The meaning of a single point star grounding system is badly 
misunderstood. Likewise, the difference between grounding and bonding is 
badly misunderstood. A connection to earth is NOT part of a solution to 
RFI/EMC issues. Proper BONDING IS. And the method I've shown in the 
tutorial IS best for EMC and for lightning. Remember -- EMC goes from DC 
To daylight! About ten years ago, I consulted to a mic manufacturer 
about RFI from cell phones to audio systems in meeting rooms of the US 
House of Representatives. The primary coupling mechanism was a Pin One 
Problem in the FET follower line driver for the electret mics. The cell 
phones were running 1W or less, pulse modulated, in the ranges of 900 
MHz and above.
