Node won't connect to any neighbors
I'm helping to set up a node on a roof tower here in West Seattle. The node can see lots of other nodes, but it won't seem to connect. We've dropped the LQM thresholds quite a lot, but even so I think we're above those thresholds. I'm not sure why none of these nodes are routeable. Does anyone have any thoughts?

Attached is the mesh status page screenshot. And here's the sysinfo.json?link_info=1&lqm=1 for reference:

Node won't connect to any neighbors
Reference:
https://www.arednmesh.org/sites/default/files/pmsv-mesh-status.pdf

NLQ OF 0% indicates
none of those 12 other stations on the same channel and bandwidth can hear W7AW-SeattlePMSV
.

I strongly urge you to not join a channel where there are already 12 nodes.

Suggested reading:

- especially:
"allocate different channels for specific geographic areas"

W7AW-SeattlePMSV: site elevation
Does the antenna, am-2g15-120, have a physical up tilt or down tilt?
If yes, how many degrees of physical up tilt or down tilt?
What is the height above ground of the am-2G15-120 antenna?
How far is the nearest and how far is the furthest intended downlink nodes?
Are all of the 12 indicated nodes withing the 120 degree beamwidth of the am-2g15-120 antenna?

Nightly
Try the latest nightly build instead of 3.24.4.0.  Those numbers look buggy based on known issues with that build.

That being said, yes you're only going to have success with 3 or 4 of those remote nodes.  These rest are just going to behave as interference.
