[Battlemesh] Questions for a weather radar specialist?

[Zachary Giles]

Very interesting; We just finished with this problem in the US ( New
York City ) as of today after they shut down a couple of our sites a
few days ago. The equipment that interfered was also Ubiquiti.

The confusing part is: We are using DFS compatible equipment and are
at proper power levels; but it appears not to work. Moreover it's a
bit hard to tell what we're supposed to do: not use those frequencies
at all, or use them carefully? It kindof seems like the former ( not
at all ) within 35km of the radar.

I'd be curious what the experts have to say about compatible equipment
and the failure of them; I'd also be curious to hear about how to make
various brands ( like Ubnt ) not even try those channels if we really
aren't supposed to use them.

(I'll add to the Pad, just thought I'd throw in some words )
