• Mock exams with scoring, full question review, and a progress dashboard (study streak, exams attempted, pass rate, per-subelement mastery).
• Hundreds of plain-English lessons on operating, rules, electronics, and safety.
• Interactive Q-codes, phonetic alphabet, glossary, and a tiered band chart.

MASTER MORSE CODE
• Koch-method trainer with adjustable Farnsworth spacing, character speed, and tone.

• Send-it-yourself paddle with a tap-key decoder and live pulse-ring feedback.

LISTEN LIVE
• Curated WebSDR receivers from around the world.
• Built-in SWL logbook — frequency and mode auto-filled from the live receiver, plus callsign, RST, and notes; export the whole log as CSV.
