DS1UOV’S MORSE TRAINER
A modern Morse code training app built around the Koch method for structured, measurable improvement in Morse reception skills (no AI-versus mode is included).
1. KOCH METHOD PROGRESSION
Train with a small set of characters first, then expand step by step as your accuracy proves you are ready.
Level advancement is performance-based, helping you avoid guessing and build reliable recognition.
2. PROGRESS DASHBOARD AND LEVEL SELECTION
See your current level, your highest unlocked level, and overall completion progress in a clear visual overview.
Select any unlocked level to review, reinforce earlier characters, and stabilize performance before pushing forward.
3. CUSTOM PRACTICE SETTINGS
Adjust session settings to match your skill and listening comfort, including tone frequency options and speed-oriented configurations.
Use built-in presets (beginner through expert) to start quickly with sensible defaults.
4. FOCUSED TRAINING UI
During active practice, track remaining time and progress with a clean, distraction-free layout that supports pausing and resuming.
Enter answers using a dedicated character input grid that is automatically limited to the characters available at your current level.
Physical keyboard input is supported, enabling more realistic practice on tablets or when using external keyboards.
5. DETAILED RESULTS AND ERROR ANALYSIS
After each session, view accuracy (%) with clear feedback on whether you met the advancement threshold (90% for unlocking the next character when you are at your max unlocked level).
Review side-by-side comparisons of transmitted text versus your typed input to spot exactly where errors occurred.
Inspect mistake statistics that highlight commonly confused characters, so you can target weaknesses with intention.
Quick actions let you retry the current level, return to the home screen, or continue with the next newly unlocked character when eligible.
6. RESET OPTIONS AND CONTROL
Reset only your Koch training progress (restart from level 1 while preserving settings), or reset all settings back to defaults when needed.
If you want an efficient, disciplined path to Morse proficiency with real feedback and clean progression, DS1UOV’s Morse Trainer is designed for daily practice and steady gains.
