I live in the city of Chicago, and have lots of broadband noise. That noise 
generates lots of ringing in sharp filters, but all the ringing I hear is 
excited by that noise hitting those steep filter slopes -- stuff like computer 
hash, power line noise, and plain ordinary QRN (static generated by 
lightning). 

I don't find that SIGNALS cause enough ringing to be a problem. Of 
course, I don't work above 30 wpm nowadays. :)
