Ham Satting

Amateur Radio Sat Tracker

Free

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)

Rig and rotator control: Ham Satting can now tune your radio and point your antenna for you. RIG CONTROL (CAT) - Track a pass with a radio connected and both VFOs stay Doppler-corrected for the whole pass: uplink pre-compensated, downlink corrected, hands-free. It also sets the satellite mode and sends the CTCSS tone the FM birds need. - It tunes your radio. It never transmits — keying stays entirely in your hands. - Turn the dial yourself and the app notices within a second and stops fighting you. - Eight ways to connect: rigctld, Icom WLAN (CI-V over UDP), Kenwood KNS, Elecraft K4, serial over TCP, the IC-705's Bluetooth LE, a BLE-UART bridge, or TCI (WebSocket) for Expert Electronics SunSDR2 and MB1. - Around 90 radio models in a searchable picker, each with its CI-V address, baud and driver filled in. ROTATOR CONTROL (new) - Points your antenna at the satellite for the whole pass — azimuth and elevation — then parks it where you choose at LOS. - Speaks rotctld, GS-232, Easycomm, SPID, DCU-1 / Rotor-EZ / Green Heron RT-21, Prosistel and M2 RC2800, over the network or a serial-over-TCP bridge. Azimuth-only rotators work. - You declare the travel limits and where azimuth zero sits, because only you can see the mast. It reads the position back, so it never drives blind. Both are off by default and marked Experimental. With nothing connected the app behaves as before. On iPhone and iPad, on the AR tracking page. SSTV DECODER - New Auto (VIS) mode, now the default: the app reads the header the transmitter sends and picks the mode for you — no need to know whether the ISS sent PD 120 or Robot 36. - Nine modes that were listed but never really worked now decode for real, including Wraase SC2-180 and Scottie DX. Twenty modes are offered and all twenty decode. - PD colours fixed — including PD 120, the mode the ISS uses — and Robot 72 and Robot 36 colour timing corrected. - AVT 90 and AVT 94 removed: their timings cannot be established from any reliable source. MAP, LOG AND APRS - Your height above sea level now shows on the map details strip, looked up from a terrain model rather than the receiver's own altitude, which is the least accurate figure GPS gives and drifts while you stand still. - APRS now proves a satellite contact: a packet repeated by the ISS shows the relaying station under "RF heard by". A Doppler sign error that put the Digital uplink 10 kHz off on the wrong side — so packets never got in — is fixed. - ADIF, CSV and JSON exports name the space station ARISS, and write band and frequency as a pair or not at all, so a logging service can no longer refuse a whole upload. - The dark basemap has a new source: the old one began stamping "API KEY REQUIRED" across every tile. HAMS.AT - Announce your own activation: pick a satellite, find your passes, choose one, and the app posts it for you. Needs your own Hams.at API key. Reading the list still needs no account. - The Hams.at page now loads — it goes through the phone's native networking, which completes the TLS handshake the app's own stack could not. CATALOGUE - ISS SSTV is on 437.550 MHz and ISS APRS on 437.825 — the Zvezda 2 m radio is down per ARISS. The app follows the working frequency. - New: MARINA, KOSTKA, Scorpion, SamSat-Ionosphere, CubeSX-HSE-3. Retired: D-STAR ONE Sparrow and iSat, HYPERVIEW-1G, PARUS-T2, HO-113. - A large batch of invented frequencies is corrected: 56 satellites all claimed the same 145.900 uplink with the same 67 Hz tone, which is impossible. 46 are fixed, and 20 satellites you could work but not log join the QSO list. FIXES - On macOS, "Add to calendar" and saving the user manual really do reach your Downloads folder now. - Fixed three crashes that could happen after leaving a page, and a pass followed from Sat Match no longer gets a length of zero. 73 de A41UX
