[CW] McElroy Chart of Codes and Signals.

[Bruce Prior]

Using dots and dashes is a poor way of learning Morse Code. Singing dits and dahs is much better. See the attached file.

I have on my Internet Archive files a McElroy Chart of Codes and Signals.

Highlight of the American Morse section:

You will notice $ is SX sent as two letters in American Morse, it sounds like "SL" in International Morse.

So the sound of the dollar sign was never SX, but SX was what was sent in American Morse.  That being said, I received a telegram from Netherlands coast station ScheveningenRadio / PCH and RCA San Francisco with the operator sending very slowly "SX" for dollar sign - which isn't even admitted in telegrams in International service.

International Punctuation from the same chart - the only thing that has changed Post WWII is that left parenthesis became KN and right (ending) stayed the same as KK.
