting in Finland, with many stations transitioning to FM or digital platforms.

While its prominence has diminished, AM broadcasting still exists in some forms globally, often used for specific purposes like long-range communication or by hobbyists. In Finland, the use of AM for general radio broadcasting is now minimal.
