Looks like the noise floor is fried.

Do you have any other equipment you can verify this with?

Could be a bad CPE or R52HN.

will try with other card to see if samething happens...
that r52hn is new...

I had an R5HN fry after it had been tested on the ground for a week or two. Turns out there was a tiny bit of the outside aluminum insulator touching the center conductor on the LMR400 I used on the tower.

I now test the entire AP as an assembly.
