Yep, there ARE generally solutions.... After several months of 
consternation, I found that a Sears/Craftsman battery-powered drill 
charging station was the culprit.  It pretty much did-in 80 meters while 
anything was on the adjacent work bench being serviced.  No wonder MDS 
values were "somewhat reduced".....hi!!  I still have some noise on one 
80 meter dipole and not on a B&W dipole with similar azimuths? Proximity 
to something out there....
