[CW] Really Fast Hand Sending

Sat Feb 9 19:27:38 EST 2019

CODEX or CODEZ is the measuring group for alphabet cipher groups - GPM
- Groups Per Minute.

As you know, the 2nd class radiotelegraph license (now the T or
Telegraph license) had a code test of 20 WPM plain English and 16 GPM
of code groups.  The 1st class radiotelegraph license had a code test
of 25 WPM and 20 GPM of code groups.  The code generating machine was
set up identically, The FCC used a machine with paper tape and they
ran a calibration run before administering the test.  For Amateur
tests, they played PARIS for 13 times in 60 seconds, for 13 WPM
General examination, and PARIS for 20 WPM for Amateur Extra class
telegraphy tests.

With the machine set up for 20 WPM, the examiner could then put a code
group prepared examination tape on the machine and it would be a
perfect 16 GPM speed.

That is because Morse code was purposefully designed for English
language, E and T being the most common letters are the shortest
letters.  Q, J, Y, Z and X aren't used that often and they're made of
longer sequences  of dots and dashes.

So at a certain dot speed (dashes are three times as long) English
language comes out faster than random code groups.

16 character per minute speed when sending code groups becomes 20
words per minute counting five letters per group and five letters per
word.

I agree 50 wpm typing on a MILL error free is tough to copy because at
least with me, I jam the keys trying to type so fast.

People say your code copying speed on a MILL (typewriter) is one half
of your typing speed.  That is if you type 60 wpm, you would be able
to copy 30 wpm Morse.

So that means that McElroy who copied 77 wpm must have had a typing
speed of 154 wpm - which is darned fast.  He was known as a very fast
typist, thus his Morse reception speed was fast.  He could probably
copy faster, but he could only type so fast even when he could type
over 150 wpm.

Its been almost 50 years. We were using a tty baudot tape through it, to measure both our transmit speeds, and operators ability to copy set speeds that they had to copy for specific rank measurements.   I had learned high speed, using military magnetic tapes, up to 25 wpm, but each tape could be sent twice as fast, so we could actually test up to 50 wpm. It wasnt until I got on a high speed circuit for several weeks, that I could maintain that rate for a few minutes at a time. Of course,we were typing on a MILL It ruined me for trying to copy in my head.

Sitting an automatic keyer so that it cranks out PARIS 25 times, gives you 25wpm, etc.  Counting WPM, as most know, can beany sort of word from one letter, to a dozen or more in a sentence, as long as the keyer is set for PARIS.  I had never heard that, until I had to come up with a test speed to set up a keyer, and after a couple of days playing around, measuring each letter, found the PARIS name fit.  Later I saw I had rediscovered gravity.
