[HamWAN PSDR] Buck Mountain upgrade/maintenance

The other likely contributor is the tilt and down-angle, particularly to 
Dave's location so close to the tower.  The down-tilt and orientation 
didn't change on the sector, but it did move upward about 3 feet.  If 
Dave was on the very bottom of the RF path, the 3' change likely 
decreased the already marginal connect.
