Can you tell me the "class of device" and exactly what Part of the 
FCC Rules the mfr told you covers it?  The so-called "electronic 
transformers" (actually switching power supplies) that run 
architectural low voltage (12V) lighting have taken over the track 
lighting world. I inherited several in the home I bought when I 
moved to CA three years ago, and they are VERY noisy. Go to an 
electrical supply store to buy a transformer, and that's all they 
have. Not only that, but the lighting fixtures are built in such a 
way that a REAL transformer won't fit, and won't fit in an 
electrical backbox that fits in the ceiling or wall. 

This is a VERY big issue looming on the horizon (bigger than BPL by 
a lot), and the ARRL seems to be asleep at the switch. When a 
neighbor installs one of these devices, your enjoyment of ham radio 
is going go downhill fast.
