Is there anything he can do to confirm interference or rule it out, short of coordinating a different set of frequencies (assuming that is 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 not then a re-check on alignment would be the other step taken. On 8/13/19 12:43 PM, Nate Burke wrote: 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
