I'm not sure, but I think the BW of a 30 wpm CW signal such as you will 
hear in contests exceeds 50 Hz.  The code elements pretty much run 
together at that BW for me, and I really can't discern much.

And you're right, my autospot doesn't work unless the CWT bar is 
moderately stable, regardless of NR settings.

I was struck by the fact that I can even set my radio for 50 Hz BW!  I 
wonder what the BW was on my Drake 2B with the Q-mult set just below 
oscillation?  Things sure have changed.
