[Milsurplus] WWII, Germany and Their 170 KC C.D. Net

[David Stinson]

I found this in the Nov-Dec 1954 issue of "G-E Ham News:"

"During the last war the enemy had a CD communication 
system..... the number of stations on this net was amazing.
The area covered was massive- from the Channel to the 
Baltic in the north, along the Russian Front, south to 
Italy, along the Mediterranean and all the land in between.
... operation took place on Long Wave, down around 
170 KCs.  The operators were good, the discipline rigid
and unauthorized transmissions were nil.  All transmissions 
were coded... not for security, but for speed....."

This network was very active with Civil Defense-type 
traffic- requests for fire fighting, medical aid etc.
Mode was CW.  The piece makes it sound far more
effective and active than our CD nets at that time.

Those of you with contacts in Germany-
Does any technical data about this net still exist?
Is anyone still alive who knew of it?
My major interest is in the antennas used to make this
Long wave network so successful.
