Broadcast Tower KB5

Broadcast Tower KB5 is high in the rocks just west of the Deathclaw Sanctuary. The drainage chamber just southeast of and beneath the tower has a copy of Tumblers Today just in front of an average locked door. Behind the door are random items (gas tank, pilot light) a Pre-War Book and some drugs, plus a bed. It is home to some Ghouls.

If you activate the tower, you receive Radio Signal Alfa Lima which is broadcasting morse code on a loop. However, if you travel into the drainage chamber stated above, there is a HAM Radio named "Radio Signal Alfa Lima" with a skeletal corpse sitting near, presumably the recorder.

Nearby
There's a random event next to the radio tower. One of the possibilities is having a refrigerator of purified water guarded by some wasteland settlers. You can leave, kill them for it, or use speech to split it.

To the West down the hill heading toward the highways, there is a camp of raiders fortified behind cars. There's a Grognak the Barbarian book (in a crate under tin cans), a Stealth Boy, a Super Sledge, and ammo chests & weapons.

North of raider camp / North West of KB5 tower on the bridge is a truck with a trailer containing a mini-nuke and other items.

Sometimes a Wasteland Merchant will appear here. A Scavenger may also appear here (accompanied by his Brahmin and his dog) selling a Nuka-Cola Quantum.
