Too many post apoc films recently haha.
TSHTF, and there's a massive die off.
After 3 weeks post die-off, your radio signal picks something up.
What do you do if:
a. It's a military signal declaring a safe zone. Coordinates provided
b. It's a distress signal, coordinates provided.
c. It's a call to unite for safety. Time to meet, and coordinates provided?
What caused the die off? It will make a difference.
If the die off were due to terrorist NBC attack I might cautiously approach the military signal coordinates, recon and decide from there.
The civilian calls I would ignore no matter what the cause or problem.
I would not reply by radio to any of the signals due to triangulation and discovery possibilities.
I'm with Mort...possibly go look at the coordinates from a safe distance with a .308 but I wouldn't respond on the grounds of they will be more vigilant if they know someones out there and they may have df ed you
I'd just ignore them unless I was in dire need of medical assistance or something.
A few extra weeks of living as you have won't kill you. If it looks like it may, then you go.
I would probably attempt to gather intel by recon to assess if they are a threat or an asset. No way would I respond to their message, that gives away my advantage, any contact would be on my terms and at my time of choosing.
Of course if it was the Swedish under twenties net ball team then I might just help.
Intel is more likely to be by hear others respond and the follow up from that. SO you will need to be listening for most of the day.

It's only a trap if you do not know it is there.
