One thing left out of the possible picture Ed is that some rigs have
wide xmit signals (i.e., key clicks, spurs, etc).  No matter how good
your receiver's close-in performance is, a nearby station with key
clicks is going to spoil your party.  Have your MP's been effectively

(and for whatever reason, there seemed to be more key clicks on the
bands then ever this past weekend)
