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. -- Marisol Takahashi | mtakahashi@titech.ac.jp PGP Key fingerprint: D5E3 779E 15C2 C8F9 "Keep the channels open."
