Sean asks the stations contacted that he's looking to investigate cross-border threats to inhabitants of Vermont. He probably does not get anything useful and tries to contact the stations further away. If any operator outside of the state is contacted, Sean wants to chat about the general life conditions of the parties on both ends of the comm:
1. Who they are (we are Radar Base Guys).
2. What's troubling them, if anything (we have a number of problems, of which organized Slavers/Raiders, unnatural mutated animals and potentially rogue Shelters are the most prominent at the moment).
3. Any major local powers (we mostly have regional gangs, but the Slavers and rogue shelters are potentially cross-border, also, we've heard of "The Sacred Snakes", but don't know who they are).
4. Anything they want to discuss.

See HT38 sidebar and B38 about short-wave communications, if we have them. If not, the range to a medium TL8 radio with an extensive antenna would be up to 210 + N*10% miles by voice or 3..10 times that by code, where N would be the operator's margin of success. Less fancy stations would be more difficult to reach, but still posible when talking by code (most likely Morse for TL7 or less).
