The all-in-one amateur-radio mini-games app โ 45 games across four families (Field Ops, Voice Lab, CW Arcade, Tech Bench). Phonetics, Q-codes, Morse, satellites, antennas, FCC pool, mode-ID by sight + sound, strategy sims, and a full rig simulator.
Pick the NATO phonetic word for any letter shown. Tap-only quick rounds with a streak counter and encouragement on every correct answer.
Hold the fingerprint-shaped button, speak the phonetic word out loud, release. On-device speech recognition checks your answer instantly.
Match Q-codes like QTH, QSL, QRZ, QSY to their meaning. Multiple-choice tap rounds for fast learning.
Hold and say the Q-code shown or its meaning out loud. Either is accepted โ perfect for spoken-mode practice.
Hear a Morse pattern played at your configured speed and tone; pick the matching letter from a 4-button grid.
Tap short for a dit, hold longer for a dah. The app times your taps and grades against your sensitivity setting. Uses the same circular paddle button as the QSO CW Simulator, with a feathered halo blink on every key-down.
Match a callsign prefix (W, JA, DL, F, A4โฆ) to its country from four options. Geography meets ham radio.
60-second timer mixing four pools: NATO phonetics, Q-codes, bands & meters, and amateur-radio modes & terms. Streaks of 3+ score bonus points.
Hold your phone like binoculars and physically turn yourself left or right to sweep the crosshair across the sky; raise or lower the phone for up/down. Ten named pass profiles, AOS to LOS โ sensor-fused heading means no magnetometer glitches.
Pack the right kit for the scenario โ home rig, handheld, mobile, portable, POTA, SOTA, IOTA, DX hunting, quick spot. Multi-level difficulty.
Adjust WPM, Farnsworth character speed, tone frequency, and send sensitivity from a dedicated Morse Code Settings page.
English, Arabic (ุงูุนุฑุจูุฉ), Spanish, French, German, Japanese (ๆฅๆฌ่ช), Chinese (ไธญๆ), Portuguese, Russian (ะ ัััะบะธะน), Italian. Switch instantly from Settings.
Match an amateur-radio band's meter name (160 m, 20 m, 70 cmโฆ) to its frequency range โ and vice versa. Covers 16 bands from 160 m down to 23 cm.
No accounts. No analytics. No third-party trackers. Voice processing happens on-device. Preferences live only on your phone. If the app does hit an unexpected error a one-tap EMAIL prompt lets you mail the captured event details to support โ background network noise is filtered out so only real app errors are reported.
Full theme parity in light and dark modes. Sibling-matching design language with the rest of the Unixeer Ham apps.
Quick-fire MC quiz on amateur-radio modes and abbreviations. CW, USB, LSB, AM, FM, SSB, APRS, FT8, FT4, JS8, PSK31, RTTY, SSTV, EME, D-STAR, DMR, C4FM, WSPR, SWR, ERP, ARES, RACES, Yagi, Balun, and many more โ 40 entries in total.
A full virtual transceiver across 14 bands: 23 cm, 70 cm, 2 m, 6 m, 10 m, 12 m, 15 m, 17 m, 20 m, 30 m, 40 m, 60 m, 80 m, 160 m โ all three WARC bands included. Drag the weighted VFO knob to tune โ flick it fast and it coasts under inertia (real-rig flywheel feel) so you can spin across a band quickly. Switch CW / LSB / USB / FM / AM / DIG, fine-tune with RIT (ยฑ2 kHz), pick the right filter width (NAR / MED / WID โ wrong filter or wrong mode blocks the lock-in). A live spectrum waterfall scrolls below the LCD with background noise, ghost-station traces, and a centred red TX-bandwidth strip while PTT is held. Press and hold PTT to actually talk: on-device speech recognition transcribes you live on the LCD, mic-level drives the red waterfall intensity AND the S-meter bar height in real time (silence โ 1 bar, peak voice โ 13 bars). On release, the locked voice-mode ghost answers contextually based on what you said โ signal report, name+QTH exchange, antenna talk, rig talk, weather, sign-off, or a generic reply (~80 distinct lines). CW lock-ins play real Morse; voice-mode lock-ins play from a 112-clip TTS library spanning CQ calls, DX, contests, POTA / SOTA, ragchews, nets, sign-offs, digital-mode chatter, and more.
Practice the 4-step QSO protocol with on-device speech recognition. Random role each round โ you call CQ or a fake station does. Top of screen: four progress boxes turn green โ on correct execution, red โ on miss. Wide vocabulary: 59 / five-nine / 599 / Roger / QSL / 73 / good DX / cheers โ many real on-air phrasings all count. Accepted variants are shown beneath the prompt so you always know what works. The fingerprint hold-button blooms a soft feathered halo while you speak, so you always see at a glance that the mic is open.
Same 4-step QSO protocol โ but you tap Morse instead. Each step accepts any of several real-world CW shorthands (CQ / K / KN / 5NN / 599 / R / QSL / TU / OP / FB / 73 / 88 / GL / GB / SK / EE). The fake station's replies play in real audible Morse between steps. The paddle button blooms a soft feathered halo on every press so each dit and dah leaves a quick visual blink. Pairs with the Voice simulator; both share the same progress-box UX and the Morse Send game shares the identical paddle button.
Random multiple-choice questions across the full US FCC pools โ Technician, General, and Amateur Extra combined into one stream. Pool badge shown for learning context (T / G / E). Sourced from NCVEC (public domain) via russolsen's Apache-2.0 JSON conversion.
