When the Kšnigsbergradio came to the farm.



Svenn Martinsen


If you come to NorwayÕs capital city Oslo, and take the subway line no.2 going eastwards to EllingsrudŒsen, and then go off at Tveita station, youÕll be in the middle of a large suburban center, typical of many European countries.


Most of the large number of people going through the mall every day wonÕt have the slightest idea that just behind the centre, a very strange radio station was operated by the German Occupation Forces during the Second World War.


It was one of 23 mobile German broadcast stations spread across Europe, 22 in trucks and 1 in a train. The station we are dealing with in this essay was called Sender L or Transmitter L.[2] Previously it was used in Rovaniemi in Finland, operating as Laplandsender.


Even if the station seems to have been mothballed after the Nazi regime was conquered and peace came to the European War Theatre, it was in existence all of summer 1945, and a smiling German Military Station Manager even proudly received foreign journalists pointing machine guns at them!


This then is what is known from several sources so far of the story of the Kšnigsbergradio at Tveten farm.


Source 1. A Crystal receiver in the loft. FromÓGroruddalsungdom i krigstidÓ, p.109.[3] By kind permission from the author: Bj¿rn H. Syversen, Groruddalen historielag.


Karl-Henrik Amundsen, a former employŽe of Telenor has told about a German-controlled radio station operating in Oslo, Norway possibly from as early as 1942, when he was 15 years old.


This was not identical to the regular Oslo LKO Longwave station at nearby Lambertseter, operating on 260 kHz, also in German(ÓDer Osloer senderÓ) and Nazi Government hands at the time. The site was heavily guarded, and also had been equipped with jamming equipment.


The source received the transmissions on a self-built crystal receiver well hidden in the loft at his home in the village of Godlia. The propaganda transmissions were both in Norwegian and German, but mostly with a lot of dance music. The station identified as Radio Norden or similar.



Picture: Radio listening in the bunker. Typical German radio set for use in the field. Note the dial markers for German stations like the Kšnigsbergradio. This set was found in the Siegfried bunker in Bud.


The Godlia source also says that the German occupation forces established a Medium Wave broadcasting station at a field belonging to Tveten farm. Behind one of the large Tveita blocks today, there still is a large hill, that local people think may hide the remnants of a bunker, containing most of the installation. Visible were the three 60 metres custom-built wooden antenna masts, each wrapped with additional planks painted with two red and two white fields also having an inside ladder. Local kids dared to climb to the top after the Germans had left. As far as Mr.Amundsen can remember, the guy wires were cut and the towers felled relatively soon after Norway regained her freedom in May 1945. I do not know who did this, Milorg(The Resistance) or others, he added.


Incidentially, at this time, there were largely open fields between the radio station and GodliaÕs Stordam Road. A maid, living in one of the houses there, had a terrible experience late one night. She was abruptly awakened by a shot, and saw there was a bullet hole in the window. It emerged the Germans had a party[4], and drunken as they were, had their fun by firing shots in every direction. The bullet was later found in the girlÕs room.



Picture: Note the anti-Semitic tone in this typical ÓHave a think about itÓ poster issued by the NorwayÕs Quisling fascist government during WW2 warning against listening to the BBC.


Comment: Norwegians could not listen to the radio at this time without risking their freedom, and most radios had been confiscated since 1941. There were however, quite many illegal listeners, including publishers of illegal papers often listening to the news from ÓLondon RadioÓ(BBC in Norwegian).

Comment: Shortwave transmissions with the title ÓFrohe Musik nach Mitternacht auf kurzer WelleÓ are documented in February 1944.[6]


Source 3. Ršster i Radio Winter 1943.


ÓJust before the New Year a new Soldatensender appeared on Short-and Longwaves. The Longwave station is not too strong in Stockholm, but has a very good signal into Norrbotten. The shortwave signals on 25,4 and 45,5 metres are well heard in Stockholm, but are not logged in Northern Sweden so far.


