025 We use Baofeng's "heart" for Our Projects (SA818, DRA818)

Picked one by one from a mixed channel. Transcript check: both title readers certain; 5 of 5 sampled certain picks confirmed by transcript, none failed. Channel rule: Include the tutorials, technical explainers, and build or measurement guides (for example NanoVNA, antennas, SDR internals, wireless basics, AREDN, LoRa/APRS, QRM hunting, timing references, and QO-100 parts that explain specific technology such as the PLL or antenna build); exclude video-proposal/promo uploads, product-evaluation videos ('replacement?', 'is it any good') and project-update logs.
