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. Source code and executable will be released on Aminet under mus/misc/stardust_amiga.lha next week. -- === Hugo Kim === Dept of Electrical Engineering, NETCOM On-Line Communication Services "We don't sign stars.
