Download or read book Secret Spy Radio Stations written by Ronald Paul Milione and published by . This book was released on 2020-11-23 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABOUT NUMBER STATIONSThere are actually several types of number stations, but the prototypical one is simply someone on the air reading lists of numbers (or sending them via Morse code). Some read off other coded messages (like phonetic alphabet letters) or have sounds in the background that may or may not be digitally-encoded messages. One even used a sound clip from a Yosemite Sam cartoon to separate bursts of data! According to the Conet Project, number stations were heard as early as World War I. In most cases, no one knows for sure what the purpose of the stations are, but there are dedicated groups that try to locate them and even decode what they are saying. However, it is thought that most of them use some form of one time pad cryptography which makes trying to decode them a very long shot. It is pretty widely accepted, though, that the purpose of most (if not all) of these stations is to deliver clandestine messages.For example, suppose I wanted to send you secret messages so I give you a shortwave receiver. I tell you to listen to a certain frequency at a certain time and I read off a series of numbers. To decode my message, you treat the numbers I read as a page number followed by a word number in, for example, a newspaper that is a day or two old. As long as you keep a copy of the newspaper and you have the radio, I can send you messages that would be very hard to decipher unless someone told you what newspaper we agreed to use. This is a form of one time pad, and if you keep the secrets, the method is practically unbreakable. The key, though, is that when they search your hotel room and find a shortwave receiver and a few days of newspapers, that's not particularly suspicious. There's a group called ENIGMA 2000 that catalogs and analyzes number stations, producing the Enigma Control List (although the latest one is a few years old). They have a naming scheme that identifies stations based on language or other characteristics of the signal. For example, stations starting with E broadcast in English, while stations starting with S broadcast in a Slavic language. M stations use Morse code. Naturally, these are just handy designations (like E22). In most cases, we don't know what the stations call themselves. In 1998, the FBI arrested five Cuban intelligence officers. The spies received messages via a numbers station (using Sony shortwave radios) and the coded messages were a big part of the FBI's court case. The FBI acquired the software the spies used to decode the messages and were able to read them (and present them in court). This may be the only time that a government has admitted that these stations are tied to covert operations.The Cuban Five, also known as the Miami Five (Gerardo Hernández, Antonio Guerrero, Ramón Labañino, Fernando González, and René González) were tried and convicted of conspiracy to commit espionage, conspiracy to commit murder, acting as an agent of a foreign government, and other charges.WHY NOW?Numbers Station.. You have to wonder, in this day of Internet and satellite phones, why these stations still operate. After all, a shortwave receiver is a bit more unusual today than it used to be. Maybe the receivers are camouflaged as standard radios and need some James Bond-style gadget to put them on the shortwave band. After all, a satellite phone implies you are talking to someone and Internet usage is traceable. Short of being caught in the act (or using software like the Cubans), there's no proof of what you are listening to on a radio. Still, it seems incredible that there are apparently still operatives somewhere right now copying encoded instructions from these number stations. You can only wonder what they are up to.HOW CAN I HEAR THEM?If you have a software defined radio setup, that's perfect. Of course, a general coverage receiver or a ham radio that has a wide receive range will do the trick too. An easy way to find common stations!

Book Synopsis On the Short Waves, 1923-1945 by : Jerome S. Berg
Download or read book On the Short Waves, 1923-1945 written by Jerome S. Berg and published by McFarland. This book was released on 2007-03-28 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: As radio developed in the early 1920s, the focus for most people was the AM band and stations such as KDKA, the first broadcast station. There was, however, another broadcast method that was popular among many early enthusiasts--shortwave radio. As is true today, the transmission of news and entertainment programs over shortwave frequencies permitted reception over great distances. For many in America and beyond, shortwave was an exciting aspect of the new medium. Some still tune the shortwave bands to enjoy the programming. Others pursue broadcasts for the thrill of the hunt. This book fully covers shortwave broadcasting from its beginning through World War II. A technical history examining the medium's development and use tells the story of a listener community that spanned the globe. Included are overviews of the primary shortwave stations operating worldwide in the 1930s, along with clubs and competitions, publications and prizes. A rich collection of illustrations includes many QSLs, the cards that stations sent to acknowledge receipt of their transmissions and that are much prized by long-distance collectors.
