Effects of the 2024 total solar eclipse upon reception of North American and trans-Atlantic signals in the medium-wave broadcast band, using software defined radio files recorded in Stratford, PEI, Canada.
Bibliographic record
Abstract
Recorded by: Brent Taylor, VY2HF. Grid square of location recorded: FN86 Maximum obscuration of the sun was 99.5% at 1938UT 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 1825 to 2048UT from Stratford, PEI, Canada. They are part of a set of such recordings made on 8 April 2024 from 1659 to 2207UT. The recordings not included here are available by contacting HamSCI at am-eclipse@hamsci.org, if you require this data. Data Quality: Only limitations are a few spurious carriers, a couple of short data dropouts (<20 sec), and ~20 minute long bands of broadband local electrical noise, particularly below 900kHz. 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 “VY2HF-Stratford-wideband_500_1750kHz_". Antenna: ALA1530 loop, orientation 60-240 degrees . Receiver: RSPdx, not locked to a frequency standard, with center frequency of 1125kHz recording a 1250kHz wide passband, using SDR Uno software. Recording computer time was set by BKT Time Sync and tied to a GPS reference.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.
How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
