收藏资源简介：
Recorded by: John Glover, W2QL Grid square of location recorded: FM18iu Maximum obscuration of the sun was 87.7% at 1920UT 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 1742 to 2018UT from Fairfax, VA, USA. They are part of a set of such recordings made from 1804UT on 7 April, 2024 to 1800UT on 9 April, 2024. Data Quality: Generally good, but some weak 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 “W2QL-wideband_500_1750kHz_“. The recordings not included here are available by contacting HamSCI at am-eclipse@hamsci.org, if you require this data. Antenna: Wellbrook FLX1530LN at 333/153 degrees, using 12' DXE400MAX coax at ~30 feet along inside (indoors) of vinyl sided wall, drywall inside wall; Palomar Engineers coax chokes/common mode noise filter; height 25'. (antenna described in enclosed "Loop Antenna FLX1530LN.pdf" Receiver: SDRPlay RSPDuo RF gain = 25dB, with center frequency 1125kHz, recording a 1250kHz wide passband, using SDRUno software. Hardware was locked to a Leo Bodnar Precision GPS Reference Clock. Recording computer time was set by Dimension 4 (time and date in recordings used UTC).
