Making contact by FM radio

[Skvez]

I have *some* experience with transmitters, I don't claim to have a lot.

Certainly the ideal scenario is that everyone you want to communicate with has the same (obscure) transceiver but realistically that's very unlikely outside your own small group.
My original question was asking what worth people saw in being able to contact others by a medium that almost all people already have.
What it could be used for (and whether this is worth the OPSEC risk) was supposed to be the point of this thread. I'd love to hear peoples' opinions of HAM radios on another thread but that wasn't the point of this one.
An FM broadcast over a small area could be used for
1] Warning of gangs or refugees entering the area
2] Voice of the Village - tell people how to collect water and other basic survival info without having to identify yourself and risk the locals overpowering you by numbers for your stuff. I'm sure there will be lots of discussion on this one as to whether we want the slightly-better-than-sheeple to survive a bit longer (prolonging their suffering) or just let them die quickly.

For contacting other groups if you have CB and they have Ham you're not going to be able to communicate but pretty much everyone will have a standard 88-108MHz FM receiver. You could even use this band to tell people where to find you on the more obscure bands.

Why do you (NR) think the risk of being triangulated while broadcasting over a small area is 'very high'? Most people don't know how to triangulate and the authorities/military and unlikely to pick up a weak localised transmission.
