Navy Automated Morse Code (CW) Equipment

I know very little about how this worked so far - please send me e-mail with corrections, clarifications, additions, etc.

At shore transmitting stations, Morse code messages could be punched onto paper tape and then sent via a CW or FSK keyer which controlled the transmitters. Normal shore-ship transmission was around 20 wpm, but high speed links between shore stations could run up to 400 wpm.

At the receiving end of a high-speed link, Morse was recorded in ink onto a paper tape - the tape could be read by Radiomen who printed the messages using a typewriter (mill). Code recorders were also used for intercept work.

I have got the pen and capstan motor working, but am missing some piece that guides the paper tape past the pen - please send me e-mail with any info or photos of this unit

AUTOMATIC RTTY-MORSE CONVERSION

In the 1970's there were automatic Baudot-Morse and Morse-Baudot converters >> I need more info on this
