Smittix	c0c066904c	Fix Morse decoder scope events not reaching frontend ... Replace blocking rtl_stdout.read() with select()+os.read() so the decoder thread emits diagnostic heartbeat scope events when rtl_fm produces no PCM data (common in direct sampling mode). Add waiting-state rendering in the scope canvas and hide the generic placeholder/status bar for morse mode. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-02-26 09:30:58 +00:00
Smittix	2eea28da05	Fix Morse decoder silent on real HF signals via AGC and warm-up ... Add automatic gain control (AGC) before Goertzel processing to normalize quiet audio from direct sampling mode where the -g gain flag has no effect. Fix broken adaptive threshold bootstrap by adding a 50-block warm-up phase that collects magnitude statistics before seeding noise floor and signal peak. Lower threshold ratio from 50% to 30% for better weak-CW sensitivity. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-02-26 09:10:37 +00:00
