Re. : [Meteor-Scatter] Using WSJT/FSK441, advice please

[DEHAYS Dominique]

Then I analysed the captured .wav files from the first successful qsos,
pings were generally 10dB plus above noise, and duration several hundreds 
of
milliseconds; so why was I not decoding properly pings approximately in 
the
range, say  2-8dB and 20-100mS long, even though, as I have already said,
program settings, W, S, DF, Tol, etc suggested I should be able to ?
Somewhere in my setup there must be a lack of sensitivity. Pings either
strong or long decoding OK; but pings either weak or short not doing so

I have exactly the same problem , and I'm still trying to solve it...yet , 
no success
