Re: [AFMUG] 820 Support Help
40 or 80 MHz channel? MC-ABC or external LAG? If it's 80 MHz, I assume external LAG since Cambium doesn't have SFP+ until the PTP850C comes out, and the combined capacity would exceed 1 Gbps. How are you measuring packet loss separately for each polarization? And you're sure it's at the RF level? Not the Ethernet (of optical) interface? MSE going from -38 to -34 doesn't sound like a dire situation that should affect error free operation. Maybe lose some capacity, but not drop packets. I guess a question I would have for Cambium would be why does this cause packet loss rather than triggering ACM? They can speculate that it's interference, but if it's only bad enough to drop the MSE to -34, why does the radio not handle that without packet loss? Granted, as a conventional licensed microwave radio, the PTP820 doesn't use ARQ (which would introduce latency), but mechanisms like ACM and adaptive xmt power and ATPC should work smoothly and yield nearly error free operation. Maybe if there's a burst of interference a few packets get clobbered while ACM kicks in, but you are seeing minutes of degraded performance. I think the quick config scripts set ACM thresholds for when modulation should change. I've never fiddled with these, but maybe that would help?

Nate, That almost seems like a little more alignment may be needed.
What does your link planner file say for recommended RX levels and it
should show some other expected values as well?

Re: [AFMUG] 820 Support Help
One thing to look at that often gives you a hint as to the cause is the the signal strength during the period of interest. An interferer rarely causes the signal level to drop. Instead the noise (and sometimes the signal) level rises to the point where the radio cannot maintain a link. I've also seen where too strong of a signal can cause this issue. The signal gets strong enough that the receiver saturates and the radio cannot maintain a reliable link. A brief dropoff would indicate something in the path.I.E. delivery truck fade.
