I am currently trying to get a BeagleBoneBlack to comply with Class B 
Radiated Emissions levels.
I am seeing noise spikes at various harmonics which I believe are 
originating from the LCD PCLK running at approx. 38MHz.
These are spikes are at 307, 345, 384, 422, 460, 499, 537MHz, etc. and are 
at or above the limit for Class B emissions.
Has anyone else managed to solve this problem and limit the harmonics 
propagating through the system?
Thanks.
