[SixClub] Re: CW vs PSK = Brain vs Machine Decode

[Gabriel Sierra]

Hi, 

a code is a code. I once saw a HAM in a hamfest who
could decode RTTY just by hearing it, hard to believe,
but me and a couple of ham friends saw it. I can not
do it for sure! The point was that an assertion was
made that PSK and other digital modes were not real
radio. If you send them by radio, it is radio! That is
my point! A brain does not make radio waves, a radio
does!
