In DX pileups and contest conditions, this all but makes the radio operate in the same class as my IC706. In other words, unusable.
RF gain set to minimum, filters to sharp. Am I missing some kind of setting?
Running the latest SW with my Maestro.
This is symptomatic of a known WNB problem where it cannot deal with high level close-in signals. Try turning off the WNB and see if the behaviour changes.

FRS have been made aware, but so far no fix.

I beg to differ. Saying “works fine for me” does not mean it should not be looked at again. Being dismissive to other people’s observations and locale is hardly a scientific approach.
The problem appears to be much worse in certain regions where strong BC stations are located just outside of our LF bands, in particular 7MHz and 3.8MHz here in Europe. Take 3.8MHz where I did lots of tests last winter. Here in the winter we see exceptionally strong BC stations above the DX segment, often around 3.85-3.95MHz and can often experience 60-70dB over S9. I can’t speak for the rest of Europe, or the Middle east who are likely to be equally badly affected, but it certainly is a real problem here.
Even with WNB=3 and AGC-T=30 and preamp off, the pumping persists at times. The only apparent cure is to turn WNB off, and rendering WNB a useless in large parts of the world. Taking AGC-T any lower means the implied benefit from WNB is lost because you can no longer hear the DX you wanted anyway.

I would hope that someone is taking it more seriously.
