What's your elevation?

Even in the woods I've found elevation to make a big difference on those. A guy 
I consult has a really bad noise floor in the 5GHz band, pretty sure he has 
another's ptp shot shooting right between three of his towers.

If/when he goes sectorized with 5GHz it will be easier to track down, though we 
could just send someone up there with a NBM5 and have him turn slowly.

  Well, a little more information might be helpful.  You say links, does that 
mean these are PTP links?  Same antenna gain as the other links that have lower 
noise floors?  How big an antenna?  Could this link have more gain, or be 
pointed at a distant noise source?

  What kind of radios?

  Bottom line, there is one way to eliminate a bad radio as the cause, and that 
is to replace it.

  You could also try turning off your other radios briefly during a maintenance 
window to see if they are bleeding into this one.

  Haha. No but it looks like one device that decided to take the whole band and 
add a 10db noise floor. we are used to -90 then a bunch of -60 signals in 20Mhz 
and at most 80Mhz chunks. Just thought if I was missing something

    Where Jon's at there are more trees than people. Shouldn't be a lot of 5 
GHz there.  ;-)

    -80 high noise floor?????

      We have a link with an unusually high noise floor of -80 across the board 
at a very remote location. Other ends of the links and other links at the tower 
are seeing -90 noise floor through the band which is expected. Any idea why we 
would see the higher noise floor on a link end that's across the whole 5Ghz 
band that should be very low?
