Oh yes! I have done some tests with TF3HZ's grabber and I can see my 
Op32 on a QRSS screen when he was decoding at very low levels. 
However, there is not much in it and Opera is very impressive in 
resolving weak signals. 

For beacon and propagation tests Opera reports are so much more 
convenient than taking snapshots of images of a QRSS grabber screen. 
For a QSO, QRSS/DFCW may well be more useful, but the path conditions 
can be more easily determined using Opera. It is "horses for 
courses".
