I may have hit pay dirt, of a kind, this past weekend at a hamfest.  I 
bought two new Filter Concepts 60v, 100A DC EMI filters for $20.  
According to their spec sheet, looks like 60db attenuation for either LL 
or LG, out to 20 MHz. According to the website, they were designed to be 
used with switching power supplies.  Heh.... maybe these 20A Chinese 
"LED Strip" 28v power supplies can be tamed, at least below 20 MHz. The 
filter weighs three times what the power supply does, but, what the 
heck.  A Corcom on the a.c. input should about do it...?
