Could tell us more about your setup. What equipment do you have, i.e.,
sensor, A/D converter, system to convert sensor information that goes to
WinQuake. You may want to get Larry Cochrane's amplifier/filter and A/D
boards. He makes it so simple. You can also get from Larry a Garmin GPS unit
to keep your system time very accurate. It is all automatic. You use WinSDR
to gather and display the data and when you get something interesting to
analyze you save the data and send it to WinQuake. It's a piece of cake.

There Is Only One Way I can Get Winquake to
see right times for my data.

It is necessary to crop the data to the nearest
second before giving it to Winquake.

No matter what I do WQ will not see fractions of seconds
for the start time.

No matter what the precision is of the numbers
WQ only will show the first sample to a whole second.

Like if I tell it 23:49: 20.4 for the first second
it will show only 23:49:20 for the first sample

SO you must run your data until it gets to
23:49:21 then crop it from there to the end
before giving it to wq and tell wq
it is 23:49:21.0 and you can forget the fractions
your start time may be a couple milliseconds off
but WTHeck.

Otherwise if you do not do this things just aint right.

Also, the various filters in the WQ3 FFT used to work fine
but since installing the new WQ3  those filters dont work (all grayed out)
What am I doing wrong ?
