European stations in 1926/27

The scans below are from the book "Het Radioboek voor den Handel, Amateur en Luisteraar" (the radio book for the shops, amateur and listener).
It is written by  J. Schiere and published by Karel C Schoemeijer in Bussum, the Netherlands.
The book mainly describes the technical part of broadcasting, but also tackles broadcasting development and radio shops in the Netherlands.
Being second print, the numbers below must be valid for end 1927, early 1927. They show the main broadcasting stations of that time.
