Hitlerjugend: An In-Depth History: HJ-Nachrichten
by Arvo L. Vercamer

This specialized group focused its efforts on training its members to serve the needs of the German military's communications and signaling services. The boys learned to operate Morse code equipment, wireless transmitters, laying cables, erecting lighting and speaker systems for NSDAP and other official functions, etc. The primary sponsor of the HJ-Nachrichten youths was the German Reichspost, although the German Army also participated strongly in the training efforts (the German Army also provided many of the state of the art communications technologies, which the HJ-Nachrichten members used to learn and train with).

The HJ-Nachrichten training regimen was divided into three separate phases:
Phase I - this training period lasted six months and was generally seen as a basic introductory course into communications and signalling intricacies. Upon graduation of this phase, the HJ-Nachrichten candidate was awarded a Nachrichtenschein-A (signals certificate class A). A special "A" badge was also awarded.
Phase II - this training phase lasted approximately two and a half years. Additional skills were taught bejond those taught in phase I. Upon graduation of this phase, the HJ-Nachrichten candidate was awarded a Nachrichtenschein-B (signals certificate class A). A special "B" badge was also awarded.
Phase III - this training phase was essentially a final special course, which did not last too long. Specialized communications and signallinkn skills were taught bejond those taught in Phases I and II. Upon graduation of this last phase, the HJ-Nachrichten candidate was awarded a Nachrichtenschein-C (signals certificate class A). A special "C" badge was also awarded.
