In the fourties, an automatic high speed telegraphy transmitter, which was used by the Swiss Army for morse code training purposes, has been produced by Moser Baer, Sumiswald. The precision mechanics company Moser Baer does still exist nowadays, today the precision mechanics and eletronics company Mobatec and Mobatec, who do produce the famous Swiss railways clocks are the successors of the original company.
The high speed telegraphy transmitting system "Sendegarnitur SU-ZG-SL 200a", the crates are marked "AMS",
has been developed by the clock maker Moser-Baer, Sumiswald. All units have designations with a small letter "a" at the end. The keyboard perforator SL 200a, which comes in a separate crate (48,5 kg with accessories) and is powered from the power supply with
110 Volts AC, a punched paper tape with the text message is generated. The punched paper tape is inserted in the transmitting head of the transmitting unit, so that the first hole of a line is on top and the second hole is below the transport holes; the operating instructions recommend to mark the beginning of the paper tape with an arrow. The transmitter Unit and the power supply unit SU 200a, in which the necessary voltage of 110 Volts is generated, are both installed in a bukky and heavy (43,5 kg) wooden crate. I would be interested very much in additional information about where and how this
equipment has been used. As far as I know, it was in use only for instruction and
morse code lessons and not for "real" high speed telegraphy communications. weitere Lektüre: © Martin Bösch 14.2.2013
