KortvågsS

KortvågsS refers to shortwave radio transmissions that originate from Sweden. Shortwave radio operates on frequencies between 3 and 30 megahertz, allowing signals to travel long distances by bouncing off the ionosphere. This makes it a suitable medium for international broadcasting.

Historically, Swedish radio organizations, such as Sveriges Radio, utilized shortwave to reach listeners outside of Sweden, particularly during times when other communication methods were limited. These broadcasts could include news, cultural programs, and music aimed at Swedish expatriates and international audiences interested in Sweden.

The use of shortwave broadcasting has declined significantly with the rise of the internet and satellite technology, which offer more efficient and widespread communication channels. While international shortwave broadcasting from many countries, including Sweden, has largely ceased or been greatly reduced, the technology and the historical role of shortwave in international communication remain a part of radio history. The term "kortvågsS" specifically points to these transmissions with a Swedish origin.
