Rohde & Schwarz EK-070 For decades, short-wave communication was the only way to communicate across long distances without telephone wires. With the appropriate equipment and antennas, even global communication was also possible. In those days, the use of jamming transmitters to block an unwanted foreign station was the same as todays network blocking.

The older commercial receivers can be found in the section „Boatanchors“, modern solid state sets in this section.

With the advent of satellite and internet communication, shortwave communication has largely become obsolete in Europe; in other continents with poor infrastructure and as a „stopgap“ for disaster situations, shortwave communication and the radio amateurs who can make use of these waves with their equipment are still occasionally used.
