SmartHamClub is an all-in-one app for amateur radio operators and learners. It combines license exam study, satellite tracking, real-time DX spot monitoring, SSTV/CW decoding, and locator tools in one place. Whether you are preparing for an exam, tracking amateur satellites, or practicing daily radio operation, SmartHamClub gives you practical tools built for real ham radio workflows. 1. Amateur Radio Exam Study In simple terms: Study with built-in Class A, B, and C question banks, review wrong answers, save favorites, and take mock exams. Technical features: The study system is built on structured local question-bank data with progress tracking, error review, favorites, randomized answer options, and simulated exam scoring. Explanations support rich text and formula rendering for radio, electronics, and regulatory content. 2. Amateur Satellite Tracking In simple terms: Check satellite position, elevation, distance, next pass time, and visibility to know when a satellite may be workable. Technical features: Satellite position and pass windows are calculated from TLE orbital data using the SGP4 propagation model. The app combines orbital prediction with device location to compute azimuth, elevation, range, AOS/LOS, maximum elevation, and current pass status. 3. Satellite Frequency and Doppler Support In simple terms: View uplink and downlink frequency information and understand how satellite motion affects radio frequency. Technical features: The app combines transmitter metadata, uplink/downlink bands, and relative radial velocity to estimate Doppler shift, providing useful references for satellite communication, monitoring, and signal decoding. 4. SSTV Image Decoder In simple terms: Use the iPhone microphone to receive SSTV audio and reconstruct slow-scan television images. Technical features: The decoder is built around real-time audio capture, frequency demodulation, filtering, pixel buffering, and multi-mode SSTV image rendering. It includes decoding support architecture for common modes such as Robot, Martin, Scottie, PD, Raw, and Fax. 5. CW Morse Code Tools In simple terms: Practice Morse code and use the microphone to help decode CW audio. Technical features: CW decoding uses audio capture, Goertzel tone detection, timing analysis, and Morse codebook matching. A CW study quiz is also included to help users learn characters, rhythm, and code patterns. 6. HamSpot Real-Time DX Monitoring In simple terms: View live DX spots across common operating modes and quickly see what is active on the bands. Technical features: DX spot data is fetched from online sources, parsed, sorted, and displayed with local time conversion. Mode filters include SSB, CW, RTTY, FT8, and FT4. 7. Maidenhead Grid Locator In simple terms: Convert your current location into a Maidenhead grid locator, or convert a locator back into approximate coordinates. Technical features: The app implements bidirectional conversion between WGS84 coordinates and Maidenhead Locator formats, supports multiple precision levels, and integrates device location and reverse geocoding for clearer location references. 8. Callsign Lookup Resolves the country and region a callsign belongs to based on callsign allocation rules (with special optimization for China). 9. HF Propagation Forecast Predicts HF propagation conditions based on the current location, target location, and current space weather forecast, making HF contacts more convenient. 10. Listening Post Publishing and Query To help hams find nearby hams who are online, this feature can be used to publish listening post information and to query nearby hams who are currently listening. 11. FT8 QSO Tool Supports FT8 audio encoding and decoding, and supports automatic logging of QSOs. 12.logbook Supports offline use, export in ADI, ADX, CSV, and Cabrillo formats.

MorseTap is a professional-grade Morse code learning application designed for efficient skill acquisition and long-term retention. Technical Specifications: • International Standard: Full implementation of the International Morse Code (ITU-R M.1677-1), covering 26 alphabetic characters, 10 numeric digits, and 24 punctuation/special characters. • Bidirectional Conversion Engine: Real-time text-to-Morse and Morse-to-text encoding/decoding with configurable output formatting. • Audio Synthesis: Pure 800Hz sine wave generation via AVAudioEngine, providing accurate timing for dots (1 unit), dashes (3 units), intra-character spacing (1 unit), inter-character spacing (3 units), and inter-word spacing (7 units). • Speed Control: Variable playback from 0.5x to 3.0x base speed (base dot duration: 80ms), allowing progressive difficulty scaling. • Visual Feedback: Synchronized LED-style flash indicator provides dual-modality learning reinforcement. Learning Analytics Dashboard: • Session Tracking: Complete history of all practice sessions with timestamps, input/output data, accuracy metrics, and duration. • Letter Mastery Grid: 26-letter progress visualization. Letters are marked as "mastered" when practiced 2+ times with >80% accuracy. • Streak System: Consecutive daily practice tracking with personal best records. • Statistical Overview: Total sessions, cumulative practice time, average accuracy rate, and current streak. Data Architecture: Built on Apple's SwiftData framework with local SQLite persistence. All data remains on-device — zero network dependencies, zero third-party SDKs, zero telemetry. Platform Requirements: • iOS 17.0 or later • Universal app optimized for iPhone and iPad • Full Light/Dark mode support • No network permissions required • No user account required Ideal for amateur radio license preparation, emergency communications training, cognitive skill development, and STEM education programs.
