[RFI] Not a GOOD solution to Class D amplifier RFI

[Cortland Richmond <ka5s@earthlink.net>]

--"One solution that seems to have been ignored, up until now, is to set 
the class-D switching frequency above the AM band. It virtually 
eliminates the problem. On that front, Texas Instruments has introduced 
a new class-D amplifier IC that operates at 2.1 MHz. Beyond minimizing 
the EMI issue, the chip also allows for smaller inductors and capacitors 
in the output filter."--
