I am using a 17" KDS Avitron CRT with all Trinitron (Sony) guts that is 4 feet from the radio.No RFI whatsoever. I also have an older Sony SVGA about 6" from the radio and antenna tuner that is running off a laptop and it is quiet as well. I have had some problems with a neighbor's flat panel TFT, but it was not certified for home use. He sold it. W6EZ
