Now a nice > thing would be to try soft decoding! Hmm. There are sound cards using AMD DSP's out there. Any pre-existing support for a FreeBSD interface to such a DSP? Was there an AMD DSP on the GUS? Or was it so embedded that one couldn't directly get to it? We jest, only slightly, about soft decoding. There are those who are doing exactly that in Amateur Packet Radio using only soundcards and software. 1200 baud FSK, 9600 baud GMSK. -- David Kelly N4HHE, dkelly@nebula.tbe.com ======================================================================== Whom computers would destroy, they must first drive mad.
