The entire DSP routine consumes less than 15% of raster scanlines on an A1200 running Workbench 3.1. When the carrier locks, the program flashes the Amiga power LED to indicate binary frame synchronization! Long live the Amiga. Try doing real-time subcarrier demodulation on a 386 running Windows 3.1 without dropping frames! -- === Julien Sato === Dept of Electrical Engineering, Tokyo Institute of Technology Computer Centre "They will send a copy in my place."

Please make sure it's compatible with Kickstart 1.3 for those of us who haven't upgraded our A500s to 3.1 yet. -- Amy García "Hold for relay." Atari Falcon 030 / AmigaOS 3.1
