NÃistà on koetettu etsià salakirjoituksen avainta ja metodia - mutta
turhaan. Kaikki eivÃt ehkà ole salakirjoitusta lainkaan, vaan ns.
yhden kÃyttÃkerran avaimia. Ja esim. hÃmÃÃmistarkoituksessa
kahdessakymmenessà 5 merkin numerosarjassa voi merkitsevÃnà olla
vain yksi sarja. MÃÃrÃtty numerosarja voi tarkoittaa jotain
kokonaisuutta ... jonka tarkoitus on vastaanottajalla selvillÃ. Vrt.
esim. toisen maailmansodan aikana BBC:n radioteitse lÃhettÃmÃn
"ilmoitukset" (esim. milloin Normandian maihinnousu alkoi).
Kovasti nÃmà "numerotÃdit" ovat vÃhentyneet ... on kaiketi keksitty
hieman nopeampia tapoja hoitaa viestintÃÃ - esim. satelliittien
kautta: laitteet ovat pienikokoisia ja eivÃt lÃhistÃllÃkÃÃn muiden
kuunneltavissa. Ja antenni saadaan hyvin piiloon muiden
satelliittiantennien sekaan.
Aihepiiristà lÃytyy melkoisesti lÃhdekirjoituksia - varsinaista
totuutta on nÃistà vaikea lÃytÃÃ, pÃÃasiassa kuitenkin vain
olettamuksia.

Tutultahan tuo saksalainen leidi kuulosti: "achtung, sieben eins sieben..."

EivÃtkÃs nÃmÃkin jo liene siirtyneet digitaalisiin lÃhetteisiin?
Sellainen ei herÃttÃisi juuri mitÃÃn huomiota satunnaisessa kuulijassa.
Hauska huomio, ettà eivÃt ole luottaneet itÃblokin

The Secret Machine Behind Soviet Numbers Stations By Paul Riismandel
on October 20, 2014 in History, International
I recently learned of a series of YouTube videos that show a German
machine that is alleged to be the voice behind Soviet cold war
numbers stations. The videos, uploaded four years ago, show
something that looks like a piece of electronic lab equipment that
emits a sampled or synthesized voice rattling off a programmed
sequence of numbers. According to the accompanying description, the
voice comes from swappable program chips, and the machines are
owned by a German spy-gadget collector.
For the uninitiated, numbers stations are shortwave broadcasters
that transmit nothing but sequences of numbers read in a monotone
voice, in any number of languages. It was long thought that the
stations were sending coded instructions to spies and other foreign
agents in the field, and recent evidence and declassified documents
show this to be true. During the cold war they were nearly
ubiquitous on the shortwave dial, and persisted after the fall of
the Soviet Union. Though they are less common now than they were
even twenty years ago, shortwave listeners can still find them
relatively easily.
The machine in these videos speaks in Spanish and German, or can
play morse code. It can be programmed manually through a number pad
or by using a punched tape that looks like a miniature player-piano
roll, clearly indicating that this is a piece of 1980s Soviet tech.
Shots of the machineâs guts show Zilog Z80 microprocessors, which
were popular CPUs for home and business microcomputers in the late
70s and early 80s. Curiously, all the parts, ports and the display
are labeled in English.
The creator of the videos is a IT security professional from the
Netherlands named Peter Staal, who has also given several lectures
on the topic of numbers stations. One of his lectures from 2011
given at Delft University of Technology is available on YouTube.
His PowerPoint slide deck is also available on SlideShare.
