Analyse de l'application SVXConnect pour le 5 août

SVXConnect is a push-to-talk voice client for the SvxLink amateur radio reflector network. It lets licensed operators join talkgroups, monitor multiple groups at once, and transmit voice over IP — all from an Android phone, no extra hardware required. Designed for amateur radio operators SVXConnect is intended for licensed amateur radio operators. You connect to a reflector you have access to, identify with your call sign, and exchange Opus-encoded voice with other operators on the network. On first connection the app generates an RSA key and certificate signing request on your device; the sysop signs it and your client certificate is then used for every future session. Features • Push-to-talk voice with on-screen button (tap-to-toggle or press-and-hold, selectable in settings) • Talkgroup switching with a configurable favourites list • Monitor multiple talkgroups simultaneously, with priority preemption • Live activity view of who is talking on which group • Reflector map showing nearby nodes (OpenStreetMap tiles, no API key required) • Automatic location reporting (GPS via Google Play services, with manual override) • Home-screen widget for one-tap Connect / Disconnect / TG select (phone and tablet) • Picture-in-Picture mode — keep the connection status and current talker visible while using other apps • Foreground audio service so transmission keeps working when the screen is off • Opus codec for clean low-bitrate audio • AES-128-GCM and HMAC-SHA1 authentication for the protocol layer • Compatible with the standard SvxLink reflector protocol and the enhanced WebSocket feed used by RF.Guru reflectors Push-to-Talk over Cellular (POC) support If you use SVXConnect on a ruggedised POC radio, the hardware PTT button and (where present) channel selector, man-down / emergency, and side keys are picked up automatically through each vendor's public broadcast — no additional configuration required. Verified devices include: • Hytera P60 — PTT + channel up/down + man-down "panic TG" mode • Samsung XCover — top / bottom hardware buttons via Knox's unmanaged-key-mappings framework • Uniwa F400 Optimised for small screens POC handset owners with 320-dp-class displays (Hytera P60 etc.) get a dedicated tight-layout mode, an auto-hide bottom navigation bar (swipe up to reveal), and a hide-on-screen-PTT toggle so the whole screen can be devoted to talkgroups and the activity feed. Optional TTS callouts announce every talkgroup switch for mobile / driving operators. What you need • A licensed amateur radio call sign • Access to a SvxLink-compatible reflector (host, port, and sign-off from the sysop) • An Android device running Android 12.0 or later Privacy SVXConnect contains no advertising, no analytics, and no third-party tracking SDKs. Audio is captured only while you press the PTT button and is sent directly to your configured reflector — never recorded or stored. Your call sign, certificate, and settings stay on the device. Location is shared only with your reflector (for the map view) and, as a fallback, with ipwho.is when GPS is unavailable. The full privacy policy is linked from this listing. Acknowledgements SVXConnect is built by RF.Guru. The protocol implementation interoperates with SvxLink, which is the work of Tobias Blomberg (SM0SVX) and contributors. Map tiles are provided by OpenStreetMap. Opus codec support uses Concentus, a pure-Java port of libopus. Contact Questions, bug reports, or sign-off requests: https://svxconnect.app
