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 Muskegon, MI, USA, fed by a southeast DKaz antenna
收藏资源简介：
Recorded by: Tim Tromp, KE8JFM Grid square of location recorded: EN63we Maximum obscuration of the sun was 91.7% at 1911UT 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 1755 to 2035UT from Muskegon, MI, USA. They are part of a set of such recordings made from 1754UT on 7 April, 2024 to 2215UT on 9 April, 2024. Data Quality: Generally good, but there are a couple of short (<15 seconds) data dropouts. Data files are .wav format, but the archived files are .zip, with about four .wav files packaged together in each .zip file, using the prefix “KE8JFM-wideband_305_1905kHz_“. The recordings not included here are available by contacting HamSCI at am-eclipse@hamsci.org, if you require this data. Antenna: Southeast DKAZ (140° ) 140 FT long x 22 FT tall, Wellbrook FLG100LN-093 amplifier, 846 ohm (Fixed) termination (background details in enclosed "AntennaDetails-DKaz.pdf") Receiver: Perseus, using 10dB front end attenuation, with center frequency 1055kHz, recording a 1600kHz wide passband, using Jaguar Pro version 9 (2023-12-31) software. Hardware was not locked to a frequency standard; a Bodnar Mini Precision GPS Reference Clock outputting 1705kHz was used as reference for Jaguar. Recording computer time was set by Dimension 4 and updates every 5 minutes (time and date in recordings used UTC).
