Effects of the 2024 total solar eclipse upon reception of North American and trans-Atlantic signals in the medium-wave broadcast band, using a Beverage antenna and software defined radio files recorded in Portneuf, QU, Canada.
Bibliographic record
Abstract
Recorded by: Sylvain Naud. Grid square of location recorded: FN46bq Maximum obscuration of the sun was 98.4% at 1930UT 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 1820 to 2043UT from Portneuf, QU, Canada. They are part of a set of such recordings made from 1730 to 2133 UT on 8 April 2024. Data Quality: Only limitations are a number of weak spurious carriers and some short (~15 seconds) data dropouts. 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 “SNaud-wideband_500_1750kHz_ “. The recordings not included here are available by contacting HamSCI at am-eclipse@hamsci.org, if you require this data. Antenna: 400m /1300ft Beverage @ 55 degrees; no termination Receiver: SDRPlay RSP1, with center frequency 1125kHz, recording a 1250kHz wide passband, using SDRUno software. Hardware was not locked to a frequency standard. Recording computer time set by Windows network time.
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.
