There's a trip down memory lane ...

For those that may have not been around for the 'fun' see http://w3eee.com/ and click on KFI. This 
went on for quite a while with reception reported from around the globe. One night I set up a 6" 
ferrite rod (tuned) on the back deck just to see if KFI could be received on such a small antenna. 
The special KFI 'signature' was solid copy when checking the captures the following morning.
