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.
Nice rig!
I live near WPR in Wisconsin. The equipment and changed and moved around, but it began broadcasting in 1922 and is still a major station.
