You know the drill, after setting up a settlement your next task will be to go to some high ground and placing a receiver so the aforementioned settlement can get the news. In the case of Kadara, the receiver site if east, southeast of the settlement, but to actually make your way around Kadara’s pointy mountains and reach the navpoint you’ll want to approach the navpoint from the south. When you find your way up to the heights the navpoint directs you to, merely approach the scattered crates and activate the Receiver.
