DS1UOV's AI CW Radio is a premium radio simulation app that reinterprets the essence of amateur radio—Morse Code (CW)—through advanced AI technology. Featuring an intuitive UI that mimics real radio equipment and a phosphor green terminal aesthetic reminiscent of 80s retro computing, this app offers an experience far beyond simple practice. ■ Key Features 1. Intelligent AI Operators The app uses AI to generate dynamic QSO scenarios. AI operators recognize your code and respond contextually, providing the tension and excitement of a real on-air contact. 2. Authentic Propagation Simulation Real-world space weather indices, including SFI, SSN, and K-Index, are integrated into the app. Band availability and signal quality change in real-time, requiring users to find the best frequency for a successful QSO. 3. Precise CW Control Full support for both Straight and Paddle keys. Users can finely tune WPM and sidetone settings. The sidetone algorithm is designed to mimic real radio oscillators, reducing auditory fatigue during long sessions. 4. QSL Card System with 36 Designs Create unique QSL cards based on your contact data. A deterministic design system selects one of 36 themes based on callsign characteristics, allowing you to share your radio achievements with pride. 5. Global Leaderboard and Ranks Earn points and climb the operator ranks based on your performance. The global leaderboard provides constant motivation by allowing you to compare your skills with users worldwide. 6. Professional Log Management All contacts are recorded in a military field-style logbook. With ADIF standard support, it is easy to sync with external logging software. The stats dashboard helps you analyze your operating patterns at a glance. ■ UI and Design The app reconstructs the visual elements of VFO consoles and CRT monitors. Scanline and glow effects evoke the nostalgia of analog radios, while the layout is optimized for readability with dedicated fonts. ■ Learning and Knowledge The app provides professional knowledge required for amateur radio, from band characteristics to interpreting space weather data, helping beginners grow into veteran operators. ■ Perfect For • New ham operators preparing for their first real QSO. • Enthusiasts who cannot set up a real radio station at home. • Veterans looking to maintain their CW proficiency. • Lovers of retro technology and analog aesthetics. Whether you are preparing for your first amateur radio license or are a seasoned veteran wanting to keep your ears sharp, DS1UOV's AI CW Radio offers a sophisticated and stylish way to master the art of CW. DS1UOV's AI CW Radio is a digital sanctuary for CW enthusiasts worldwide. Dive back into the world of radio waves with AI as your new companion. The airwaves are calling. Are you ready to answer?

Thank you for using DS1UOV's AI CW Radio. In this major update, we are thrilled to introduce the highly requested CW Receiving Training modes, realistic HF audio simulation, and daily challenges to keep your skills sharp. ■ Key New Features 1. New CW Training Modes (TRAIN) Koch Method Trainer: The gold standard of Morse code learning. Start with just 2 characters; master them with 90%+ accuracy to unlock the next levels, covering up to 40 characters. Callsign Copy Trainer: A RufzXP-style drill using realistic amateur radio prefixes. The playback speed (WPM) scales dynamically up or down based on your answers, allowing you to push your copying limits. 2. Realistic HF Audio & Noise Simulation (P2) Experience the raw atmosphere of HF bands right from your device. Features realistic white noise and static crackles (QRN), slow fading amplitude based on space weather K-Index (QSB), and faint interference signals (QRM). Adjust the intensity anytime via the Settings > AUDIO > HF NOISE slider. Setting it to 0% turns it completely off for zero CPU overhead. (Your sidetone remains perfectly clean.) 3. Contest Simulation Mode (CONTEST) (Morse Runner Style) Immerse yourself in the thrill of a real CW contest pile-up. Copy overlapping stations responding with different tones, speeds, and signal strengths. Log the correct callsigns and serial numbers to score points. Track your progress and chase your own Local Personal Best score without any server hassle. 4. Daily Missions, Streaks, and Expanded Achievements Get 3 random 'Daily Missions' every day, featuring tasks like logging QSOs, operating on specific bands, or completing training runs. Keep your practice momentum going with the Daily Streak Counter displayed directly on the home screen. 9 New Achievements added (16 in total) to reward your dedication, including "Koch Graduate", "Callsign Ace", and "Contest Master". 5. Friendly Onboarding Overlay (D1) New to the app? A step-by-step 6-stage guided tour will now walk you through the core features (VFO tuning, training/contest modes, daily missions, etc.) upon your first launch. 6. Other Improvements Optimized home navigation layouts for a smoother user flow. Added 20+ localization strings for a seamless English and Korean UI experience. Update now and take your CW proficiency to the next level. 73! ### 1.0.6 — 2026-06-22 bug: Improved minor stability issues. ### 1.0.4 — 2026-06-02 bug: Improved minor stability issues. ### 1.0.3 — 2026-03-19 bug: Improved minor stability issues. ### 1.0.2 — 2026-03-19 No release notes. ## More apps by CommonSource - [SpeakEasy:AI Speaking Practice](https://appshunter.io/ios/app/speakeasyai-speaking-practice/id6478114185) - [변호사 계산기](https://appshunter.io/ios/app/id6739842840) - [Fave LED: Banner & Scroller](https://appshunter.io/ios/app/fave-led-banner-and-scroller/id6740153440) - [DS1UOV's Morse Trainer w/ Koch](https://appshunter.io/ios/app/ds1uovs-morse-trainer-w-koch/id6753097051) - [Lina Chess:Offline AI & Puzzle](https://appshunter.io/ios/app/lina-chessoffline-ai-and-puzzle/id6757314610) - [판례냠냠](https://appshunter.io/ios/app/id6757954714) All apps by CommonSource: https://appshunter.io/developer/846011481 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
