Topband: Patience in ARRL 160 Contest -- copying weak ones

[Doug Renwick]

George, IMO you have solved the problem ... mental.  Your last sentence
describes the condition exactly ... your brain goes blank or slows as a
defence mechanism from all the noise/signals on the band.

After spending 12 nights-in-a-row straining to hear and 
assemble thousands of weak calls, I would cautiously agree 
with Herb: if the DX clearly has the prefix, just send the 
missing letters.

Maybe it is mental, maybe something else, but time and 
again I heard clearly (almost loud) the caller's prefix 
and number, just to experience the rest kind of fizzle 
into something weak and incoherent ... This happened so 
many times that I was ready for it, focusing only on the 
suffix, and still many times I could not copy it, while 
the prefix came through (almost) loud and clear. It must 
be that you can "hear" what you know or expect, while it 
is much harder to hear and decode something random. But 
that does not explain the whole thing. How does one get 
the prefix so many times correctly when the suffix just 
fizzles into nothing. I have checked with the other 
operators on PT0S and they had similar experiences.

Perhaps there is some hearing mechanism at work, similar 
to vision; where acuity diminishes with usage...

73,

George