Programming is light, and consists of gramophone jazz, ouvertures, musical potpourris, radio drama, as well as re-transmissions of Deutschlandsender and the Wehrmachtbericht. One is not sure of the location of this sender, but it might be in Troms¿, Bod¿, Vads¿ or elsewhere in Northern Norway.Ó

From MV-DXingens historia: MV-DXingens historia fram till 1950-talet:


ÓSwedish listeners were towards the end of 1943 able to receive a new Longwave station on 1010 metres calling itself Soldatensender Lappland. In the county of Norrbotten the reception quality was good, but it also used some Short Wave transmitters that were possible to hear from more Southern locations. It targetted German soldiers stationed in Norway and Finland. It broadcast a lot of gramophone records, but also re-transmitted Deutschlandsender in Berlin as well as the inevitable Wehrmachtbericht, the war news.ÓÉ


From MV-DXingens historia: Andra vŠrldskrigets slut:


ÓHier spricht der KšnigsbergsradioÓ/

HŠr talar Kšnigsbergsradion


Another example of the will to fight is what happened to the Swedish programs transmitted from Kšnigsberg in East Prussia, today known as the Russian enclave of Kaliningrad, on 868 and 224 kHz.[7]



When the Soviet Army captured the city, a substitute to this station suddenly surfaced at the end of April 1945, when everything was quite hopeless for the Germans. Now, however, the station was heard from Norway, on 1010 metres longwave. In the last shaky minutes of the war a station somewhere in Eastern Norway had been established, complete with the Swedish editorial staff from Kšnigsberg. I heard it myself several times around April 25, as a newspaper article of April 23rd had informed that the station had been on the air for some days.Ó


Comment: The Wavelength table of R¿ster i Radio  for March 26th, 1944 has a listing of Rovaniemi on 1220 metres, 246 kHz. This was the domestic Finnish service. Their station in Rovaniemi opened September 19th, 1943.[8]

Picture: The actual newspaper article relating about Yngve Hugo detecting the ÓnewÓ Kšnigsberg.


ÓThe Germans have re-activated the Swedish-language programs on the radio, mainly with the same personnel that took care of the Kšnigsberg programs.


On RadiotjŠnst-where by the way chief director Yngve Hugo discovered the new transmitter- a direction finder has been used and the station is considered to be situated 265 degrees westwards from Stockholm, which should account for it being in Southern Norway, maybe Kristiansand.


A female speaker, whose voice was identified as one of the Kšnigsberg voices, announced a large concert. At 2215 hours there was a Swedish news bulletin. The entire program was in the old Kšnigsberg style[9], with two male speakers, also recognized from the Kšnigsberg voices.


The news bulletin mentioned GoebbelsÕ Saturday speech and mentioned Berlin as a front city and the target of the Red Army. The transmission was noted for its anti-Russian propaganda. The station transmits on the wavelength of 1010 metres and the call sign is ÓHallo Norden.Ó The news bulletin was later suddenly abrupted, and dance music continued, without there being further announcements.Ó

In Ršster i Radio July 29th, 1945 there was large coverage on the ÓNorwegianÓ Kšnigsbergradio. The explanation of how Kšnigsbergsradion as it was known in Swedish might be able to come back from Norway was now given. The journalist had gained approval to visit the site, and he was consequently let through the barbed wire while a machine gun was pointing at him.





Picture from Ršster i Radio July 29th, 1945. Giant station on wheels. Propaganda station revealed.


ÓA 20 kilowatt mobile radiostation had been placed on a hill outside of Oslo, in 6 Mercedes 6-ton trucks complete with necessary equipment and a telescopic aerial being 46 metres high. When it was in operation, the cars would park side by side, and a gangway with ÓaccordeonÓ tarpaulin walls put up between each unit. One unit had a studio, as automated as possible, in order that amateurs might operate it if necessary. The transmitter mast was placed on the last car in the row. In addition a 13-ton car and six utility cars, with a workshop, etc. The station, only being able to use longwaves between 600 and 2000 metres, was possible to erect and be on the air after 2 1/2 hours. Frequency changes were done in 2 1/2 minutes.Ó



Picture from Ršster i Radio July 29th, 1945.

