SDR receiver Pico RX for DIGI modes

This is a clone of Jon Dawson's project PicoRX SDR.

But I wanted to make a simple DIGI (WSPR, FT8) receiver. This modification works with PC and WSJT-X software by one USB Type-C cable. 3.5 mm audio output is just for sound control. Audio from receiver to PC goes through USB connection.

Settings

You need to connect receiver to PC by USB cable. And select COM-port and Audio input like on the pictures below.

Or if you use FLrig software

Now you can see decodes.

Automatic WSPR decoder without GUI

This script (script/wspr_decoder.py) allows you to run automatic WSPR decoding on any single-board computer without a GUI (raspberry pi, nanopi, orange pi and etc.). The script implements band hopping and automatically sends spots to wsprnet.org. Edit the configuration file (wspr_config.json) before running.

You need to install wsjtx and python3-serial before running.

sudo apt install -y wsjtx python3-serial

You need to use the latest firmware - picorx_with_reset_cmd.uf2

Web interface for any wspr receiver. Put wspr_web.py into WSJT-X directory and write the path in the script:

WSPR_FILE = "/path_to_file/ALL_WSPR.TXT"

The web interface is available on http://YOUR_IP_WITH_ADDRESS_WITH_WSPRD:8080
