QBlitz is here! Our new Q-group quick trainer helps you learn the most important Q codes for amateur radio testing and daily radio operations – interactively, playfully and with a scientifically based learning method.
What are Q-Codes?
Q-Codes are international abbreviations used in amateur radio to efficiently communicate common questions and statements. From QTH (location) to QRZ (who is calling me?) to QSL (confirmation of receipt) – these codes are an essential part of the radio language and also exam material for aspiring radio amateurs.
Six training modes
Learning
Flashcards with spaced repetition – the proven learning method that makes optimal use of your brain. Maps are scheduled based on your progress: from instant replay to 30-day intervals for codes mastered.
Quiz
Multiple choice questions in three variants: Code to Meaning (QTH → “Location”), Meaning to Code (“Location” → QTH) or Question to Code (“What is your location?” → QTH).
Lightning
Time pressure training against the clock! Choose between 30, 60, 90 or 120 seconds and collect points with combo multiplier for consecutive correct answers. Perfect for improving your reaction time.
Check
Exam simulation with only exam-relevant Q codes. No hints, no mnemonics – just like the real exam. 70% correct to pass.
Opposites
Train opposite pairs such as QRM/QRN (disturbance types), QRO/QRP (performance levels) or QRS/QRQ (speed queries). These pairs are often confused in the exam!
