	abstract = {<p>The 19th meeting of the WWV/H Scientific Modulation Working Group was held on May 28, 2024.\&nbsp; The topic of discussion centered on WSPR with Rob Robinett, AI6VN, giving a presentation on his software, WSPRdaemon, and the potential for the WSPR network to contribute to HamSCI efforts.\&nbsp; After discussion, it was decided that installation of a WSPRsonde transmitter manufactured by Turn Island Systems and Paul Elliott, WB6CXC, would be pursued at both WWV and WWVH transmitter sites.\&nbsp; Dave Swartz, W0DAS, conducted the initial installation at WWV/B over the summer and fall months of 2024 with extensive help from the NIST WWV/B staff, and details will be discussed.\&nbsp; Early analysis of the WSPR data was very encouraging, with the 1-watt signal sharing very similar Doppler shifts with its 10,000-watt counterpart, as reported from a station at \&gt;1500km.\&nbsp; Installation of similar equipment at WWVH is in the works.</p>
