1944 US Navy Training Film - Radio Operator Training - Technique Of Hand Sending CW with a straight key

This is an excellent US Navy training film explaining the correct technique of hand sending morse code with a straight key.  It is from 1944 and it is spot on.  Well worth a view regardless if you new to CW or an expert (about 9 minutes long).

Be sure to check out my other related post, Army Morse Code Training Film 1966.
