Miller family radio signal

Miller family radio station is a radio station in Fallout 4. It can be picked up after extending the satellites at relay tower 0SC-527. It is a distress signal from someone hiding inside 'Big' John Miller's bunker, who explains how to open the bunker's sealed entrance, as well as its location, before interrupting himself to reassure John's daughter, Kimmy Miller.

Location
The origin of the broadcast is a ham radio in a shelter at Big John's Salvage. The hatch is in a tipped train car in the junkyard but is, as mentioned in the broadcast, shut tight. The hatch can be opened by flipping the circuit breaker in the hardware store slightly to the north of the main building.

Appearances
The Miller family radio signal appears only in Fallout 4.

Bugs
The bunker may become sealed again after exit. The generator has already been switched on, so there is no way to enter the bunker besides using console.
 * Possible solution, open the console and type: coc bigjohnssalvage01 and hit Enter. Turn the ham radio off (not just regular radio), climb out using ladder.
