  Jamming of GEE.  
     
      Based on recently received information I revisited all my sources on this subject.  One of them should have rung a bell 6 month ago.  It's a technical report complied in connection with exercise POST MORTEM.  It lists the stations in Denmark (see below map) and states (in extract abbreviated by author):  
      "The purpose of the jamming was to up-set Allied navigational transmissions. Each Heinrich I could transmit on 20.8 - 79.9 Mhz".  [This was the frequency used by GEE [10.0] Radio Navigation Systems In "Funkstör" by Fritz Trenkle "Heinrich" is explicitly mentioned as a GEE-jammer].  The report continues: "The antennae (sic) are of the wire basket cylinder broad-band type suspended vertically on poles 15 to 20 m. high". This correlates with the below pictures from Odense and Vittrup.
