Interesting question. Is it literally "impossible" for the brain to decode PSK or FSK or is it just really difficult? Are there discernible patterns in the tone sequences used or are they too complex to learn to discern, even if sent very slowly? Not important at all, just curious! -- Thanks! & 73, doc, KD4E ... enjoying a sunny CHRISTmas in Florida :-) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Thank our brave soldiers this season: http://www.letssaythanks.com/Home1024.html ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ URL: bibleseven (dot) com
