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.


How this beast works is a thing of beauty. I wrote an article about it in my weekly “Foundations of Amateur Radio” podcast.
