Signal Sierra Victor

A radio transmission located southeast of Jocko's Pop & Gas Stop. The large antenna tower near the station entrance can be turned on with a lever on the transformer at its base. Once the power is restored, it begins broadcasting Morse code. The station generating the transmission is in a Drainage Chamber reached via a manhole. The manhole is at the far end of the downed radio tower (right next to the broadcasting antenna), to the east.

Morse code translation:

CQ CQ CQ DE SV SV SV K

This translates to "calling anyone, this is Sierra Victor, over". For more on the nine stations broadcasting Morse code, see this.

The broadcaster seems to have set a number of traps and barricaded himself in the room before expiring. From the looks of it, he was working on something on the table when it exploded in his face.

Be warned, a Deathclaw has been spotted in the canyon in this area.

Traps
This is quite dangerous location due to several very nicely placed traps, providing an entertaining challenge for explosives experts.
 * In the entrance corridor there are two pressure plates placed on the crossing with collapsed tunnel. They trigger two rigged shotguns.
 * Up further the path is blocked by a barricade made with some arms cabinets and a barrel. The barrel is the only movable object here. Right behind the barrel there is a grenade bouquet trap. You can try to move the barrel (using 'Z' on the PC) to lay it down and then reach the trap to disarm it. Alternatively, gingerly jump onto the cabinet (without bumping into the barrel), and you can directly reach the bouquet. The barrel cannot be dragged back towards you, and pushing it forward will trigger the trap. The trap is very effective in this tiny space, and even if you retreat halfway up the corridor, you can still be injured by fragments. The easiest way to get past this trap is to throw a grenade down the corridor.
 * Left corridor is rigged with two frag mines just in front of the door.
 * Right corridor is clear.
 * Inside the main room there is only one trap - a rigged terminal. The trap is activated by using the terminal, NOT by getting close to it. To defuse it you have to walk around and reach the back panel.

Notable loot

 * A Mini Nuke
 * A copy of "Duck and Cover!"
 * A bottlecap mine
 * An assault rifle
 * A few bottles of purified water
 * Other stuff including cherry bombs, ammo, mines and some junk.

Trivia
There is a wrecked car on the cliff near the transmission tower with two skeletal corpses and some empty whiskey bottles lying on the hood. Apparently a couple of lovers were enjoying the view of Tenpenny Tower when the bombs fell.
