Learning Tips

1. Start Simple

Begin with simple characters like E and T, then gradually learn complex ones. Practice 10-15 minutes daily for best results.

2. Audio Memory

Learning through sound rhythm is more effective than visual symbols. Use audio practice tools for repeated listening exercises.

3. Practical Application

Try applying in daily life by sending simple words. Join amateur radio communities for more practice opportunities.
