This raises another question (hence the change in subject).  Ever since 
I can remember, I have been more able to coexist close to another 
station if it is down off the low-side response of both my 400 Hz filter 
and the sideband filtering of the radio - that is, with a beat note of 
<300 Hz or so.  Conversely, I have much more trouble coexisting with a 
nearby station that is above me in beat note.

Do others routinely switch from USB to LSB CW?  One thing that deters me 
from doing this is that with my radio, at least, I have to retune 
substantially to get back to the frequency I was on.  It occurs to me 
that it might be a useful function for contest logging software to 
automate this process - switch sidebands and offset the tuning by the 
relevant amount.
