The transmitter in Grimeton -over a 100 years old now- transmitted today. They start it up many times a year, but it only transmits like twice a year and then only for a few minutes.
I’ve been there a number of times when they started it up, even once participated, but now I’ve finally tested the receiver-kit i assembled.
No and Yes.
It’s the only one remaining of the 20 that where build, and it’s also fully functioning. They start it up multiple times a year (30 or so) just to keep it in a working condition. It runs usually like half an hour to avoid excessive wear. The actual transmissions (they transmit for 5 min.) happens only twice a year. The next transmission is most likely on Christmas, they stream the whole event -with explanations- live on YouTube too.
