HamSCI Speaker Series Explores WSPR Spectral Width

HamSCI's first Speaker Series of 2026 will be presented by Dr. Barry Johnson (W4WB) and focus on WSPR spectral width.

Johnson will be speaking on a paper he co-authored along with Gene Marcus, W3PM titled “A Modest Study of WSPR-2 Spectral Width”. The topic arose from a question posed originally by HamSCI scientist Gwyn Griffith G3ZIL, which was, “What is the minimum obtainable spectral width of WSPR-2 signals?” To answer this seemingly simple question was anything but simple, as will become evident in the discussion comprising this presentation.
