Grimeton Radio

Why an essay about a radio station in Sweden?

Grimeton is an early longwave radio station built in the early 1920’s, that has been preserved as a historical site. It’s the only remaining example of an early electro-mechanical VLF-Transmitter. It is still in operational condition, and usually sends out messages twice a year: On Alexander Sunday (Sunday at the turn of the month June / July), and on Christmas Eve morning.
The messages are transmitted under the call sign SAQ in Morse code and can be received all over Europe.
More information is available on Wikipedia and on the SAQ-Homepage.
