Hugh,
You may find a quick blurb about the following site gets quite a good reader reaction. As a Ham of just under five years, the best site and aid I’ve found to learn Morse code is at lcwo.net [1]. They focus on the Koch method and have several types of training courses. In just a few weeks of daily training, you’ll find that your comprehension will pick up quickly enough to start picking up operators on the air. – A Ham in Colorado
