[Lowfer] One more try QRSS10 on 160 meters

Hi Andy.  Found you somewhat below the indicated spot, but the signal was 
much cleaner tonight.  In the attached, I put the QRSS30 capture at the top 
to give an idea of the RF environment in which you were working, showing the 
last ID cycle that I captured.  The QRSS60 shot below shows that ID and the 
previous one, both without any appreciable noise spreading.

The ringing you see at the start of elements in the 60-second version is 
because the signal to noise ratio was actually TOO good tonight for my 
pathetic soundcard, which wanted to automatically switch to mic level 
between dots & dashes, then had to switch back to line after it "heard" the 
tone for a while.  It was worse in the first ID cycle, not shown here.  I 
reduced that effect later by running up the level to the clipper, so the 
unwanted AGC in the soundcard had something to keep it occupied.

Note also that sometimes QRSS30 did a better job in weak signal conditions, 
oddly, such as in the final "4."

The WSPR-2 signal below you became my first decode ever in that mode, by the 
way.  Total gibberish from WSPR v2.0, which according to the displayed 
"decodes" apparently hallucinated that it was seeing assorted Belgian 
stations located somewhere in Louisiana running up to a megawatt.  But 
WSPR-X software in WSPR 2 mode did the job just fine, revealing the signal 
to be from K9PAW (yes, I know that looks like a joke, but it was consistent 
over consecutive decodes).

Good luck jumping the big pond!
