Recruitment radio beacon (radio station)
The frequency is generated by an antennae of the same name, which encourages wastelanders to inhabit the settlement in which it is set up. The message (detailed below) is on a continuous loop, interrupted by a random patriotic song after each loop; these songs are America the Beautiful, the Battle Hymn of the Republic, the Marines' Hymn, and The Stars and Stripes Forever.
Attention Commonwealth residents: uh, are you looking for a safe place to settle? Home in on these coordinates. If you're willing to work hard, you can make the Commonwealth a better place.”
