Wifi Rig CTRL

This app allows you to remotely operate your amateur radio transceiver from your smartphone over Wi‑Fi using a Raspberry Pi as a relay server. VPN operation is also supported. --- Main Features ■ Rig Control • Change frequency, mode, power, squelch, and filter width in real time • Supports Hamlib‑compatible rigs (YAESU, ICOM, Kenwood, etc.) • Save and switch between multiple connection profiles ■ Audio Reception (SPK) • Stream and play received audio from your radio • Selectable sampling rates (8 kHz to 48 kHz) • Optimized for stable operation over VPN connections ■ Audio Transmission / PTT • Transmit microphone audio through your radio in real time • Supports Hamlib HTTP PTT and Wi‑Fi UDP PTT (M5Atom) • Automatically follows external PTT devices ■ CW (Morse Code) Decoder • Real‑time decoding of Morse code from received audio • Track up to 5 channels simultaneously within 300–3000 Hz • Adaptive algorithm with automatic speed tracking (independent of WPM) • Improved tolerance to audio bursts and white noise over VPN ■ CW USB Key • Supports straight keys connected via USB serial (CH340 / CDC‑ACM) • CW mode: Sends keying timing to Raspberry Pi via UDP • FM mode: Uses VOX‑based PTT control to transmit tone • Includes sidetone support ■ FT8 / FT4 (Experimental) • Real-time decoding using jt9 on the Raspberry Pi • Automatic decoding synchronized with 15-second (FT8) / 7.5-second (FT4) cycles • QSO auto-exchange (DX call mode) - Automatically handles caller-side protocol (GRID → R-SNR → RR73 → 73) - 5 selectable QSO start steps (Step1–Step5) Note: This feature is experimental. Decoding performance may vary depending on environment and signal conditions. Note: Raspberry Pi 4 or later is recommended for FT8 features. ■ APRS • Send beacons using GPS or manual coordinates • Configurable callsign, SSID, path, interval, and frequency • Supports 1200 / 9600 baud --- Requirements (Server Side) • Raspberry Pi (any model) with Hamlib REST API server • Hamlib‑compatible amateur radio transceiver • (Optional) M5Atom for Wi‑Fi UDP PTT • (Optional) USB CW key (CH340 / CDC‑ACM) --- Port Configuration • REST API: TCP 8000 • Audio Stream: TCP 50000 (configurable) • Wi‑Fi PTT: UDP 8888 • CW Relay: UDP 8889 --- Raspberry Pi Setup Initial setup only requires running the following scripts after logging in via SSH. Hamlib, Direwolf, and the FastAPI server will be installed automatically. bash setup_netwk.sh (network configuration) bash setup_fastapi_radio.sh (server setup) Setup scripts and detailed instructions are available on GitHub: GitHub: ji1ore/M5CoreHamCAT This app is ideal for remote amateur radio operation, mobile operation, and accessing your home station over VPN.
