Effects of the April 8, 2024 total solar eclipse upon reception of North American signals in the medium-wave broadcast band, using software defined radio files recorded in Lewisville, TX, USA, Part 2

Recorded by:  Greg Thompson.

Grid square of location recorded:  EM13lb

Maximum obscuration of the sun was  100% at 1843UT on 8 April 2024.  

These data files are recordings of the entire medium wave broadcast band (535-1705kHz) made during the total solar eclipse of 8 April 2024 from 1615 to 2115UT from Lewisville, TX, USA.  

Data Quality: Only limitations are short data dropouts (< 20 sec), 4 per hour after 1800UT, plus a few spurious carriers

Data files are .wav format, but the archived files are .zip, with about five .wav files packaged together in each .zip file, using the prefix “GThompson-wideband_500_1750kHz_“. As the total files recorded during the solar eclipse exceeded the Zenodo 50GB limit, the remainder of the dataset is found in "Effects of the April 8, 2024 total solar eclipse upon reception of North American signals in the medium-wave broadcast band, using software defined radio files recorded in Lewisville, TX, USA, Part 1”.  Please see that record also for software and for supporting documentation.

Antenna:  MLA30 loop @ 30  / 210  degrees.

Receiver:    SDRPlay RSPDx; 85% max RF gain setting, with center frequency 1125kHz, recording a 1250kHz wide passband, using SDRuno software.   Hardware was not locked to a frequency standard; receiver was calibrated to WWV.
