Hi there,
First of all become good at receiving morse, before sending too much.
If you don't have a good ear for receiving you may develop bad habits in sending which are difficult to break.
You should definitely start sending practice with a straight key.
This is the way it was taught to seagoing radio officers in my day.
Once you have good receiving speed you can then go to a semiautomatic key (bug) (dits only) or an automatic
keyer (dits and dahs), depending on your preference.
Since many modern rigs have a built in automatic keyer for use with a paddle, I would consider going this route
once your receiving speed is sufficient. Using a fully automatic keyer also means you will be sending perfect
morse, something which is not always achieved with a semi-automatic bug key.
Using a straight key is hard work and its hard to get high speeds, so eventually most cw ops go to keyers.
But remember, its hard to send faster than you can receive, since you are reading the characters as you go.
So concentrate on receiving first, then sending by straight key, then probably a fully automatic keyer with a
paddle, or a semi-automatic bug key if that is your interest.
Welcome to CW, its a great mode, and has a history of over 150 years of excitement.
