Effects of the 2024 total solar eclipse upon reception of trans-Atlantic signals in the medium-wave broadcast band, using software defined radio files recorded in Sfax, Tunisia.

Recorded by: Ashraf Chaabane, 3V9A. Grid square of location recorded: JM54iq Maximum obscuration of the sun was 0%, as the eclipse ended in the North Atlantic Ocean, west of the recording site. However, unusual signals were noted from North America during the eclipse period. 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 1915 to 2055UT from Sfax, Tunisia. They are part of a set of such recordings made from 1814UT on April 8th, 2024 to 005UT on April 9th, 2024 and 1814UT on April 9th, 2024 to 0005UT on April 10th, 2024. Data Quality: Only limitation is a bit of thunderstorm static, otherwise good. Data files are .wav format, but the archived files are .zip, with three or four .wav files packaged together in each .zip file, using the prefix “3V9A-wideband_305_1905kHz_ “. The recordings not included here are available by contacting HamSCI at [e-mail], if you require this data. Antenna: 100m wire at 320degrees, no termination. Receiver: Perseus, 0dB front end attenuation, with center frequency 1105kHz, recording a 1600kHz wide passband, using Jaguar Pro software. Hardware was not locked to a frequency standard; Bodnar GPS locked frequency standard at 1705kHz was used as reference for Jaguar. Recording computer time was set by Windows network time.
