I think the radio may have to be in TUNED front end mode to enable the =
HPF board, so make sure you test in this mode rather than "FLAT". In =
TUNED mode the sensitivity should drop off below 7.000 mhz as the preamp =
changes there, but the drop off below 3.500 mhz is not normal.

I was just reading the thread on 80M sensitivity. I too experienced =
a drop off in background noise below 3500, but only in tuned front end =
mode (menu 8-4). In flat front end mode, there was no difference!
