On the occasion of the 75th anniversary of the end of World War II, and thus Denmark's liberation, the call sign OZ75MAY was active in May 2020.

However, Bornholm Island was not liberated until 5 April 1946, so Danish radio amateurs will be active with the two special call signs OZ75BO and OZ75MAY in the period of 1-11 April 2021.

Amateurradiostations active from Bornholm and surrounding islands use the call sign OZ75BO.
Participants in the rest of Denmark use the call sign OZ75MAY.

There may be activity on all the bands, including the WARC bands and SSB, CW and all Digital Modes may be used.

All QSOs will be uploaded to Clublog Log Search, eQSL and Logbook of The World. We will NOT upload to other logbooks. We will try to upload all logs daily, but do not expect the log will be complete before approximately 1 May 2021.

OZ75BO / OZ75MAY operators will try to be QRV via Clublog Live Stream OZ75BO or OZ75MAY. However, there will be some delay, because not all operators will be using live logs. We try to upload full log approximately once per day including upload to eQSL and LoTW.

Please take a look at the activitycalendar for OZ75BO or OZ75MAY to see our planned activity.

We open up for QSL request via Clublog OQRS AFTER the event and when the event log is completed from all operators.

Peace, Freedom and Reconciliation
Party of light to celebrate liberation . . .

Ever since the message of Denmark's liberation came through the radio on the evening of May 4, 1945, light has been associated with the celebration of this event. In many Danish homes, it is still a constant tradition to shine the windows on this evening.
The residents do in Haderslev too, but here the celebration has an extra and much larger element in the form of Haderslev Lysfest. The party of light dates back to 1950. At that time, Colonel Gabel-Jørgensen took the matter into his own, as he learned that there would be no official celebration of May 4. At a few days' notice, he stacked an arrangement on the legs of the Haderslev Barracks, which included hoisting Dannebrog, speeches, and that 400 candles were lit in the barracks windows. To the great surprise of the colonel, over 2000 people showed up to the event, which has since continued.

This year, hundreds of candles will also be lit at the Haderslev Barracks on the evening of May 4, and traditionally, thousands of citizens will gather to listen to the play of the original message of freedom, see the candles lit in the barracks windows, hear the candle party speech and sing along to common songs. In addition, there has also been a special lighting event in recent years.
However, Haderslev Lysfest is more than the beautiful and moving event at the barracks. In 2014, the barracks and Haderslev Municipality initiated a collaboration on a renewal of the candle party, which today includes a number of other events that all touch on the candle party's overall messages - peace, freedom and reconciliation.

The candlestick program includes debate meetings, lectures, exhibitions, music, films and theater. The many events focus not only on historical events, but also on current security policy issues. Haderslev Lysfest has up to 10,000 participants, making it one of the country's biggest celebrations of Denmark's liberation on May 4, 1945.

So all the informations on this page is to inform you about the time when Denmark was freed from the German occupation and the end of the World War II. This happened in most of Denmark on 5 May 1945. The eastern island Bornholm stayed occupied of the Russian until 5 April 1946 and this also was a day of happiness when all of Denmark finally became free again.
In May 2020 Some Danish Radio Amateurs are going together in a Team to celebrate this special day 75 years ago, and you may find informations on this website for your chance to adopt a special Award.
