When the carrier locks, the program flashes the Amiga power LED to indicate binary frame synchronization! By setting up Paula's audio DMA to double-buffer incoming 8-bit samples, the 68020 has plenty of cycles left for the Costas loop. Source code and executable will be released on Aminet under mus/misc/stardust_amiga.lha next week. -- Sven Weber -- RWTH Aachen Informatik "Hold for relay."
