This is often neglected or glossed over in the literature that is available but is just as important as knowing the code itself if meaningful contacts are to be made.
I would suggest learning from the random QSOs generated by MorseGen first, once you know Vlad, Ann and the others intimately and are getting so good you are anticipating words and the structure of the QSO then move onto the random QSOs generated by G4FON which are much longer and verbose with several strutural changes which are good to progress to.
Listen on air and see how bad some CW is sent - and realise you don't have to be a perfectionist to pound the key!
Learn the Q code as much as you can. Compile a template of standard QSOs.
See which callsign is sent first, always the other stations out of courtesy - and so they know to expect your callsign that they might not have copied 100% first time.
Get used different terminlogy for the same thing, I've heard all these and more:
1. How are you copying me?
2. HW is my cpi?
3. HW copy?
4. HW cpi?
5. HW?
We could do the same for QTH, QSL etc.
Listen, listen and listen again.
Read the guidance from the masters and get prepared for that 1st outing in the air.
If you can start on 40 or 80m, the higher frequency bands are great but they are generally have more high speed operators searching for DX than the more patient operators who will be more tolerent of your nerves and mistakes you may make.
I'm sure your first few QSOs will follow a template and you will breath a sigh of relief when they are over, and hopefully want to carry on! Soon you will be adding a few variations, you will pick up other operating techniques you like that you didn't hear on the practice programs.
Going solo without a script is terrifying but I did this on 80m and explained it to the other operator, I got real encouragement, congratulations and one of the best QSL cards - it was no DX being a G station but it meant more to me than anything.If I had done that on 30m I would probably have heard '73 OM' pretty soon, those boys want contacts!
I'm still learning, I still drop a dit off my 6 occasionally and I always blame the paddle (the gold plate must have worn off!). My ventures on the higher bands are more successful and confident.
After reading this it may appear daunting - it is BUT DON'T PUT IT OFF!!!! Get on the air and enjoy the challenge of having one of the ultimate skills - conversing in morse code with radio waves - cool eh?
