Most people have had the experience of “SELF COMPLETING” word processing. You type in several letters and up pops several choices. I will assume that you have had that experience. At some point in time I started to copy ENTIRE WORDS. They were not what many would expect. They were not 4 or 5 letter words. Some could be 10 or 12 characters in length. A word that long wound just appear in my consciousness. I would recognize the word PRIOR to the completion by the other operator. A couple of things may cause that. ANTICIPATION and also CONTEXT. probably both cause that At slow speeds words take too long to get into the anticipation mode. At 45 and above the self completion is very apparent. It can cause problems as well. You get a word that is not correct. That throws off concentration. You then get out of the rhythm. For me the context is correct probably 75% of the time. I live in Cincinnati. When somebody asks me about CINCINNATI at 45 wpm the first 4 or 5 characters are all I need before self completion of Cincinnati. That is any easy one and rarely is there a close alternative that would come into play. It does take concentration and FOCUS at least for me. There must be a TIPPING POINT (psychologist term) where the probability and consensus context improves your skill. It took me a long time to build speed. About 35 years ago 40 meters had plenty of QSOS at QRQ speeds. That no longer has the numbers that were in existence. Those ops have become SK. Sad to say. Another excellent way to increase your speed is to engage in conversations with your sending being done with a keyboard. About 40 years ago I experimented with a keyboard. Knowing in ADVANCE what the word I was going to send allowed my copying speed to get a very noticeable boost. That occurred within 30 days of steady keyboard use. Going from 35 to 40 + was what I experienced. it works I am not a psychologist or physician. So I only have EXPERIENCED rather than an analytical basis to rely upon. I get into to trouble explaining why. But I can say that the use of a keyboard for sending increases your receiving speed. That worked for me. The sound of what you copy changes slightly at higher speeds. I keep telling myself that I am building a VOCABULARY (sounds). I think that is what infants do. We are all different. But it gets easier with the VOCABULARY building and anticipation which I can only say occurs but I have no idea why. The learning curve is not LINEAR. You get bumps up. Knowing that should encourage people to be persistent. It is not always a grind. Familiarity with the CHANGE in sound, anticipation etc. have been noticed by me in my effort to copy faster. I think people become intimidated. They stop trying to soon. That has been my experience. I kept at it. Nothing is more satisfying than a QSO with a friend at high speed. These are becoming rare. That is why I take the time to share my experiences Good luck 73 Jim W9VNE / VA3VNE Sent from my iPhone > On Dec 29, 2019, at 5:21 PM, [hidden email] wrote: > > Send Elecraft mailing list submissions to > [hidden email] > > To subscribe or unsubscribe via the World Wide Web, visit > http://mailman.qth.net/mailman/listinfo/elecraft > or, via email, send a message with subject or body 'help' to > [hidden email] > > You can reach the person managing the list at > [hidden email] > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Elecraft digest..." > > > Today's Topics: > > 1.

Re copying CW at high speeds:
While learning CW in the military you were also learning to type. Chattanooga Shoe Shine Boy and similar tunes were played while you typed to the beat. CW graduating speed was 25 wpm in 5 letter coded groups. Sometimes numbers were mixed in. And you had to keep up with the mill. (Typewriter with all upper case letters ) In the field I don’t remember speeds much past 20 wpm. Owing to this background I find it difficult to copy in my head. Not that I can’t but I find myself needing to write it down. My advice to new comers. Learn to copy in your head just write down call signs, locations and signal strength. Forget the five character groups. Oh, and do not send faster than you can receive. > Send Elecraft mailing list submissions to > [hidden email] > > To subscribe or unsubscribe via the World Wide Web, visit > http://mailman.qth.net/mailman/listinfo/elecraft > or, via email, send a message with subject or body 'help' to > [hidden email] > > You can reach the person managing the list at > [hidden email] > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Elecraft digest..." > > > Today's Topics:And writing down is not going to fly at higher speeds. > > 1.

(It took me three 200-mile trips to the Kansas City FCC office to finally pass.) All those mental skills that allow an operator to decipher entire words in plain language are of no help with code groups...there's no process of "hearing code groups".?

Before that, the marine Morse bands (especially 400 to 520 kHz) provided far more interesting copy for development of Morse reception skill.? (I usually kept a receiver on 500 kHz/600 meters at night.)?
