I tried first to set the lowest speed that the settings allow.
Something like 10/3 and five seconds between words and two characters in a group.
It turned out to just learn the letters themselves.
But any minimal change in speed leads to a strong pullback in recognition skills.
So I can learn all 40 characters in a couple of days without difficulty.
Did you get through all 40 lessons at any speed ??
But I canít do anything with them even at the slowest speed.
I'm not quite sure what you mean by I can't do anything with them . . .
It would be nice to have instructions for learning the code on this site.
I will make a guess based on what happend to some other people. . .
You know all the morse characters,
you have a job recognising them when you hear them at say 18/4 ( which speed you mention ).
If so this is quite normal.
A few people learn in a very short time,
as you are building an automatic response:-
hear code - > letter pps into your head from nowhere
it can take ages for normal people - the rest of us.
How long were you expecting learning morse to take you ???
To get used to hearing the characters you can run at /2 if you need,
you should run the char speed as fast as is easily comfortable to hear,
you hear it as a single entity rather than several dits and dahs in succession.
beware of overdoing it and getting fatigue at first.
Run more 1 - 2 min sessions rather than fewer 5 minutue sessions ( for example )
You don't need to measure your speed all the time.
Listen to lots of morse. repeat repeat repeat etc
