I have a Rocket 5AC Prism v8.5.1-cs.37185 (XC) and it's haivng issue with interference. It's on a mast which we have mutiple AirMax radios.
yesterday there was a compaint about network been slow so I've changed to channel from 5735 to 5635 which deemed to be best choise by air magic tool. everything worked great after that.
this morning, channel 5635 had high level of noise as well, so moved back to 5735,
few hours later I see this.
it seems that the noise is folliwng this radio. all our radios are not nearly this channel and the confusting part is that it would be noise free for few hours and then come back to whatever I set the Raket 5AC to

This is something that is very difficult to get around.
If you were having trouble on 5735, go back to 5635 and ignore the noise that you see. Are the stations still having throughput issues?

is it recommended to go to the end of the spectural like 5200, or using 10Mhz width (even it may not as fast as 20Mhz but hopeuflly it would advoid inteference issue better)?

Some frequencies allow higher and lower EIRP values depending on your local regulations, so one channel may reduce your output power, you should see an alert on the dashboard when that happens.
The lower the channel width, the better off you are as far as interference goes. It's always best to pick the lowest possible channel width. This all depends on how much bandwidth you need.

thanks for the quick reply.
we are now back to where we were yesterday, well, worse: Noise level -39dBm at 5635
actuall through put is TX 35-60 Mbps and Rx 1Mbps on local radio
here is the station list. should I reduce the Tx of nearby stations?

Hey, im having the same issue and it does cause perfomance issues.
When it make its own interfence, clients response times go from 15 ms to 400 ms, also cause download and upload rate to go down. I've just changed freq on all the RAC Prism gen2 so I dont have any images of the "dark side of the moon".
I was reading some UAP were making some "scratching noises" and you made all the people with UAP's with scratching noises to fill an RMA.
I would like you to know that ALMOST ALL of my Rocket AC prism Gen 2 are making "scratching noises" and those that are making scratching noises are the ones that go crazy on self made interference.
Also I had to disable DFS in the background because it kept changing freq because of the self made interfence.

Seeing the same issue. Two LiteBeam LBE-5AC-23 units at 7 miles. Change the frequency, looks good for a few minutes. Then it returns. Performance is horrible. This just started happening this week. 40MHz AirMax channels.
Interestingly... we have another pair nearby, same distance roughly. Doing great and they are running 80MHz non-Airmax.
Before this problem started, we had a stable link. Now it is almost unusable.

@UBNT-SNKthe sound is like something is scratching from the inside. The RMA thing is about a post on unifi products (that made this scratching noises).
The thing is that the radio makes his own noise, if you change the freq and let it there for about 1 minute, the freq that you were before goes clean and you can go back to your freq. But later on the freq will go dark red again and you have to keep doing this thing over and over.
Also it affects the overall performace (around 80% loss in performance)download, upload and latency.
(edit) I've also changed for another new rocket and it kept doing the samething.
