As a teenager (1950's) I used an original Instructograph to learn Morse Code for my ham licenses, and had obtained a speed of up to about 30 wpm.

Now 70 years later, I have obtained both 3-post and 4-post Instructographs to be connected up to recoup my code and reapply for a new Extra ham license. I would be very grateful if someone could please detail for me how to connect the batteries, headset and oscillator to both of these types (3-post and 4-post) Instructographs. The machines are the post-crank type with electric motors.

    $\begingroup$ FYI, in the USA, Morse code is no longer required for any license class, not even Amateur Extra. $\endgroup$

  • $\begingroup$ Looks like an interesting project. Wouldn't be easier to use one of the many internet apps for learning morse code? Take care. $\endgroup$
