I like the radio idea. It brings to mind the good old days of pirate radio stations.
As for the objections regarding the of locating radio transmissions by adversaries, as technology becomes cheaper and more miniaturized, it will become more and more feasible to have very small, very cheap, disposable repeaters, which could be deployed on mobile, relatively anonymous transport (like flying drones, trains, and ships), and perhaps automatically activated long after their owner has left.. and perhaps activated only in case of emergencies, like this blackout.
Individuals wishing to communicate through these repeaters could send very short and rare transmissions from different, and maybe also mobile locations, so that finding them will be much more difficult.
Unfortunately, if adversaries are aware of these devices (and they would be were such devices to ever become widely deployed), they could still either jam them or perform a denial of service attack by flooding them with their own transmissions. Some sort of steganography might be of use here, but I'm not sure how effective it would be if lots of people know about it, which is a requirement for any widely deployed technology.
