Command Line Options

Wsprry Pi normally runs as a systemd service. Use these pages when you need shell-based testing, calibration, direct WSPR or CW transmissions, hardware backend selection, or service controls.

Start with Command-Line Quick Start before running a manual command. It explains how to stop the managed service safely and shows the supported command forms. For ordinary day-to-day configuration, use the User Interface.

Topics

• Command-Line Quick Start covers the managed service, CLI forms, common examples, and direct WSPR positional arguments.

• General and WSPR Options documents common process controls, repeat behavior, offset selection, and WSPR message planning.

• Transmitter Backend Options distinguishes direct GPIO RF output from the Si5351 clock-generator backend.

• CW Mode Options documents QRSS, FSKCW, and DFCW message, frequency, timing, spacing, and envelope controls.

• Service, GPIO, and Test Controls covers web and socket ports, indicator and shutdown GPIOs, test tones, and operational qualifications.
