Hi,
Head copying, ok, I describe it how I learned it myself.
For me it was a slow process but it developed automatically.
There are 4 seperate areas:
The very short SOTA and contest qso type.
The normal qso
The ragchew qso.
Call signs
Short and normal qso: all that info that comes often, example wx, name, qth and so on you learn to understand automatically, simply by using it and listening, after some time you hear things like 73, rst, 5NN without even realising,it comes like normal speach.
A ragchew qso is something completely else, you need training + a lot of qsos for that.
I give an example how to learn the 100 most common words in English: a link:
There is a series there where you can switch to the 500 most common words.
Call sign recognition: an example: the cw freak net, there you can learn and go into competition with operators in the whole world.
