Vintage 1944 Radio Operator Training: How to Send Morse Code (CW) by Hand

In this vintage United States Navy Department of Defense (DOD) film from 1944, the technique of using a straight, mechanical hand key to "send" "International Morse code" (as different from "American Morse code", used by railroad landline communications) by radio to ships, and other receiving stations is explained.
The hand sending key is detailed. Then how to use the key to tap out Morse code, which keys a radio transmitter.
The film specifically trains the viewer on the important parts of the transmitter, tension spring, adjusting the hand key contacts, and adjusting the tension spring of the straight key. Then, the elements of Morse code, the timing, and the parts of the Morse code communications operator's body that function when transmitting the CW code are explored. The film focuses on the importance of correct body position and hand key operation. A lot of these details are still important for the modern amateur radio operator interested in using Morse code on today's world-wide radio technology that still uses shortwave radio spectrum to send and receive these CW signals.

I remember my first job as radio operator in a foreign cargo vessel I felt nervous because that was my first time to operate such big radio console and send message on a radiotelegrapy mode. I felt relieved after sending my first message thru Nagasaki radio.

CW is relaxing when you get into the frame of mind, like meditation, they they should teach morse code to people that can't relax ;)

I wish that was true for me. ☹️ I always got too uptight receiving. I would actually start sweating. I finally realized that I was not enjoying it at all so I sold all of my equipment. I wish I could have become proficient but it never happened...

Thanks OM for the view. I learned much here, and will practice straight key. Love using electronic keyer, but old ways are good to maintain and pass on.

Great tips about CW operation (from PY2FZU)!!!

So, you survived. How was the swim?

Hmm and now we just text people

Why didn't they just use email? What a joke

Yer so funny.

us Propaganda

[@sluggger]

What part of this is propaganda? It's purely a training film on how to use a straight key for sending morse. There's no agenda. There's no subtext.

[@bibsythecottonelf7147]

S_G__GDX_X bear with me... maybe he’s typing in Morse code, and he’s Russian, and like 72, so by the time they stopped teaching morse code all he’d ever learned was “us propaganda”
