The oldest radio signaling method was used to send messages between people in Egypt according to this article at the Huffington Post. The link was in a Democratic Underground post that J. Neil Schulman forwarded to me in email.
“These messages weren’t coming from mobile phones or computers, but from an amateur radio sending out Morse Code somewhere amidst the chaos in Egypt.”
Hundreds of miles range with a few watts using a wire thrown over a tree branch for an antenna can beat the government kill switch.
Meanwhile, on the political right side of survivalist prepping, Alex Jones InfoWars published a credible list of alternative communication methods from Liberty News Online, “How to Communicate if the Government Shut Down the Internet” (also forwarded to me by J. Neil Schulman).
Just one point of clarification. During a political upheaval, checking the call sign of amateur radio operators won’t be the State’s top priority and effectively jamming all signals might not be possible, especially if one were to use spread spectrum techniques.
Let’s say for example you were to transmit thermal noise in one band and the noise mixed with the message in another (transmitted reference). It would appear to be noise as well.
Perhaps if you have some programming skills you could use the digital “direct sequence” method to mix several pseudo random “chip bits” with each bit of your message while you quickly hop the center frequency of your signal using a fast digital synthesis chip and a secure software spreading code.
And just to be safe you might use a stealthy hidden antenna that looks like a clothes line, basketball hoop, bird feeder, flag pole or other disguise so your neighbors don’t rat you out. Out of sight, out of mind. Morse code and texting can be done silently with earphones. QSL?
Victory over censorship!
