In Gulf War I, AWACS aircraft would send targeting information to aircraft and ground-based artillery to take out convoys. The targeting was only for trucks laden with cargo. The AWACS could tell the difference based upon the difference in the electrical ignition noises made by a laboring engine. The AWACS instrumentation is cryogenic in order to attain near-theoretical sensitivity of both optic and radio equipment.

If you make weak enough radio signal to be heard but a short distance, you'd be better off just passing a note or talking to the recipient. When the SHTF, you won't be traveling at 50-60 mph because you will prohibited from doing so. The US military can hit moving vehicles with a single shot; and, plenty of evidence was shown about that in GW I & II.

I know the science of radio.

I suggest that clusters of people learn to make and use scratchpad cyphers and establish old-fashioned "drop boxes". Electronic surveillance is well beyond what most people think.

I guess I’m thinking more along the lines of who will be in control of the military hardware, Gingis. Our military men and women today will not likely be at the helm of these modern war machines, as they’ll have been drummed out of the military by the faggots and communists.

I’m not disagreeing with you, but for brief, coded communications over a large metro, radio is the way to go.

I don’t disagree with the idea of sneakernet, but that only works for local communications. If you need to relay across a metro or a region, radio is the only way that can work.
