Mal,

when does one ever has 100% certainty ?
I know that in the UBA QSL bureau about 0.3% of all incoming cards are for=
 unexisting ON calls.
That would mean that for an average QSO there is a 99.7% chance that the=
 call is copied correct.
In that view 99.9% certainty is not bad at all and probably better that fo=
r the averaga QSO on HF.
Of course you can doubth any QSO, but in that case it might be better to=
 go fishing ...

Andy
But not 100%. You have left 0.1% to the imaginatiion and that gets stretch=
ed
at times.  There must be no doubt, no guesswork or brushing,  only absolut=
e
proof.
You must have seen the senario here lots of times ie I saw a squiggle!! Th=
e
freq seems right so does the time !! I got a 3 mm screen shot over a perio=
d
of 24 hours must be you!!
To avoid spurious reporting there must be positive ID SENT, one symbol or=
 a
cut in long carriers at intervals.

If the timetable shows the bus leaves at 1258, and it does leave at 1258

And it arrives at 1445. when the timetable says is should.

Then stops

And the the bus drives along a road of 430uHz
And it at least 4dB above the road surface in that width.
And you look just for the presence of the bus (rather than its shape
and direction)

Then there is a 99.9% certainty the bus was there

That's basic information theory.   Not gut reaction, perception or
intuition or belief or fantasy
Just basic maths.
