I've seen the video and I can easily replicate that by listening to a powerhouse broadcaster, tuning off frequency, and walking into a wideband multipath / phase distortion field.
The station's studio location could be far away, yet the remote transmit site could be next door. There could be mixing products and all sorts of things we just don't know about.
It could be that the RX7 is wider than normal for wideband FM, but the most important thing to me is that it doesn't bleed into the other bands! At least not with the supplied antenna.
Hard to say if he has a bad unit or not. For me, broadcast reception is a secondary, if little-used feature. I must say the Icom has superb mono fidelity when using good headsets.
