Опознание БЕЗ разбора рации, по схеме RT4DDLT01 (Radtel v2.1): DMR-модуль «FM100B» = один чип U700 HF6853 — одночиповый DMR-SoC семейства Auctus A6 (внутри RDA8809): CPU + ВЧ-трансивер + DSP + AMBE-вокодер + аудио-кодек в одном кристалле, прошивка во внешнем SPI-flash, кварц 26 МГц. Прежняя версия «Sicomm SCT3258TD» неверна (SCT3258 — baseband-only без ВЧ; и нативный протокол другой). Скрытый ATE/CPS-интерфейс полностью реверснут (jhart99/a6tools, вендорен в research/a6tools). Даёт КОНКРЕТНУЮ починку нашей TX-проблемы: AT+GETFREQERR / AT+DMOFREQERR=N, offset=-2500+10*N, ±2500 Гц — наши ~1100 Гц внутри диапазона. Плюс DMR_ADJTXSYMDEV (девиация), FGU_AFC, DMOSETPOWER, CPS chanInfo, дамп прошивки модуля. - docs/hf6853-auctus-a6.md — идентификация + протокол + план TX-fix - tools/a6_freqfix.py — заготовка тула (probe/read/write, не запускать вслепую) - research/a6tools/ — вендоренный реверс (MIT), atcommands.md/cpecommands.md - docs/dmr-tx-recovery.md, README — путь 0 (AT+DMOFREQERR) как лучший - research/rt4ddlt01-dmr-module-sheet.png — рендер листа схемы DMR-модуля Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NikMGoqQWWk9wy2ww2vJAr
