 in the 
internet I have read that DK8KW, Holger Kinzel at Peine, also has a DEBEG 7121 
transmitter, including its full documentation. He had also used it for the the 
beacon he had operated around 500 kHz.
 
 Perhaps You can get 
the information from him.
 
 OK?

 Hello 
  all,
 some month ago I got two PA modules for 500kHz. Unfortunately I 
  got only a few pages and a schematic about the modules but not about the 
  complete transmitter. The modules were introduced to me as parts of a former 
  Non Directional Beacon made by Siemens.
 
 Now I compared the inside view 
  of the complete transmitter in the rudimental manual with an inside view of 
  the famous DEBEG 7121. It's quite the same.
 
 That's my chance to find 
  out the information I need about the units. At the moment the PAs make about 
  30 db less than at the input. To find out, what might be the problem I need to 
  know what impedances in and out, what power in?
 
 I am looking for
 - 
  user manual
 - service manual.
 
 But any answer to my question (in/put 
  / power/impedance) would be useful.
 
 Of course I'd like to own a 
  complete 7121 transmitter - but I think there are some more here who would 
  like, too.
 
 tnx es vy73 Horst DO1KHS/DI2AN
