The requirements for both amateur and commercial licenses can
be found in old books. C.1929, from the "Radio Manual" for the
highest class Commercial Extra First was 30 WPM sending and
receiving Continental code five letter code groups and 25 WPM
plain language American Morse. The next was the First Class
requiring sending and receiving of 20 WPM Continental code groups
and 25 WPM plain language.
The ham requirements are probably there too but I think the
highest class ham license was the same as the Commercial First.
American Morse was required because the connections between
land stations was by conventional telegraph circuits which used
American Morse. A commercial op in a land station had to be
proficient in both. In the bio of Ted McElroy is says he had to
learn Continental code when he was hired by RCA because he had
previously worked only on land lines.
The spacing of the signals in the recording, when slowed
down, seem to show the slight irregularities typical of a hand
key. Most of the remarks by the narrator about bugs is nonsense.
Also, comments in books from around 1900 about land telegraph
operation suggest that a good operator could work at 40 WPM or
higher. The speed and accuracy required in large office
operations was pretty great and necessary to earn top dollar.
There were not many regulations regarding distress traffic
before the Titanic went down. Its sinking resulted in a
considerable expansion of regulations, so I don't know if there
was a regulation about the speed of distress traffic but later
practice was to avoid high speed in order to make sure distress
messages were easily received.
I realized after listening that the narrator is not N1EA
