收藏资源简介：
Recorded by: Mike Boice, KW1ND Grid square of location recorded: EM75wx Maximum obscuration of the sun was 88.7% at 1908UT 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 1745 to 2027UT from Knoxville, TN, USA. They are part of a set of such recordings made from 1000UT on 7 April, 2024 to 0100UT on 9 April, 2024. Data Quality: Generally good, but there are some spurious carriers, and short data dropouts (< 20 sec), 3 or 4 per hour 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 “KW1ND-wideband_500_1750kHz_“. The recordings not included here are available by contacting HamSCI at am-eclipse@hamsci.org, if you require this data. Antenna: 160ft LoG (Loop on Ground; approximately 40ft per side) Receiver: SDRplay RSPdx, RF gain 35.7dB , with center frequency 1125kHz, recording a 1250kHz wide passband, using SDRUno v. 1.42 1014 software. Hardware was not locked to a frequency standard Recording computer time was set by Meinberg NTP on active internet connection (time and date in recordings used UTC) .
