The Southern Jutland Radio Museum has been visited on various occasions by journalist Niels-Henrik Jensen, who, in addition to his journalistic background, is also trained as a radio mechanic.

Niels-Henrik, who is interested in the story of Kaj Munk, comes to the Rectory in Vedersø, and during these visits, as a radio mechanic, has become annoyed by the poor condition of Kaj Munk's old B&O Master 40 S, which was launched in the autumn of 1939/spring of 1940.

The radio had a broken dial glass, a missing button and a missing back cover. Furthermore, the radio was in no way functional.

From his visits to the Southern Jutland Radio Museum, Niels-Henrik knew that the Radio Museum has the expertise and the necessary components to restore an old tube receiver.

Niels–Henrik therefore suggests to the Vedersø Rectory Museum's general manager Lisbeth Lunde Lauridsen that an inquiry be made to the Southern Jutland Radio Museum with a view to restoring the old radio.

The Southern Jutland Radio Museum naturally agrees to such a task, and after the radio is brought to the Radio Museum's premises in Sønderborg, a small team of skilled technicians gets started on the task.

The radio becomes functional relatively quickly, the scale is glued – no substitute is used, as it must be the scale Kaj Munk was looking at – the missing button is found, and a new back cover is made.

In collaboration with Lisbeth Lunde Lauridsen, it was decided that a small CD player would be discreetly mounted under the radio, which, via its own amplifier and a newly built-in speaker, could play a number of sequences typical of World War II and Denmark.

The sequences are, for example: Poul Henningsen, who talks about his special patriotic songs, BBC broadcasts with the well-known code names for the freedom fighters, a live recording by DR of an act of sabotage in Copenhagen, originating from a wire recording from the turn of the year 1949/50, and of course the message of freedom from May 4, 1945.

These sequences are "burned" onto a CD, which during playback is accompanied by scale lights (originating from an LED light strip built into the radio), giving the experience of a "living" radio.

Kaj Munk's radio is now fully restored and, after a final polishing of the cabinet, is ready to return to the museum at Vedersø Rectory.

A little of the restoration can be seen in the series of images below.
