Alphabet table
editThe alphabet table can be mostly verified from http://www.navy-radio.com/morse/message-wheatstone-japan.jpg by Col Reeder G Nichols 15 August 1945. But it can easily be verified from the Morse code and the • and — mapping. So @John Maynard Friedman: there is no need to mark this dubious. We might need verification for the non-standard " \ ⠇⠳⠇⠇⠳⠂" though. Graeme Bartlett (talk) 23:35, 15 March 2021 (UTC)
- @Graeme Bartlett: at least that is somewhat closer to a usable citation. The current simple http://www.navy-radio.com/morse/ is just not good enough because it is not amenable to verification: that is what makes it dubious. I have left a message to the editor who contributed it, to ask for where they found it.
- You may have noticed that I have been trying to trace the provenance of the backslash symbol, which is certainly present as a key on Kleinschmidt's and Wheatstone's perforators but can find nothing on its purpose. It wasn't transposed into Morse so I can only guess it was an untransmitted control function. --John Maynard Friedman (talk) 09:01, 16 March 2021 (UTC)
- Yes, it was message-wheatstone-japan.jpg, which unfortunately is insufficient but better than nothing. So I have updated the citation and tagged it as 'better citation needed' giving as reason that it is not the full alphabet, not the full number range and none of the punctuation or control elements. But it is better than nothing and hopefully someone will turn up an 'all keys test pattern' to replace it (but it is well worth keeping anyway, perhaps as an illustration). --John Maynard Friedman (talk) 17:07, 16 March 2021 (UTC)
MacArthur message to Japanese Emperor & Co.
editIn case we find a need for it, I'm just parking here a book reference that also has an image of Gen. MacArthur's message:

The image of the message could be uploaded to Commons if anyone feels it worth the effort. --John Maynard Friedman (talk) 17:01, 16 March 2021 (UTC)
