The Random Blocks Mode generates random combinations of characters and numbers from selected sessions. This helps you practice recognizing characters in ANY order, not just memorized words!
Instead of practicing specific words like "TEA" or "TENT", Random Blocks creates random character combinations like:
- 2 chars: "AN", "T4", "E2"
- 3 chars: "NET", "5A1", "THO"
- 4 chars: "SENT", "4TE2", "HOLD"
- 5 chars: "STONE", "14T2N", "HORSE"
- Dynamic: Random length from 1-5 characters
โ No memorization - Every combination is random โ Real-world practice - Like copying random callsigns โ Character recognition - Focus on individual sounds โ Progressive learning - Select which sessions to include โ Flexible difficulty - Adjust block size and session range
- After learning characters in a session
- Before moving to next session
- To reinforce character recognition
- To prevent relying on word patterns
- To practice for contests or QSOs

All letters (A-Z) + all numbers (0-9) + punctuation + prosigns
Don't jump to full range immediately:
- Session 1 only first
- Then 1-2, then 1-3, etc.
- Master each level before expanding
Dynamic blocks (1-5 chars) are great for:
- Simulating real QSOs
- Varying difficulty
- Preventing boredom
- Testing true mastery
Alternate between:
- Random blocks (character recognition)
- Word practice (pattern recognition)
- Both skills are important!
- Lower WPM: Focus on accuracy
- Higher WPM: Build speed
- Start slow, increase gradually
Random blocks + Listening mode = Best training for real-world copying!

Notes: Need more work on "R" and "L"
Q: Blocks are too hard A: Reduce session range or block size
Q: Blocks are too easy A: Increase session range or use Dynamic
Q: Same characters appear often A: This is random! Some repetition is normal
Q: Can't recognize characters in blocks A: Go back to single-session, 2-char blocks
Q: Want only letters, no numbers A: Choose session ranges without numbers (e.g., Session 1 has no numbers)
