The 19th meeting of the WWV/H Scientific Modulation Working Group was held on May 28, 2024.\  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.\  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.\  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.\  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 \>1500km.\  Installation of similar equipment at WWVH is in the works.

The WWV/H Scientific Modulation Test continues after 16 months broadcasting at minute 8 on WWV and minute 48 on WWVH.\  Initial evaluation of the recordings show promise in determining time-of-flight and other characteristics.\  Efforts have started to place a KiwiSDR receiver on Kauai for an evaluation of WWVH broadcasts similar to those made of WWV.\  The WWV ARC held the Tune In: The WWV Frequency Celebration at the beginning of March to mark the 100th anniversary of WWV providing standard frequencies.\  NIST and HamSCI presented talks on March 2,\  NIST provided tours of the Boulder and WWV facilities March 3, and The Fort Collins Museum of Discovery hosted the Tune In: The WWV Frequency Celebration open house on March 4.\  Various aspects of amateur radio were showcased including traditional HF (with a station), ARISS, ARES, satellite, HamSCI, and of course a history of WWV.
