[TenTec] OT: RFI from Plasma TV?

[Bob McGraw - K4TAX]

Keep in mind that all TV's sold are required to meet strict conditions of 
both radiated and conducted types of emissions.  I've previously been 
involved with this type of testing and know sometimes it's tough to make the 
numbers.  Should the manufacturer "fake" the numbers then they place 
themselves at great risk both financially and likely having to pull the 
products and modify same to be in compliance.  Unfortunately it is up to the 
complainant to prove the design and manufacturer is at fault.  Other than 
taking the offending TV to a certified testing lab, it is difficult for an 
individual to conclude that a non-compliance condition exists.

The fact that you purchase a TV and experience noise or birdies when it is 
on, this is by no means adequate to conclude that the TV is in 
non-compliance.  Just expect to take additional measures to clean up your 
QTH.  As to the neighbors TV's...........good luck!

As to their ability to reject interference, there is little protection for 
the consumer in this area.
