HL2 band survey, 2026-11-04

Recordings, not firmware. The Hermes-Lite 2 (gateware 74.2, N2ADR filters, a 40 m end-fed half-wave) recorded on a computer with tools/hl2_record.py, one band at a time, 30 minutes each on 10, 12, 15, 17, 20, 30, 40, 60, 80 and 160 m: one tar per band holding its 48 kHz 24-bit I/Q WAVs (one per 15 s slot, Q as the radio sends it, negated by the scorer) and manifest.jsonl, plus the run's log.

How it was run and scored, the results, and each file's SHA-256: tools/decode_bench/corpus/hl2-2026-11-04/README.md in the repository.

QMX IQ vs audio on the P4, 2026-11-03

Logs, not firmware. The P4 decoding a QMX (firmware 1_04_010) from its IQ mode against its demodulated audio, alternating every two slots, on 20, 15, 17, 30 and 40 m on 2026-11-03 (row y9bt, stage 3), plus that morning's sequential runs.

How it was run and scored, the results and what each file holds: tools/decode_bench/corpus/qmx-2026-11-03-device/README.md in the repository.

QMX IQ vs audio corpus, 2026-11-02

Recordings, not firmware. A QMX (firmware 1_04_010) recorded in IQ mode and in its normal audio mode, two 15 s slots of each in turn, 30 minutes on each of 15, 20 and 40 m on 2026-11-02, for row y9bt's stage 2.

Each tar holds one band's 120 WAVs (48 kHz stereo 24-bit, named for their UTC slot) and its manifest.jsonl. How they were recorded, how they were scored, the results and every SHA-256: tools/decode_bench/corpus/qmx-2026-11-02/README.md in the repository.

The recordings are of public amateur-radio FT8 transmissions.
