What happens if a signal that is 140 dB above the noise floor comes along, a
condition quite common in Europe?
Have you tested for this condition?

PS: I think that the rather nice Flex 6500 does have pretty good bandpass
filtering before the A to D to help its performance in regards to strong
out-of-band signals. I think that is where the 7300 comes up short and is why
Icom recommends a preselector.
