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.


You sure that qualifies as “dull”? Does that mean they actually fired up and operated this gigantic thing? https://en.wikipedia.org/wiki/Grimeton_Radio_Station
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.
Wow that’s neat!
That’s quite an understatement. The things Alexander came up with to make it work at the time are truly amazing (still are today)
It’s really neat!
It’s honestly incredible stuff. I’d love to make myself one of those receivers & enjoy the yearly test.
I paid sek 565:- (roughly Eur 51 / $59) for the kit on the photo (excl batt.) but shipment might cost you more, but you can ask them ;)
A lot of the stuff posted here is too interesting, IMO.
I think it’s more about the things other people would find dull. That we find those kinds of things interesting is why we are here to begin with.
Agreed! But I think that’s on us then. Apparently dullness is a very enjoyable lifestyle.
I would not wanna trade with those who thought “So? You heard a few crackling beeps from a 100+ year old machine, did you not get the message? We have whatsapp and spotify now”
