Is the speed you have mastered not enough to be able to make many QSOs?
To increase your receive rate, you must practice at a rate that is the limit of your ability, gradually and steadily increasing that rate (as in RUFZ, see above).
Up to approximately 15 WPM you can record the CW text letter by letter.
At more than 15 to 20 WPM, you should recognize the words and only write down the essentials (name, QTH, WX, power, antenna, etc.).
