 In the early days of wireless and even wired communication, messages were sent in the form of Morse code. Of course, the signalmen operating the earliest wireless sets, the soldiers of the "Spark Companies", had to be trained in using the manual morse key to transmit and to record Morse code transmissions by ear. In the early days of wireless and even wired communication, messages were sent in the form of Morse code.

 This was not a problem, as long as only professional radio operators and radio amateurs were trained as signalmen; they mastered the Morse code in sleep, almost as well as foreign language skills. This was not a problem, as long as only professional radio operators and radio amateurs were trained as signalmen; they mastered the Morse code in sleep, almost as well as foreign language skills.

 It turned out, that **High speed telegraphy** would not meet the requirements. With high speed telegraphy systems, messages could be transmitted in high speed morse code easily. But these had to be printed to paper, and then decoded in a tedious way from the Morse code to letters. If the operator's Morse code knowledge was poor, this step of reading and decoding the Morso code paper tape stripes needed as much time, as direct Morse code reading from the headphones. So this procedure was abandoned after a few years, and more effort was placed on the Morse training, after it turned out, that highly trained telegraphists could read by ear nearly as fast as high-speed Morse code transmission. It turned out, that **High speed telegraphy** would not meet the requirements.

 The use of wireless transmission became much easier, when radio telephony was available. In the case of AM or even single-sideband transmissions, propagation disturbances affect communication quality much more than the use of frequency-modulated sets, which became standard after the shift of military radio communication into the VHF band after World War II. The use of wireless transmission became much easier, when radio telephony was available.

 Without a hard-to-crack voice scrambling or speech encryption, the drawback of telephony was, that transmission could easily be intercepted - stickers "Watch out, enemy is listening!" pointed this fact out to the military users. Without a hard-to-crack voice scrambling or speech encryption, the drawback of telephony was, that transmission could easily be intercepted - stickers "Watch out, enemy is listening!" pointed this fact out to the military users.

-Since the requirements for the signal coming from the receiver to drive the Hell printer and for the signalmen operating the receivers were even higher than for the CW reception, the receivers initially used ([[E-622| Lorenz EO 509/1]] in the [[SE-302|G1,5K Station]]) turned out to be unsufficient because of inadequate sensitive, first the receivers hat to be exchanged for a superhet model ([[Zellweger]] [[E41]]) and shortly after, the Hellschreiber equipment was completely removed from the stations and replaced by the [[Automatic high speed telegraphy system MFA]]|High Speed Telegraphy System Moser-Baer]].+Since the requirements for the signal coming from the receiver to drive the Hell printer and for the signalmen operating the receivers were even higher than for the CW reception, the receivers initially used ([[E-622| Lorenz EO 509/1]] in the [[SE-302|G1,5K Station]]) turned out to be unsufficient because of inadequate sensitive, first the receivers hat to be exchanged for a superhet model ([[Zellweger]] [[E41]]) and shortly after, the Hellschreiber equipment was completely removed from the stations and replaced by the [[Automat.

 For use on long-wave connections and wired communication, the method "Hell" proved enough reliable and remained in use until around 1950, when the [[ETK]] could be procured. For use on long-wave connections and wired communication, the method "Hell" proved enough reliable and remained in use until around 1950, when the [[ETK]] could be procured.

 +A simpler way of making a voice transmission unrecognisable is **voice scrambling** with chopping fragments of a voice transmission in rearranging them in a different order, when reassembled in the correct order after transmission, the voice information can be made audible again. The cryptological security is lower than with character encryption, but it is sufficient to make message content unrecognisable in a tactical context.

 +Work began in Switzerland with the "Chiffrator" MV22 voice scrambling device, [[BBC]] worked on this set after 1956. It never reached field use maturity, but the technology developed was later used in the Vericrypt 1100, [[SVZ-226]] and [[SVZ-430]] voice scramblers.
