	abstract = {<p>There are currently over 4000 HAM radio stations worldwide continuously transmitting and receiving beacon signals using the WSPR RF modulation format.\&nbsp; WSPR is implemented in the open source WSJT-x application program authored by Nobel Laureate Joe Taylor and a large group of contributors. Recent software enhancements to WSJT-x and newly available low-cost transmit and receive hardware using GPS disciplined oscillators permit records of these transmissions (known as {\textquoteleft}spots{\textquoteright}) to be used to study ionospheric events like Travelling Ionospheric Disturbances. Records of those 3 million+ receptions per day are publicly available to all researchers and citizen scientists in a SQL database which ensures access for all. In this presentation we give an introduction to WSPR, the publicly available databases where the {\textquoteleft}spots{\textquoteright} are stored.\&nbsp; Also included are websites with text, map and graphical outputs which allow easy queries about {\textquoteright}spots{\textquoteright} and examples of low cost research quality transmitters and receivers which are in operation.</p>
