Annular Solar Eclipse 2023: recordings of the entire medium-wave AM broadcast band from near Masset, BC, Canada, Part 1

recorded by Nick Hall-Patch, VE7DXR

Grid square of location recorded:  CO44aa 

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 1518UT to 1732UT from near Masset, BC, Canada.   They are part of a set of such recordings made from 13 Oct 1330UT to 15 Oct 1715UT.   Maximum obscuration of the sun was 69% at 1619UT. 

Data files are .wav format, but the archived files are .zip, with about ten .wav files packaged together in each .zip file, using the prefix "VE7DXR-Masset-wideband_125_2125kHz".  As the total files recorded during the solar eclipse exceeded the Zenodo 50GB limit, the remainder of the dataset is found in "Annular Solar Eclipse 2023: recordings of the entire medium-wave AM broadcast band from near Masset, BC, Canada,  Part 2”

The recordings not included here or in Part 2 are available to provide reference data for the eclipse recordings.  Please contact HamSCI at [e-mail] if you require this data. 

Antenna:   North oriented Beverage, 450' length, unterminated; amplified by DX Engineering RPA-1 at receiver.  

Receiver:  SDRplay RSPdx with RF gain = 20dB and using HDR mode, with center frequency 1125kHz, recording 2000kHz wide passband, using SDR Console v 3.2 build 2643.  Although the RSPdx was not frequency locked, a Bodnar Mini Precision GPS Reference Clock outputting 1705.0000kHz was on site, and its accurate signal was recorded in the data.   Computer time accuracy was determined by Windows NTP server.
