Many thanks to SWLing Post contributor, Gérard Koopal, who writes:
This might be interesting for your followers in Europe and especially for those living in or nearby Germany.
On the 9th and 10th of November, the Eifeler Radiotage are to start transmitting in German from a Cold War bunker in Germany. There is also a possibility to visit the location (Kall Krekel). Below is a link to their homepage where you can also find a few videos from the Cold War radio room which is still functional and in use.
Thanks for the tip, Gérard!
