Skagen Radio (OXP) :

 

here is a clip from 2182 kHz - Holyhead CG (G) working with Malin Head (IRL), additionally you can hear Blavand Radio (DNK) at 0'41, Skagen Radio (DNK) at 1'00, and Helsinki Radio (FIN) at 1'10 (Rudy van Dalen, 1992)
in 2021, Skagen Radio was one of the few remaining stations in the north sea (rb)

 

short, friendly, correct: a QSL-letter from the collection of Dieter Pohlmann (1976)
from 1981, see this PPC from the Skagerrak, northern tip of Demnark (rb)
signed on the very same date as the PPC above, this letter tells Rudy van Dalen, that generally no QSLs will be given... :-(
in 1985, Frank Schüttig received this PPC
here a QSL for a DSC (= digital selectice call) transmission of Lyngby Radio OXZ carried out from Skagen transmitter (Michael Oexner, 2010)
