Designed by Neville Marr \u2013 ZL2BNE<\/strong><\/p>\n The WSPRnator<\/strong> is a homebrew, standalone WSPR beacon designed for amateur radio operators who want to build their own low-power propagation beacon.<\/p>\n It covers amateur bands from 2200 metres through to 2 metres<\/strong>, with selectable RF output of approximately 25 mW, 100 mW or 400 mW<\/strong>.<\/p>\n An ESP8266<\/strong> provides the control and Wi-Fi connectivity, while a Si5351<\/strong> frequency synthesiser generates the RF signal. Once configured, the WSPRnator operates independently \u2014 no computer is required during normal operation<\/strong>.<\/p>\n The WSPRnator was first presented at TopFest 2026<\/strong>, where the project was introduced to the amateur radio community.<\/p>\n [ Build \u2013 Configure \u2013 Use<\/a> ]<\/strong> [ Schematic<\/a> ]<\/strong> [ Gerber Files<\/a> ]<\/strong> [ Interactive BOM<\/a> ]<\/strong><\/p>\n WSPRnator is a dedicated transmitter for WSPR \u2014 Weak Signal Propagation Reporter<\/strong>.<\/p>\n WSPR is a digital amateur-radio mode designed for very weak signals. Receiving stations around the world can automatically decode WSPR transmissions and upload reception reports, providing a fascinating way to investigate radio propagation.<\/p>\n With a WSPRnator you can build a dedicated beacon, connect an appropriate antenna, and observe how your signal travels.<\/p>\n Try different bands, antennas and power levels and see where your signal is heard.<\/p>\n The WSPRnator is for amateur radio operators who enjoy building, experimenting and learning<\/strong>.<\/p>\n It is particularly suited to people interested in:<\/p>\n It can also make an excellent radio-club construction project<\/strong>, with the PCB, components, software and construction information providing plenty of opportunities for hands-on experimentation.<\/p>\n The WSPRnator provides jumper-selectable operation across a wide range of amateur bands:<\/p>\nBuild your own WSPRnator<\/strong><\/span><\/h3>\n
