Rob Robinett AI6VN "WsprDaemon: A low cost, high performance, all band WSPR decoding system". ARRL / TAPR Digital Communications Conference, Detroit, 2019.
Presentation by Paul Elliott WB6CXC at the 2025 Hamvention TAPR Forum on 16 May 2025.
The first half is about SDRs: dynamic range, signal to noise optimization, filtering, sampling and aliasing, etc. Then Paul shares some details about the WSPRSONDE.
Rob Robinett AI6VN presents on WSPRDaemon and the Personal Space Weather Station at The University of Scranton IEEE Meeting and W3USR Open House on 24 April 2025.
