Todd,

> I  couldn't see anything on QRSS either looking at your frequency.

Given the  short duration of the frequency steps, you probably would have 
to look at a  QRSS3-type screen. I don't think you'd see anything useful 
on a 30 second  screen. And yes, don't expect QRSS30 weak signal 
response. The mode doesn't  appear to fare as well as you might hope with 
static crashes, AC-related  buzz and nearby steady carriers. Hmmm...can 
you spell "LF"?

Hi John,
You are right, it is  not very useful to try to  look at WSPR on a QRSS 
screen
at much over QRSS3 from what I remember over  the winter. At QRSS10
and longer the freq shifting carrier seems to get lost  in the time buildup
on the screen. It probably tends to be neglected more as  random noise at 
the much
slower speeds.

Also WSPR does seem to be a  bit more subject to degradation from static 
crashes,
line noise,  buzz  and nearby carriers.  It does do well on MF/HF on a 
fairly 
clear  frequency free of static and nearby QRM. Its great advantage is  to 
just  let it 
run continuously for automatic printed decodes at the receiver end  and it 
is
fairly narrow band compared to other modes.