The German Officer who proudly showed the station to the RiR-journalist indicated it had cost 2 1/2 Million Reichsmark. Goebbels was the information genius of Hitler and even that early prepared the propaganda offensive necessary for the coming German expansion. He also said that the Germans had six larger mobile transmitters as well as twelve ligther ones for Medium Waves. It was said that they also had 100 kW-transmitters in railway wagons.

When the Swedish journalist asked why the transmitters had been built already 1937, the Lieutnant replied that it was for transmissions from Parteitagen and Óother strange happenings in the countryÓ.

ÓI am sure you didnÕt need so many transmitters for this use? WasnÕt it rather an unit for defence purposes?Ó Then the Lieutnant laughed.Ó


The proud station caretaker also said the station had not only been used in Rovaniemi as ÓSoldatensender LapplandÓ, but before that on an island off the Dutch Coast!Ó


Comment: The photo coverage of Ršster i Radio from July 29th, 1945 shows more radio masts than the one that belonged to the Rovaniemi equipment according to a drawing in the same magazine.[10]

ÓIn 1942, a mobile radio station, housed in 7 seven railway vans, was taken to Rovianemi (ROE-vee-AH-na-mee) in Finland where it was placed on air from the German army barracks 10 kms out of town. This army entertainment station was on the air for nearly three years.


The daily schedule from Laplandsender consisted of variety programming, news bulletins, and Finnish language lessons. The final broadcast from this unit was in November 1944.


When German forces withdrew from Finland to Norway, they took their mobile radio station with them. However, after a further withdrawal, the station was abandoned and it is now on display in the Radio Museum in Bergen, Norway.Ó

Ó1945-1948:  20 kW German mobile field station, that came from Finland, captured by Norwegian Forces after the war. Consisted of mobile units driven near each other with a roof added.  If the Montreux Plan had been activated, Vigra would have used 708 kHz. However, it was logged in Sweden on 629 kHz in October 1945. (R¿ster i Radio 43/45)But Longwave 282 kHz is mentioned in list from 1946, this also being the frequency late 1945.[13] 1947: 629 kHz 20 kW.  (This is the frequency from the Copenhagen Plan not officially implemented before March 15th, 1950!)

ÓÉAfter the war the reserve transmitter of 1 KW, was substituted by a 20 kW mobile broadcast station taken over by the Germans. The booty, originally from Finland, consisted of several mobile units that were linked and a roof was built over them.

In this book, what was Sender ÓLÓ is dealt with under the subject of reserve transmitters after the war. No mention is made of any appearance at LKA Vigra or LKB Bergen. The complete station was mothballed in a garage at Nordseter, Lillehammer. The Telegrafverket(later: Televerket, Telenor) took it for granted than they owned it. In 1949, 3 of the trucks, including the one with the temporary antenna, were sold on the civilian market. An inspection was held the next year, and established that 6 of the units, including the transmitter and permanent antenna were intact. In addition, a diesel generator truck was found at Raufoss, with considerable damage.


A lot of discussion followed regarding ownership, use and responsibility, and it was not before 1954 that the Defence Staff decided the station to be given to the NRK complete and cost free.


Then it was up to the NRK to continue the discussions. Some of the ideas for use that came up were reserve for LKO Lambertseter 218 kHz(later at Kl¿fta) or as a new relay for the NRK at Andoeya in Northern Norway.


It would appear that nothing at all came out of this, and what was the 2,5 Million Mark Sender ÓLÓ , now at LKF in Fredrikstad, was scrapped in the early 60s.


Comment: The story is not unlike what happened to 200 kW LKO Kl¿fta 216 kHz where the two towers were felled 1995, or the sad fate of most of the Decca station sites from 1998 onwards. It would seem that many decision makers cannot have had a clear understanding of the potential of AM broadcasting, and what it could mean for the country.