Random metric-length antenna math across the full band catalogue. Variants: ฮป, half-wave dipole, quarter-wave vertical, 5/8 lambda, full-wave loop, and Yagi-Uda reflector / driven / director element lengths. Distractors are real lengths from other formulas, so wrong answers stay plausible.
A virtual HT face. Real repeater listing โ callsign, frequency, offset, CTCSS tone. Dial in the right TX shift direction and the matching tone from a 19-entry CTCSS chart. Tests the everyday gotchas: โ600 kHz on 2 m, +5 MHz on 70 cm, simplex on 146.520 MHz.
12 SSTV modes (Robot 36/72, Martin M1/M2, Scottie 1/2/DX, PD-50/90/120/180/240). Real VIS-code audio + spectrogram waterfall + side panel that fills row-by-row as the picture is "received". Audio auto-plays the moment you open the page and again on every new round โ no more silent first scenario.
13 modulations rendered as a drifting oscilloscope trace; pick AM/FM/SSB/CW/PSK/FT8/RTTY by sight in Waveform Lab. Listen to the same modulations by ear in Mode by Ear. Identifies every common ham mode.
Pile-Up Master is the DX operating sim โ a TTS-spoken callsign blasts through, you log it from 4 candidates. Doppler Sat is a satellite-tracking pass with a rotary knob โ compensate the right doppler shift per band (2 m SSB, 70 cm SSB, 23 cm, 10 GHz).
Six interactive tools tabbed together: SWR Tuner, Power-Loss Calculator, Ohm's Law triangle, ฮปโf converter, Solder Station (temperature + hold time), L-Network three-dial impedance match. Every slider has +/- buttons.
Virtual antenna analyzer. Pick from 6 antenna families (1/4-wave Vertical, Half-wave Dipole, End-Fed Half-Wave, Full-wave Loop, Yagi-Uda with element-count slider, Magnetic Loop with loop-diameter slider). Tune length, mounting height (image-theory ripple in feedpoint R), wire gauge (drives the dip's Q + width), radial count + radial droop angle, ground quality (salt water โ desert), and a matching network picker (None / L-match / Pi-network) that re-shapes the dip floor. Real-NanoVNA SWR sweep + live R / X / |Z| / return loss / phase / |ฮ| readout.
Dynamic-element Yagi (2โ8 elements). Tune reflector / driven / director length ratios + boom spacing โ the simulator draws the actual summed-current pattern, so beamwidth + side lobes + F/B all emerge from the math. Snap-NBS button drops to canonical proportions. Boom-length-derived gain follows Lawson's empirical curve.
Slotted circuit completion across 25 circuits in 7 workshops (RX, TX, PSU, Audio, Antenna, Filter, Digital). The parts palette is workshop-aware โ a PSU circuit won't offer "mic", an antenna tuner won't offer "speaker". Examples: crystal set, superhet IF, T/R switch, bridge rectifier, L-match tuner, 555 timer.
Three strategy sims. Contest Manager โ 12 ticks of band-hopping for multipliers. DXpedition Planner โ pick a rare entity, allocate gear budget, run a 30-second pile-up. Field Day Strategist โ pick class, allocate hours, score by the real ARRL formula.
EmComm Net teaches the NTS check-in flow under directed-net pressure with TTS-spoken Net Control prompts. ADIF Logger tests which canonical ADIF tag holds which QSO field โ foundational logging literacy for LoTW, QRZ, ClubLog.
Five-era repair sim โ 1950s tube AM-FM, 1970s transistor pocket, classic tube transceiver, modern HF SDR-class rig, SDR dongle + PC. 30 component readings; one shows the canonical fault. Replace the part, then pick the right alignment tool (sig-gen + VTVM, scope, RF tracer, ear, SWR meter, NanoVNA) โ the wrong tool tells you nothing useful.
An on-screen mascot peeks from the bottom-right of every game. Cycles between waiting, happy, surprised, and not-proud expressions in sync with the encouragement TTS. Follow That Satellite gets its own scout illustration holding the rotating Yagi.
Three foundational-electronics quizzes. Resistor Codes now spans 7 formats: 3-band (vintage), 4-band (standard), 5-band + 6-band (precision + temp coefficient), SMD 3-digit, SMD 4-digit, and EIA-96 SMD codes. Capacitor Codes: decode the 3-digit ceramic format. Symbol Quiz: recognise 12 schematic symbols.
Three new component-focused games (May 2026). Fault Lab: read a real-world symptom (120 Hz hum, S 9 with no antenna, FT8 not decoding), pick the failing part. Cap Picker: for each circuit role (PSU smoothing, RF coupling, snubber, IC decoupling, timing, tank), pick the right capacitor type + value + dielectric. Transistor Match: match a real part number (2N3904, IRF610, MRF150, NE555, LM358, Si5351) to its function.
Encouragement audio is now tuned to a teenage-male scout voice that matches the mascot โ pitch 0.90 with a wide male-voice fallback list (Daniel, Aaron, Alex, Fred, Arthur, Rishi, Reed, plus platform Siri voices). When no male voice is installed the engine drops the pitch to 0.70 to keep the timbre masculine. Rig Simulator QSOs now alternate between a male-leaning operator (pitch 0.65 โ 0.85) and a female-leaning operator (pitch 1.10 โ 1.30) so each conversation feels like a real mixed-gender pile-up.
The Doppler Trim knob grew from 110 px to 150 px so the rotation indicator is clearly visible while spinning. The horizon strip now also includes 70 procedurally-placed twinkling stars seeded once per build, so the constellation stays stable while individual stars modulate brightness with the pass clock.
