Re: [DX] About numbers stations
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 viestintÃà - 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.

Aihe: Re: [DX] About numbers stations
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 mikroprosessoreihin, kun vehkeessà on Z80.

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.

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.

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.

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.
