How do you deal deal with DFS channels?

Hi everyone.

Lately been having a battle with DFS channels in my setup. x2 APs either end of the property (single story bungalow). One side of the property has a neighbour. They (for some reason) appear to have 2 devices (potentially a router and a sky booster) both using 80Mhz wide channels on 5Ghz. Urgh. So the AP down that side of the property I have set to use a DFS channel. I've tried a few low DFS channels to escape the neighbours coverage (example below) and also a higher random one (100).

I've been thinking we're not exactly near anything so what could be around me...

1. I did some searching and found this weather station in the area (about 10 miles away) which apparently has coverage up to 150 miles! I'm guessing this could be the likely culprit?
2. Other things are Newcastle airport which is 12 miles away.
3. And apparently looking at some Ofcom information we have two military radars in the region but they appear to be about 40 miles away from me.

I was wondering what frequency range (or channel) could potentially avoid the weather station in particular? Or is it a case of just try them all? I am still on channel 60 monitoring the logs, but if it happens again I was going to go far end, and select channel 140 (I can't go higher than this).

Also, I was wondering for advice... I've dropped my channel width to 40Mhz from 80Mhz. Can I ask, if as above, the Radar signal is detected on channel 60 when I was using an 80Mhz slice, since dropping to 40Mhz, could that potentially have helped (I'm thinking less overlap now)? I've not seen an occurance in the logs again. So I was just curious if that could have helped.

I am going to speak with my neighbour, see if he can't either reduce down to 40Mhz or potentially remove one of the devices if unneeded. That would be a real help here.

Curious to see how others get on with DFS channels or do you try and avoid them?

Thanks

How dare you neighbour use 80Mhz width.
I'm using channel 149 for my 5ghz nothing else even close from my neighbours so nice and clear for my use.

I know right. It's a shame I can't select anything past 140 as you say, something in the 149, 153, 157, 161 and 165 would be a quick fix.

I forgot to mention in the first post, there's not really an issue with the DFS channel and how the AP handles the detection, the clients are moved and the AP will then change back to the set channel after a set time. But it's more that we use WiFi calling and so having the potential for choppy audio or drops isn't ideal (if using that AP at the end of the property).

I'm having some success on the highest channel I can select - ch136 with a 40Mhz slice. So far over the last 2 days, I've not seen any repeat of the Radar activity in the logs. So hopefully this will continue. I am looking into replacing the APs with a proper tri-band model to offer more flexibility.
