Dear Alberto,
Also the problems of occasional double letters, and systematic
errors are under scrutiny.
I have noticed that when the transmission stops and Jason is exposed
to noise, he (it?) usually repeats the last transmitted character.
Judging from the waterfall, Dave transmitted only a single K at the end of
his transmission but I got five K's on the screen! Statistically, that shouldn't
have happened unless Jason has some kind of unintentional "memory"...?
Even when receiving noise only, there are often sequences of 2 to 5 equal
characters.
Maybe LF noise isn't random chaos after all... :-)
