wspr-beacon

Open source, multi-user SDR receiver software with a web interface

A compact hardware device for transmitting WSPR messages based on the SI5351 clock generator, using GPS for transmission timing synchronization and automatic QTH locator calculation.

WSPR beacon based on Arduino + si5351

Band hopping WSPR beacon for Arduino and Si5351

Si5351 based WSPR beacon

WSPR receiver on Raspberry PI

High Altitude Balloon tracker for Arduino and Si5351, using WSPR protocol and Morse code.

A WSPR beacon that uses novel techniques to control an Si5351 for mHz frequency control even into the UHF range.

A multimode radio beacon for QRSS (FSK-CW, CW) and WSPR. Implemented using AD9850 and STM32duino. Repository hosting schematics, software and other implementation notes.

Graphical plots for amateur radio WSPR hf performance using propagation accuracy measurements

Program for reporting activity of WSPR based on rtlsdr-wsprd logs.

APRS LoRa+ is an all-in-one multi-mode tracker for amateur radio operators (supporting APRS LoRa, APRS FSK, CW, WSPR, FST4W, FT8, FT4, LR-FHSS and DAPNET), designed for portable use—such as in the mountains, while sailing, or out in the field—including SOTA/POTA QRP activations

Alternative firmware for Traquito JetPack WSPR Beacon

A C++-ified and modernized restructuring of JTEncode code that has been forked many times by various hams. This is built for now as part of an ESP-IDF (ESP32C3) test.
