I have a particular problem with copying random text (code groups or words). When I pause to think I miss several of the following letters. Is there an exercise which will help break the "stop to think" behavior? I know this indicates I don't have a sufficient reflexive recognition of some characters. Has anyone else encountered this and overcome this mental "pause to think" block?
You are on lesson 1 ??
If you are working learning the characters then you might have to think to recognise them, in which case you will be slower with the new characters.
You learn by:- hear morse -> think char -. repeat repeat until it becomes an automatic responce - like most things you do
you need to make sure you are actually decoding, rather than just listening.
Hearing a new char and thinking - "I didn't get that is must be the new char" is not actually decoding . .
( some ) people get 90% on an ( early ) exercise say lesson 3, but when they go to the next lesson ( 4 here ) there are now two chars they don't know
so they hit a bit of a wall . . .
Fatigue will get you occasionally, so you will miss some. Do what nonag says in this case . . . .
You have to choose - stay at your target speed ( raw Koch ) or give youself extra decode time ( Farnsworth ) ( this is when you are learning the chars - not speeding up )
The only advise we can give ( because we don't know what you are like except what you tell us ) is that you need to make real progress - else you will get bored and join the 90% or so who give up after a bit. ( some come back years later - often with more realistic expectations )
if you NEED to, then use longer space between chars.
TonyD has some concerns about the amount of extra space . . . https://lcwo.net/forum/2123/Started-today
There are NO tricks to get your brain to do things, especially at lesson 1
