Over at the RadioTelegraphy Forum Adam, N0SSS, posted this thread , it’s a lovely treatise on the musical relationships in Morse code. In his work he coins the term “Vail Effect” the aural illusion of the code slowing down. This is fascinating stuff, yet the CW community seems to have missed it. I hope it gets linked around.
I’ve been lucky enough to catch Adam at the key a couple of times. He runs an Argonaut into a big loop and he’s got a great fist.
