Not exactly DX from my location, but I am also a QSL collector and the Dutch Coastguard issues this nice QSL email. So here it is. I received my QSL Dutch Coastguard Den Helder 518 kHz for one of their NAVTEX transmissions.
The Dutch Coastguard has a nice website in English, but their history is best told on the site in Dutch (use Google to translate). Coastguard activities in the Netherlands started following a tragic incident with a Navy ship “Zr.Ms.Adder” in 1882. The ship sank near Scheveningen, but nobody noticed the ship was missing. Only when the first bodies washed ashore alarm bells went off. From 1882 onwards the crews on the lighthouses – which were already there as navigation aids – had to monitor traffic actively and had to report incidents.
Over the years 6 different departments in The Netherlands developed activities on the North Sea. Fishery, Traffic, Justice, Defense, Finance and Internal Affairs. In 1987 it was decided these departments had to work together from a central location in IJmuiden. I have a PPC QSL from 1993 indicating that in those days radio traffic was limited to emergency frequencies (2182 kHz and VHF) only. Telephony/telegraphy including weather and navigational warnings were broadcast via PCH Scheveningen Radio.
In 1994 it was concluded that the cooperation between the 6 departments needed improvement. The Coastguard was established as an independent entity, with its operations coordinated under responsibility of the Royal Dutch Navy. As a consequence the Coastguard centre moved to Den Helder which is the main port of the Navy.
With more an more communication going via satellite Scheveningen Radio closed in 1998. My guess is that since then navigational warnings via NAVTEX were transferred to the Coastguard.
