JRC Radar Scanner when rotating
There is a seal on the antenna scanner shaft, just below the seal there are two bearings, thou the antenna are enclossed moisture still get inside and get to these bearings. Try and get a small amount of wd40 on the bearings, if not, you will soon begin to see false echoes on the screen because the motor on the scanner or antenna will begin to work harder causing a drag causing these echoes. Good luck.
