Signal Yankee Bravo

Signal Yankee Bravo is a radio transmission just south of Canterbury Commons and southwest of Robot Repair Center which is activated by a switch on a transformer there. Although identified as "Signal Yankee Bravo", it actually broadcasts the sound of labored, heavy breathing.

Just west of the tower, at the base of the drop-off, is a sewer grate to a Drainage Chamber. On entering, the door to the right leads to feral ghouls (and possibly a Glowing One at higher levels) hovering around a ham radio, making them responsible for the broadcast. The ghoul sounds can still be heard in the signal even after the ghouls are killed, even if you turn the radio off ("click"), then back on. (You have to select the station on your Pipboy again.)

There is also a large hole in the wall to the left from the entrance that leads to a small cavern with several feral ghouls and a Glowing One (also depending on your current level). There is nothing of note in this room except a very strongly radioactive junk pile in the far corner.

Bugs

 * The game may crash upon selecting the station from the Pipboy (Tested on patched PC version)
 * Even once you killed both ghouls by the Ham&#160;Radio, you can still hear the heavy breathing.

Video
DiT5DRZnf0U Note that this video does not show you where the drainage chamber with the ghouls is (it's directly off the cliff to the right of the tower when coming at it from the Enclave Camp) but it does show where the tower itself is. Directly at the 3-way center between the Robot Repair Center, Vault 108 and Corvega Factory literally a few feet from the RHO Experiment Enclave camp. This radio signal is often viewed as one of Fallout 3's more creepy moments, right alongside the Dunwich Building and Vault 106 etc due to the sound the ghouls make over the broadcast.