Final comment: HitlerÕs Airwaves


The book HitlerÕs Airwaves(ÓThe inside book of Nazi Radio Broadcasting and Propaganda SwingÓ) might describe some of the background of the above story. In chapter 8: ÓThe Battle StationsÓ and Radio ArnhemÓ(The latter also heard by Jan Erik RŠf) it is indicated on p.224 that Óseveral mobile transmitters were establishedÉin co-operation with units of the Wehrmacht propaganda Department(OKW/WPr) and the ÓSS-Standarte Kurt EggersÓ, which had a broadcasting section of its ownÉÓ[14](Horst J.P.Bergmeier and Rainer E.Lotz: HitlerÕs Airwaves, Yale University Press, New Haven, CT/London, UK, ISBN 0-300-06709-7)


Picture: News item from DX-Radio 1944 about Soldatensender Kolibri, Aten and Mittelmeer.




A long-wave station previously used in Rovaniemi, Finland, was established at Hellerud near Tveten gŒrd in the Aker municipality near Oslo towards the end of WW2 and used for Kšnigsbergradio programs. It announced itself as ÓHallo NordenÓ, and broadcast on 297 khz, 1010 metres longwave.


But during these troubled years, the occupants of course could have established the stations and used the frequencies they wanted.


Two stations from the same site might be indicated by the information from the Godlia source of Medium Wave reception in 1942. (However, reception so near the site might have been a harmonic of the original signal, then likely to appear at least on 594 kHz Medium Wave)


If there was another station at Tveita it might have been a ÓSoldatensenderÓ or a station relaying a regular German service from Óthe ReichÓ, such as Deutschlandsender.


The station might have been briefly used as part of the NRK domestic network shortly after the war, but after this Norwegian authorities for over 15 years never managed to come up with any decision for use, and eventually scrapped it.

[7] Actually, the Swedish program of DES,  "Die Deutschen Europasender" (name of the official external services of Reichsrundfunk for Europe) was transmitted via Heilsberg II (the second 100 kW transmitter at this East Prussian site [today's Polish name: Lidzbark Warminski]) at March 15th 1944 on the former frequency of Kattowitz [Polish name: Katowice] 868 kHz and via "WeichselÓ (Warschau-Raszyn, Polish name: Warszawa-

Raszyn) on 224 kHz  with 120 kW. "Weichsel" was destroyed by the Germans on January 16th 1945(RiR 40/October 6th, 1945 had a picture of this site in ruins and intact); Heilsberg II was without modulation on January 25th and destroyed by German forces on January 31st 1945.(Bernd-Andreas Mšller)

[9] Documents re. the Norwegian transmissions from Kšnigsberg were spotted in documents of Reichsministerium fŸr VolksaufklŠrung und Propaganda in the former Zentrales Staatsarchiv der DDR in Potsdam(signature 50.01). Now in Bundesarchiv in Berlin(signature R55).

[10] Bernd-Andreas Mšller comments: ÓThe telescope masts and also the self radiating round steel masts of the mobile transmitters for long waves were temporary antennas only; the usual antenna systems for these frequencies consisted of three T antennas between three masts (named " DreieckflŠchenantenne ").

[11] Kurier 11-12/2001

[12] Bernd-Andreas Mšller also questions some of this information.

[13] The original frequency range of transmitter "L" was 136 to 500 kHz; perhaps it was changed later. (The transmitter "M"(Sender Martha/Soldatensender Monika(Belgium/later ex-USSR) was changed to MW in July 1945 in Germany.)( Bernd-Andreas Mšller)

[14] The "Soldatensender Lappland" and all other German "Soldatensender" were radio stations for the German soldiers; while the battle stations in 1944/45 ("Amhem"; "Krautland calling"; "Radio 45"; "Jerry's Front Radio" etc.) were "Kampfsender"; propaganda stations targetted towards the Allied forces. Both kinds of stations have used mobile transmitters. (Bernd-Andreas Mšller)
