Ham Satting vs Echo

Track amateur radio satellites in real time, predict passes, log QSOs, hunt grid squares — with a live APRS map layer and the new Music Broadcast service. Built by a fellow ham (A41UX) — free of analytics, ads, and tracking. CORE FEATURES • Real-time tracking for FM/SSB linear birds (e.g. ISS, SO-50, etc.), digipeaters (e.g. GRBBeta, Foresail-1p, etc), SSTV + SSDV image birds (e.g. Lobachevsky, GEOSCAN 1-6 , etc.), Weather LRPT (Meteor-M N2-3 / N2-4), and Music Broadcast (e.g. BALKAN-1, Flamingo-1, etc) • Pass predictions with quality indicators (Excellent, Good, Fair, Poor), AOS / LOS, max elevation, duration, azimuth • Interactive footprint mapping with live position + great-circle bearing lines • Compass dialog with theme-aware export image and watermark • AR Tracking (iPhone / iPad) using device compass + accelerometer • Multi-satellite tracking and side-by-side pass comparison • Five-mode AR audio recording (iPhone / iPad): SSTV, SSDV, Digital, Weather, Music — Doppler-corrected RX labelling; consistent WAV naming NEW IN APRIL 2026 • Music Broadcast: 4 satellites transmit short music tones as an RF identifier instead of CW Morse — T.MicroSat-1 plays Beethoven's "Ode to Joy" on 401.025 MHz; BALKAN-1, Flamingo-1, OTP-2 use classical / video-game themes. RX-only on UHF 400-402 MHz; brown toggle on AR page records the pass. • Scheduled Service Events: register a temporary frequency override for SSTV, SSDV, Digital, or Weather (Meteor-M rotation, ARISS channel shifts, etc.) • APRS digipeater added on SONATE-2 (DP0SNX) and NO-44 (PCSAT, W3ADO-1) on 145.825 MHz simplex • IO-86 SSDV downlink added on 145.880 MHz • AMSAT Live Activity Indicator: every prediction card carries a 24-hour activity dot in AMSAT cell colors, sourced from the AMSAT Live OSCAR Satellite Status page. Tap for a 48-hour popup with individual reports per cell (callsign + grid + UTC slot), attribution, and a compact share-image. • 10 new satellites with permanent NORADs: TO-108, GRBBeta, Foresail-1p, Horizon, 239Alferov, Luca, BALKAN-1, Flamingo-1, OTP-2, T.MicroSat-1 • APRS Live Map Layer: read-only APRS-IS feed, age-fading trails, 40+ symbol mappings, SSID filters, heard-by via aprs.fi • SSTV Decoder: multi-mode (Robot 36, PD 120 / 180, Martin, Scottie, Wraase, AVT, etc.) • Q1 2026 batch: 8 new satellites added (HADES-SA, PARUS-T3, HYPERVIEW-1G, MAGNARO-II Piscis, ARICA-2, FSI-SAT2, ZERO-II, OrigamiSat-2) • UI: long sat names auto-fit at any Font Scale; filter pills always one row; (i) info icons; 125 in-app tips LOGGING + AWARDS + EXPORT • Full QSO logbook: callsign, grid, mode, freq (TX / RX), satellite, RST, distance, bearing • Grid Hunters VUCC tracking with worked-grids map + great-circle paths from QTH • Per-QSO QSL card export — themed PNG ready to share or print • Export to ADIF (LoTW / TQSL), JSON, or CSV • Maidenhead 4 / 6 / 8-character grids • DXCC + VUCC dashboards, distance + bearing stats, worked-by-band charts • Calendar integration; smart pass notifications with min-elevation filter TECHNICAL • Available on iPhone, iPad, and Mac (Apple Silicon + Intel). AR Tracking and live audio recording are iPhone / iPad features; pass prediction, logging, exports, mapping, and the AMSAT indicator run on every Apple device. • N2YO API for orbital data (free key required for non-ISS satellites) • Cached satellite catalogue works offline • Privacy-first: data stays on device, no analytics SDKs, no advertising IDs, no tracking. APRS-IS, N2YO, AMSAT Live OSCAR Status, and the optional aprs.fi REST are the only network calls PERFECT FOR • Amateur radio operators pursuing satellite communications • AMSAT members and CubeSat / PocketQube enthusiasts • Contest participants and award hunters (DXCC, VUCC, satellite awards) • SDR listeners curious about Music Broadcast on 400-402 MHz 73 — A41UX (Unixeer, Oman)
