    Miami, Florida. Saturday September 21, 2019.

    Today, Stefan, DK3SB, assembled, programmed and and power up tested the tracker for the first of the four launches of the MIAMI HIGH ALTITUDE CIRCUMNAVIGATING BALLOON PROJECT.

    Tomorrow, Sunday September 22nd, weather permitting, and beginning after 1300 Z, should begin testing outside GPS reception and 20 meter WSPR transmission of the tracker.

    The tracker has been programmed with call sign: K4LCD . If interested, it should show up at WSPR 20M or at a tracking platform such as https://tracker.habhub.org/#!mt=roadmap&mz=11&qm=1_day&f=NASD01&q=!RS_*;

    [7:42 AM, 9/22/2019] Stefan Biereigel DK3SB: Here's what the payload transmits, you can see make out in which slots clouds covered the sun and therefore it did not transmit
    [7:43 AM, 9/22/2019] Stefan Biereigel DK3SB: So today's testing checked that the solar charging works and the transmissions work fine.

    Thanks Stefan for your invaluable technical advice on balloons, payload design and assembly, launch methodology planning, tracking, and the trackers.

    With thanks 73,
