Malabar, Indonesia

It was formerly well known as a hill station near to the town of Pangalengan for recreation during the Dutch period in Indonesia.

In the era just before the beginning of World War I, two spark wireless stations were established in the Dutch East Indies for naval communications.

Immediately after the end of the war, there were four such stations in the Dutch East Indies, and these were all designated with callsigns in the new PK series: PKA Sabang, PKB Weltevreden, PKC Sitoebondo, and PKD Koepang'.

This massive 3.5 megawatt station was established for communication with the home office in the Netherlands.

However, a tropical lightning strike destroyed some of the equipment and the opening was postponed until repairs were completed.
