Digital Communications 75 years ago

Here is a nifty slow-motion video showing how DIGITAL communications was received 75 years ago … a truly ingenious mechanical invention and fabrication …  the Model 15 Teletype page printer!

Remember, this device ran 7 times faster than the video shows — it printed a super-speedy 60 words per minute … the video, however, lets you appreciate the clever mechanical movements used to decode the  5 data bits ( ones and zeros, as we say today) into the proper letter to be typed.

Does your CW have rhythm ?

A couple of very old military training films — but the points they make are still just as valid for sending Morse Code today as they were back then …

And here is a more modern one that, to my great surprise, uses a scheme that is almost identical to what I devised back in 1955 when I was trying to learn the Morse Code !!

There are many other schemes and ‘tricks’ to help learn and remember the characters — one of them will click for you.
