A visit to a world heritage - Grimeton radio station

The Grimeton long wave transmitter was built in the 1920's to establish a radio link with New York. It's still working and they are sending 3 times a year on special occassions. It's the only one station of this kind still existing and therefor classified as a world heritage by UNESCO.

The five T-shaped towers form the antenna. It sends with a wave length of 18km, the total antenna length is 4.5km

High frequency generator





The cooling pumps. The fontain in front of the house was used to cool the water.

Very interesting indeed.  I gather that the signal is generated by the alternator. A lot more imposing than a cell phone.
