Sending Morse code is much easier than receiving it and therefore NuMorse concentrates exclusively on helping you to receive Morse code. When you can receive code at a given speed you will be able to send at that speed with very little practice. For sending practice you will need a code key and a code oscillator and these are obtainable from all ham radio stores. A home built code oscillator would make a nice construction project if you wanted to try your hand at building your own circuits.
