Annular Solar Eclipse 2023: recordings of the entire medium-wave AM broadcast band from Lockhart, TX, USA, Part 2

Files recorded by Mark Whittington, AG5RT

Grid square of location recorded:  EL19ET 

Maximum obscuration of the sun was 89% at 1654UT.  

These data files are recordings of the entire medium wave broadcast band (535-1705kHz) made during the annular solar eclipse of 14 October 2024 from 1524-1833UT from near Austin, TX, USA.  They are part of a set of such recordings made from 13 Oct 2135UT to 14 Oct 2138UT. 

Data Quality:   many spurious carriers, most very weak, so may not affect overall quality

Data files are .wav format, but the archived files are .zip, with two .wav files packaged together in each .zip file, using the prefix "AG5RT-wideband_15_2015kHz”. As the total files recorded during the solar eclipse exceeded the Zenodo 50GB limit, these files are the remainder of the data files found in "Annular Solar Eclipse 2023: recordings of the entire medium-wave AM broadcast band from Lockhart, TX, USA, Part 1”.    Please see that record for software and for supporting documentation.

The recordings not included here or in Part 1 are available to provide reference data for the eclipse recordings.  Please contact HamSCI at [e-mail] if you require this data. 

Antenna:  40' vertical

Receiver:   RSPduo, with SDRuno software, using center frequency 1015kHz, recording a 2000kHz wide passband..     "IF AGC" was unchecked; IF gain was set at 0 dB.   The RF gain control was set one click below where the OVERLOAD indicator would flicker.   The receiver was not locked to a frequency standard.  Computer time accuracy was determined by Meinberg NTP.
