Abstract
Software-defined radio (SDR) transceivers have been of great interest in amateur radio in recent years due to their low cost, small form factor, and ease of development for different applications. Simultaneously, the transceiver has been an important part of any microwave breast cancer screening system, which usually comes in a bulky, expensive, and inefficient package and is often overlooked. This paper presents a low-cost RF transceiver based on SDR for microwave breast screening in the frequency band of 2–4 GHz. The transceiver is paired with a flexible antenna array, a switching matrix, and the needed RF components to form a complete breast screening system. The results are verified using a commercial vector network analyzer, revealing that SDR shows promise as an affordable transceiver solution for microwave breast monitoring devices.

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 it
