I've noticed that simple having an antenna turned on, even if the range is turned _way_ down, is enough for the "So and so has detected a signal and is investigating" spawns.

I'd really love a flag to make that honor antenna distances. This would allow for using short-distance remotes, without calling NPCs, but would make long-distance remotes risky still. Even better would be a multiplication factor instead of a flag. "1" would be what I just described, "999999" would be basically the current behavior. "2" would mean NPCs could detect the antenna from 2x the distance the antenna is configured for.

Is this mod on github or anything? If so, I'd like to try to submit a PR. If not... consider it a suggestion. :)
