DeepSeek V4.1 Flash’s P25 review, graded
Right about the chip, wrong about the CPU. It finds the microphone route and a fatal de-emphasis setting UNIONALPHA missed, then clears a vocoder that needs 11–16× the radio’s CPU.
The audits, in full
Each audit is a long-form report: every claim checked at the lines it cites, the model’s evidence rerun, and what it missed modelled through the firmware itself. They are published here as written, newest first.

P25 voice decoding on the DM-1701
The brief“Find why this firmware struggles to decode P25 Phase 1 and Phase 2 voice on the radio’s HR-C6000, and what to do about it.”
UNIONALPHA’s P25 review, graded
Accurate to the line number, silent on what stops the radio decoding: an audio high-pass that leaves zero decodable voice frames, and a vocoder that needs 11–16× the CPU.
