  Prior to the outbreak of WW II a signals intelligence collection had been established in Germany.  Each Lft. had thus a subordinate organization, which for reasons of deception and concealment had units with names related to weather service.  In each Lft. area there was a Wetterfunkempfangs-Leitstelle (W-Leit) with a number of subordinate operations-centers called Wetterfunkempfangs Stellen (W-Stellen).  The actual collection was done by Wetterforschungs Stellen (Wo-Stellen).
The manning in the Lft. area was provided by the III Battalion of a Ln.-Rgt, the W- and Wo-Stellen were manned by 9 and 10. Kp of that Battalion.
 
     
  Right after the occupation of France the Reichpost-Zentralamtes (RPZ) established a number of FuMB sites on The Channel Coast. The sites were equipped with receivers, which covered the frequencies from 75 - 300 Mhz.  The task of this organization was to follow the development of radar in the UK, so it was more strategic and operational rather than tactical in nature.  In the year up to 1942 the number of sites expanded, and the initial makeshift organization subordi-nated to Lft.2. was absorbed in Ln-Rgt.3 ("CONDOR").   
  Subordinate to Lft.3. the following units have been identified:
W-Leit Stelle 3 manned by Stab III/Ln.Funkhorch-Regiment West located in Noisy by Beaumont with accommodation in a castle in Chambley.
W-3 in La Celle-St. Cloud and W-25 in the Brest area.
 
  Central direction was conducted the by the Funkleitstand des ObdL organized in 7/Ln-Rgt. ObdL.  Over time the function of the organization became of a more operational nature, tasked with collection against the allied air forces in order to establish AOBs and operating patterns.  This organization was thus able to detect and follow the Bomber Stream based on it's emissions, but this information was not passed on in near real time to the JDs, much to the dismay of the commanders.  Some of the first equipment employed was given the covername Windmess Stelle (WIM) and the designation FuMB a - h.  It is interesting that some of this equipment was operational in Norway in 1945.

      As part of an all encompassing re-organization of the Flugmeldedienst, Ln-Rgt. Reich was established in OCT 1944 as depicted.  This organization was responsible for intercept of electronic emissions in all frequency bands, with all modulations and signal formats, exploitation and jamming.

  When manning a Stelle these units were employed in the smallest organizational entity : a Trup.  Elements - maybe the entire Kp. - from the following units have been identified in Denmark.  This list is definitely not all exhaustive.  In the source I'm working from, only the name of the Stelle is mentioned in most cases:
