Today 1600 UTC: Amateur Radio meetup - Studying the 2017 Solar Eclipse

[Derek Kozel]

    Hello
      folks,
    
    A
      quick note that today's Amateur Radio meetup is John Ackermann
      N8UR sharing his experience of recording the HF spectrum during
      the 2017 Solar Eclipse and showing the Hermes & Red Pitaya
      SDRs, HDF5 format data capture, and scripts for post-processing.
    
    Meetup and talk is May 8th at 1600 UTC (3 hours from this email)

    "The total solar eclipse in August, 2017, was the first opportunity
    for the "HamSci" community to get crowdsourced ionospheric data,
    looking for propagation changes as the eclipse occurred. There were
    several HamSci activities that weekend, including an Eclipse QSO
    Party. A number of hams monitored the bands looking for changes in
    frequency or amplitude as local totality approached and went.
    
    I used SDRs and GNU Radio from my location in northern Michigan to
    record the entire 80, 40, 30, and 20 meter bands, as well as the
    entire AM broadcast band, for 8 hours. The result was nearly 1 TB of
    data.
    
    I'll show the equipment configuration, some of the GNU Radio tools
    used both to capture and post-process the data, and some results of
    the experiment."
    
    Sorry for the short notice.
    
    Cheers,
    Derek
