Shortwave Radio from Winsen is an easy catch here. For a little compensation they will confirm your report with a traditional QSL card. You can read the details on their website.
The station is located in Winsen “on the river Aller”. So that is the Winsen located 20 km north of Hannover, Germany (there is another Winsen south of Hamburg). They broadcast on 6160 and 3975 kHz. Next to their own program Shortwave Gold there are various other program producers that use the Shortwave Radio facilities.
The signal from Winsen is probably the safest shortwave catch in my place, by groundwave on either frequency. Some 40 km southeast from here, beeline. And there’s a lot that is fun to listen to.
