The Numbers Stations Analyzed, Discussed

GMontag wrote to mention a Washington Post article about the always-intriguing 'number' radio broadcasts. The numbers stations, as they are known, are 'hiding in plain sight' spycraft. Random digits broadcast at little-used frequencies are known to be intelligence agencies broadcasting their secrets in encrypted form. The Post article gives a nice run-down on the truth behind the transmissions, and touches a bit on the odd community that has grown fascinated by them. From the article: "On 6840 kHz, you may hear a voice reading groups of letters. That's a station nicknamed 'E10,' thought to be Israel's Mossad intelligence. Chris Smolinski runs SpyNumbers.com and the 'Spooks' e-mail list, where 'number stations' hobbyists log hundreds of shortwave messages transmitted every month. 'It's like a puzzle. They're mystery stations,' explained Smolinski, who has tracked the spy broadcasts for 30 years." This article made me recall a great All Things Considered story from a few years back about Akin Fernandez's 'Numbers' CD, a CD compilation of some of the most interesting strings of randomly read numbers reaching out across the airwaves.

A quantum computer is useless against a message encrypted with a properly constructed one-time pad.

You're correct, but just in the interests of preventing confusion, the idea of what was a "long wave" in the early 20th century was very different from what an electrical engineer might think of today. What are today rather low frequencies for radio communication were at the time rather high, hence the term 'short waves.' The preferred frequencies for communication at the time are now barely used by anyone, with the possible exception of naval communication with submarines and the like. Their data-carrying capacity is just too low, and the antennas they require are obnoxiously large.

Of course, by calling things in the 1-30 MHz range "high frequency," those engineers forced us to use such terms as "very high frequency," and "ultra high frequency" when equipment finally became capable of transmitting at those wavelengths.
