The very first radio transmission was made in 1900 by the  Swedish navy as they borrowed a Marconi radio from AEG in Germany. However, this was a military operation, and they used morse code. This was done near Stockholm and was Sweden's first radio transmission ever.

In Goteborg, Uno Särnmark was the first to be on the air, As lack of historical documents and proof we assume the Uno Särnmark performed his transmission from a technical view of point. He did not send any music or entertainment as we know of today. Unverified information is that Uno Särnmark had his first transmission year 1922.
Uno stopped his transmissions when KG Eliasson started with his first transmission on January the 4th 1924. After that KG Eliasson made almost one transmission every day occurred for testing and optimizing his transmitter for the big premiere transmission on January the 15th 1924.

There is very little documents about Uno, however KG Eliasson's personality was to document everything he did.

As a bonus, KG Eliasson was also the first one to entertain the Swedish people by sending life from Stora teatern (The opera house in Göteborg) on 5 March 1924. The opera name was Tiggarstudenten.
Later on, KG Eliasson was one of the founders of the radio club Göteborgs Sändareamatörer (www.sk6gsa.se), also Swedens oldest radio club since 1923.

Sveriges Riksradio starts a few years later, in 1927, with broadcasts on long wave via Motala.

On 10 December 1939, Radio Sweden starts broadcasting in foreign languages (English, German, and French) on medium and short wave.

In September 1940 and following German orders, all Swedish stations sign off at 2300 so that British pilots cannot use them for navigation.

On 30 November 1991 The longwave transmitter of Sveriges Riksradio in Motala (189 kHz) is switched off.

On 23 October 1996 the long wave station at Grinatol does a special 30 minute broadcast on 17 kHz in morse code (CW). This station broadcasts without the use of valves or solid state devices. The frequency is generted by an alternator such as the one in a car, but a thousand times bigger. The power is hundreds of kilowatts.

On 15 January 2004 the old Swedish frequency of 981 kHz is used today only for a commemorate broadcast on Swedish radio pioneer K.G. Eliasson (see also 1924). The name of the station was SMZX (Eliasson's ham call sign).

On 27 March 2005 Radio Nederland starts relaying via Sölvesborg (1179 kHz). This relay ceases on 31 October.

On 30 October 2010 Radio Sweden ceases all medium and short wave broadcasts.
