I have received some email from people that don't know where to find 
my Technical Tidbit this month as I forgot to mention it in the 
original email. The article is linked from the picture of the 
experimental setup at the bottom of the index page of 
http://emcesd.com which shows a cable, scope, and plastic bag with coins.

Abstract: ESD events between small pieces of metal, such as coins, at 
low voltages produce intense EMI with bandwidths into the tens of 
gigahertz. The problem is much worse when an electronic device, such 
as a mobile phone, is immersed in the coins as often happens.  Data is 
presented to show possible voltages induced into a mobile phone 
antenna by nearby small metal ESD events. RF front end damage to the 
receiver is a distinct possibility. (even though there is no direct 
contact with the ESD events)
