<pre wrap=""><i>I have carefully followed the path and believe that bufl was the "left"

that left is the I (in phase or real) sample and right is the Q

I am not familiar with PowerSDR, but if they coded it according to
FlexRadio specs, it has<br>
I and Q reversed with respect to the de-facto standard, i.e. I on
left channel and Q on right.<br>
<br>
Flex decided that "I" should be on the Right channel, and "Q" on the
left, for reasons not known to me....<br>
In my software, when I read a recorded file coming from Flex (easily
recognized, and they <br>
save the I/Q data as 32-bit floats, and they are the only ones to do
this...) I automatically<br>
activate the I/Q channel swap...<br>
