High speed morse keyer - this page is a stub

MGS-165 is an electronic morse keyer, also known as a high-speed burst encoder, de­ve­lo­ped around 1972 by RFT in Chemnitz in the former DDR (East-Germany) for use by the NVA – the army of the DDR. The device is suitable for the transmission of morse code, and consists of a modified typewriter and the actual keyer. It was succeeded in 1982 by the more versatile MGS-80, which was also capable of sending signals in the ITA2 telegraphy alphabet (telex).
