The Narrowband Signal
A late-game radio-focused observatory can detect an artificial narrowband transmission. The current published story requirement is heavily weighted toward high-level radio science.
First Contact
An Impossible Signal
Your radio array has detected a narrowband transmission repeating from an empty patch of sky. The pattern is artificial, stable, and not in any known human band. The science team wants authorization to build a protected signal-containment and decoding structure before the next observing window closes.
