Visited Grimeton radio station with an English guided tour in August 2018 (I booked in advance through the official website for 120 SEK). It is rather small, but contains all the original equipment (produced by General Electric in the USA) in excellent condition plus some other related exhibits. Today radio station is occasionally used by amateur radio enthusiasts. The station is striking example of the pace of technology development. The wall mural shows 9 radio stations from Hawaii, USA (central radio was on Long Island), Poland, Wales and Sweden but only Grimeton station survived in its entirety. (Another murals probably with some irony compares the site with Giza pyramids, Great Wall and other big elephant site!). Totally agree with previous reviews that the site is unique, pleasant and interesting.
