Hi Phil,
Thank you. We thought of it but would have to change antennas to do that. These can’t go lower than 5485 MHz. L We were hoping to avoid swaping out antennas if at all possible. I’m sure you understand.

Haven't seen anything like that, but the closest weather radar to our location is 50 miles away. With that kind of signal you could try 5200GHz and get away from the noisy 57/5800 band.

It has been running beautifully for the last few months. A few days ago we started experiencing interference spikes that completely disrupts this backhaul. These spikes are apparently random - we could have two in a row within a few minutes and then nothing for an hour or two and again I'm attaching 2 screenshots that show RF Performance at both ends of the backhaul. We are using 5740 MHz with a 20 MHz bandwidth. We are picking up the spike on both towers. But not all the time on the other tower. (see below) We are about 150 feet below a weather radar. I am wondering if they are having some malfunction. Is there a way to log the RF performance on the main page of the radio? If so, with what software? Having a log would allow us to figure out if there is any pattern to this and might help us figure out the source. Here are graphs that show the spikes on both ends of the backhaul. This first one is the tower that has the weather radar at the top. <http://community.ubnt.com/ubnt/attachments/ubnt/airMAX_AC/15193/1/BUC%20tower.JPG> http://community.ubnt.com/ubnt/attachments/ubnt/airMAX_AC/15193/1/BUC tower.JPG <http://community.ubnt.com/ubnt/attachments/ubnt/airMAX_AC/15193/2/WR%20%20tower.JPG> http://community.ubnt.com/ubnt/attachments/ubnt/airMAX_AC/15193/2/WR tower.JPG I've found several posts on spikes but those seemed to be continuous spikes, whereas these are random and can be closely or widely spaced apart. Has anyone seen anything like this? Anyone have any ideas? Patrick N.B. I’ve posted a thread on the Ubiquiti forum (http://community.ubnt.com/t5/airMAX-AC/Massive-Random-Interference-Spikes-R5-AC-PTP-US/m-p/1624513#M15219) but haven’t made much progress – hoping that someone here might have seen something similar. _______________________________________________ Ubnt_users mailing list Ubnt_users@wispa.org http://lists.wispa.org/mailman/listinfo/ubnt_users
