All I know about others' experience is that I have heard there were problems on this forum. But this is extremely easy to check out. I used to teach EMI testing seminars. In order to minimize test equipment needs, I would use a small TV receiver as an EUT, and feed it a signal on channel 3 or 4 from a VCR. I used a bulk current injection clamp to drive currents onto the interconnect coax. All it takes is an rf signal generator, especially if you use an in-line attenuator out of the VCR to reduce the TV's incoming signal to an MDS type level. Anyway, I would show that cw didn't affect much, but AM tore up reception. I also mapped the IF filter pass band by sweeping the signals source and recording the TOS level (threshold of susceptibility). You could do exactly the same, but investigating the effects of FM rather than AM.
