On March 2, 2022, Michael Kuhne, DB6NT, and his son Matthias, DK5NJ, established a new world distance record at 134 GHz by making contact using CW over 157 kilometers (98 miles) between the summits of two mountains in Germany. The portable microwave stations were located on Schneekopf mountain in the Thuringian Forest and atop Fichtelberg mountain near Oberwiesenthal.
Check out the video of the record-breaking contact.
