When you flip the switch at broadcast tower KB5, the Alfa Lima signal becomes active.
The Morse code translation of the broadcast is:
CQ CQ CQ DE AL AL AL K
This translates to "All stations this net, all stations this net, all stations this net, this is... Alfa Lima...Alfa Lima...Alfa Lima...Stop/Over." It is emanating from one of nine encoded broadcasting stations.
If you go east-southeast of the tower and drop off a small cliff, you will land practically on top of a sewer grate to a drainage chamber. Once you enter, you will find an average locked door. There is also a skeleton here with a 10mm pistol, bobby pin, and a Tumblers Today. Inside will be some supplies including a pre-War book and motorcycle parts. As with all the Drainage Chamber stations, there is a Ham radio that lets you toggle the broadcast.
