[RFI] Getting a Gas Furnace, and Electric AC unit...

Jim and All,

I strongly suspect (but can't prove) that one reason (maybe the MAIN reason) that engineers at the appliance makers are so lacking in EMC/RFI knowledge is the "free pass" they get from the FCC on meeting emissions standards.  I just attended the 2012 IEEE EMC Symposium in Pittsburgh, and I can truthfully say that I do not recall seeing a single attendee there from a major appliance company.  The same holds for the past many years, as well.  Of course, some appliance makers have other divisions that might have attendees in the EMC areana, but I have to wonder.

Except for active hams, doing something about emissions from one's own equipment is just not a priority item, at least for US-based makers.  I know we have some subscribers in Europe and Canada, so if yhou happen to know if your country's regulatory body applies RFI standards to major home appliances (clothes washers, dryers, dish washers, etc.), please post comments.  Thank you.

73, Dale
