fact, the simplest, cheapest, most portable transmitters would use VLF and morse code. It's something any 10 year old kid could rig, and you get excellent propagation all over the world. Hams use VLF around campfires just for kicks. And if you used it in burst mode with a pre-recorded tape or digital input of an encrypted message sent in morse -- who knows?

It has long been a cypherpunkly gedanken performance art project to build and deploy solar-powered bursting longwave transmitters driven by quality noise sources in the american deserts (or elsewhere). Extra points if you align them towards interesting landmarks.

Survival Research Labs will help us only if the Noise Fireflies attract bombing runs. Which they might.

Doesn't sound very difficult or expensive to make. Even easier would be Near IR emitters teasing overflights with sedition and libelous insults. Should fit in a small package. Could probably operate for a long time without attention. Any idea what sort of power levels would be needed to assure visibility? Lots of desolate hills around. Might be fun to see if they're even found...
