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"...?

Maybe LF noise isn't random chaos after all... :-)

Dear Johan,
  yes, that's what I have observed too. I would like to beleive in your last
sentence, thinking that in the chaos there are some 'strange attractors'  :-)
but more realistically I think to have found in the decoding logic what could
explain that. During this coming weekend I will change the signalling format
to use the 17-slot method, and will do also some tests for the above.
Thanks for the report.
