INI Configuration Reference

The daemon reads wsprrypi.ini for its execution parameters. In normal use, configure Wsprry Pi through the web interface; edit the INI file directly only when a setting is not exposed there or a development workflow requires it.

The installer stores the configuration in the user data directory:

$ ls -al /usr/local/etc/wsprrypi.ini
total 12
drwxr-xr-x  2 root root 4096 Feb 18 14:51 .
drwxr-xr-x 10 root root 4096 Sep 21 19:02 ..
-rw-rw-rw-  1 root root  171 Mar  6 19:47 wsprrypi.ini

The file uses standard INI syntax with eight sections: Meta, Operation, Calibration, GPIO, Si5351, WSPR, CW, and Band GPIO. Blank lines and extra whitespace are ignored. Each setting is a key/value pair separated by an equals sign, and comments begin with a semicolon (;).

After editing, confirm the syntax and values before restarting Wsprry Pi or relying on the configuration for transmission.

Configuration Areas

• Runtime and Service Settings covers [Meta] and [Operation], including mode, service ports, transmission gating, and control GPIOs.

• Calibration and Transmitter Backends covers [Calibration], [GPIO], and [Si5351].

• WSPR Settings covers station identity, frequency, reported power, planning, and random offset.

• CW and Band GPIO Settings covers QRSS, FSKCW, DFCW, scheduling, fades, and band switching.

• Complete Default INI File provides the full copyable example and downloadable source.
