xCluster vs Ham Satting

xCluster is a visual display of dx cluster activity built for the iPad. DX spots are received via telnet or web services and displayed in a tabular form and plotted on a map of the world. You can filter the spots by call sign or band. Spots are created using the latitude and longitude of the dx station and spotter. The program has an internal call parsing component to determine the country for each call but can use QRZ.com for more accurate location data. Lookup priority is QRZ.com with the the call parser as a backup. DX spots can be displayed on a map or in a tabular form. Alerts for specific stations, bands or countries may be set and will be highlighted in the list and on the map. A number of major telnet clusters are built in along with DXSummit and PSK Reporter. PSK Reporter will display other stations that can hear your signal. You must be running WSJT-X or FLDIGI and have it configured correctly to work. You may contact the author with questions, suggestions or issues at support@w6op.com Features: Display dx spots on a map and in a list Predefined cluster servers and websites Filter by band and call sign Set alerts for display in the list and on the map Alerts can be set by country, band and call sign Save alerts in iCloud Built in call parser if QRZ.com is unavailable Freeform cluster command input Zoom and pan the map display

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)
