With centralization and the introduction of remote operation it is not always easy or even possible to identify what you actually heard. Sending DSC messages with MMSI 002301000 this station is referred to as Mariehamn Radio in the DSC community. The ITU list gives MRCC Turku as the station however, and Turku is definitely the control centre for operations in the western part of Finland. Helsinki seems to be the other main control centre.

Anyway, as QSL Mariehamn / Turku Radio for a reception of their DSC test message on 2187.5 kHz I got a short email from mrcc@raja.fi, which is the email address for the headoffice in Turku.

In the old days things were easier: I added the QSL I received in 1989 for my reception of Mariehamn Radio on 1852 kHz which definitely originated from the Aland Islands.

UPDATE:
A friendly Turku operator explained it all to me. Big thank you to this anonymous contributor to my blog:
