have a look at the MSE stats which is kind of a SNR value.. since I run
dual core xpic mode this is very helpful in determining interference.
Hopefully you have a base line of when it was installed to compare notes
because this will certainly let you know if something has changed
drastically

Is there anything he can do to confirm interference or rule it out,

even possible)?
What do the big carriers do in such a case? Can the radios monitor
for signal level if the other end is muted? Sending someone up the
tower with a spectrum analyzer and a waveguide adapter seems not
feasible if this happens for 5 minutes a couple times a day.
Cambium saying it “might be interference” doesn’t seem particularly
helpful unless you can test their theory.

If it is interference then I would be checking with comsearch or one
of the other coordinators to see if anything recent has been issued
for license.
If not then a re-check on alignment would be the other step taken.

Any cambium 820 support people lurking on here? I've been having
trouble with an 18ghz 820C link since the beginning of July and My
support ticket only get's updated by Cambium every couple days. I
was hoping that there might be someone who would be able to help
me out with a little quicker turnaround.
It's modulating way down on 1 chain in 1 direction a couple times
per day, for less than 5 minutes. Most of the time it works fine.
The last work from support was that they think it might be
interference. I'm hoping to get a little more direction in trying
to track down what's going on, but with only a few responses per
week, I'll be working on this until Christmas.
Thanks,
Nate
