Store description excerpt

PulseModem A is the APRS client for licensed Amateur Radio operators on iPhone and iPad. Connect to the global APRS-IS network and watch nearby stations appear on a live map in real time — each one drawn with its authentic APRS symbol icon and a country flag derived from its callsign prefix. LIVE APRS-IS FEED - Connects to rotate.aprs.net with a geographic filter centred on your GPS location - Displays raw packets as they arrive, colour-coded by type - Auto-connect on launch — PulseModem A is ready before you finish your coffee - Decodes uncompressed, Base91 compressed, and Mic-E packets (common in Kenwood and Yaesu radios) INTERACTIVE MAP - Every station plotted with its real APRS symbol PNG — car, hiker, weather station, digipeater, and hundreds more - Tap any pin to see a callout; tap the callout to open the full station detail - Centres on your location at city level the moment a GPS fix is available - Your own beacon appears on the map immediately after sending STATION LIST - Full searchable list of received stations - Country flag next to every callsign, resolved from the standard cty.dat prefix database - iPad split-view: select a station on the left, see full details on the right - One tap to look up any callsign on QRZ.com — right inside the app, no browser switch GPS BEACONING - Send your position to the APRS network with a single tap - Choose your station symbol from a searchable visual grid of all APRS symbols - Add an optional comment to your beacon packet - Encoded in Base91 compressed format for maximum compatibility SETTINGS & COMPATIBILITY - Callsign and passcode stored securely in the Keychain - Upgrading from an earlier version? Your callsign, passcode, and preferences carry over automatically - Adjustable filter radius, fallback coordinates for GPS-denied environments - Supports receive-only mode (passcode -1) — no transmit license required to monitor REQUIREMENTS A valid amateur radio license is required to transmit on APRS. Anyone may receive and monitor. RF Receive and RF Transmit (direct audio-port TNC operation) are under re-development and will return in an upcoming update.
