The story behind OZ100DVI

Throughout 2017, we will commemoratethe 100th Anniversary of the Treaty of the Danish West Indies. InDanish they are called "Dansk Vestindien" or "De vestindiske er".

After the Islands came under the USA, they were renamed U.S.Virgin Islands. They are composed of the main islands SaintCroix, Saint John, and Saint Thomas, and many other neighbouring minor islands.

The team behind OZ100DVI

We are a HAM radio club with the call sign OZ7SKB, located in the city of Skanderborg on the East coast of Jutland in centralDenmark. Believe it or not, in Skanderborg Lake there is an island called Saint Thomas. This was reason why we gotinterested in our local history, but also in world history and the Treaty of the Danish West Indies.

Saint Thomas got its name from a flamboyant local baker, Thomas Brdstrup (1793-1877). In summer he enjoyed sailinghisboatarmed with three small naval canons on each side. While cruising on the lake he would salute the locals on the lakebank. In winter he would take dug up earth from his property and dump it on the iced over lake. When spring came, the earth would drop to the bottom and eventually create the island of Saint Thomas.

Our goal is to promote our wonderful radio hobby in the public and at the same time commemorate the Treaty of the DanishWest Indies on the air. We will be present at various local city events and aim to interact among others with the local sailingclub and scout groups. On our to do list, there are activities such as working portable from our local Saint Thomas Island,hiking trips/working SOTA from the nearby Danish Lake Lands, and being on air from Flora Fauna area.
