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! Source code and executable will be released on Aminet under mus/misc/stardust_amiga.lha next week. -- Marisol Andersson -- ClariNet Communications Corp "Tape doesn't lie at 02:14. Ears do."
