Thanks Dave. Your input as an EMC pro are greatly appreciated.

The reason I ask is that, historically, nearly all of the emphasis on 
EMC from mfrs seems to at VHF and above. It's encouraging to see that 
some are now looking lower in frequency. Almost 15 years ago, Warren 
Shulz, CE at WLS (50kW on 890 kHz about 25 miles SW of Chicago) told me 
that Fords were so noisy that their radios couldn't copy his station in 
northern suburbs 50 miles away!
