PSK Reporter is an amateur radio signal reporting and spotting network and website started by Philip Gladstone in 2014 which allows operators to see where their radio signals are being received.[1][2] The platform works by collecting digital signal reports from software clients such as WSJT[3] and FLDIGI,[4] then mapping them to show which stations are being heard by other clients.[5][6] The website takes its name from the popular amateur radio digital mode PSK31 and supports numerous digital modes,[7][8][9] but now the vast majority of digital modes recorded by the service are FT8 traffic.[10] Most traffic recorded on PSK Reporter is in the HF amateur radio bands but the platform also supports MF, VHF, and UHF bands.[11][12] As of 2021 PSK Reporter had collected over 20 billion reception reports.[13]
