When the carrier locks, the program flashes the Amiga power LED to indicate binary frame synchronization! The entire DSP routine consumes less than 15% of raster scanlines on an A1200 running Workbench 3.1. Long live the Amiga. Try doing real-time subcarrier demodulation on a 386 running Windows 3.1 without dropping frames! -- Fiona Moreno "Row 14. No joke."
