- R1 locks 315 MHz with narrow FM deviation + LFSR; R2 locks 433.92 with max deviation - Remove VCO sweep tables, tickSweepFast, and hop loop; ~2.4KB RAM saved - Telemetry jam_fixed + graph centers on lock freqs; UI/OLED/README updated - Apply Sweep only persists NVS; power changes re-apply lock freqs/deviations Made-with: Cursor
