[TenTec] Scads of used Icom IC-7300

[Gary J FollettDukes HiFi]

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?

Regards and 73,

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.
