[RFI] Ferrite bead disintegration

Sure, but someone suggested that maybe my recent lightning strike had 
gotten it.  When in use, it was lying on the ground at least 300 feet 
from my transmit antennas and tower.  Also, winter is not lightning 
season here, and my RX antennas aren't deployed during the spring and 
summer.  I'm much more inclined to think some combination of moisture 
and thermal cycling - perhaps even freezing - may have been responsible.
