If a civilization was exponentially more advanced yet still didn't have FTL travel (or FTL communication) might they harness such a galaxy-level radio signal as a beacon?
All you'd have to do at that point is figure out how to make it blink in a pattern by intermittently blocking it
Might take centuries for others to receive but it could be a historical record.
