A close friend who just passed away....once told me his Morse reading speed was limited by his typing speed and he was no slouch at that.
He was a US Navy Crypto Intercept specialist and dealt with some very interesting work.
He had friends aboard the USS Pueblo which was attacked and seized by the North Koreans and its crew held captive for a period of time and were handled very roughly by the North Koreans.
Our collective Class test scores improved as we began to master Morse even at a snail like pace.....until one of the Monitors tweaked to the onset of pencil tapping.
