Yes. (If you can do it by ear, be sure the computer
can also do it....)

You click on it once. Usually it is good enough, but you may
click a few more times - or move the BFO. You want to click
for the power spectrum to match your filter. The bandwidth
may be slightly different for different stations and you may
adjust if there is any reason, then move the BFO accordingly.

The idea is to present the CW in ascii format - but this part is
on qrx as so many other things....
