I can think of two reasons. First, cable shields are not bonded to the 
chassis at the point of entry; instead, they are capacity-coupled, and I 
suspect that the board itself is not well bonded to the chassis. Second, 
far too many hams fail to do proper bonding in the shack and on the 
operating desk.
