Numbers Stations, null messages

It is not possible to break the codes and get the meaning of the secret messages of the numbers stations, except for one type of messages. That is when there is nothing to say, a null message. Here are my primitive recordings of four different numbers stations with null messages. Sit back, relax and enjoy!


Spy Numbers Station, Enigma designation: E07

This is a recording that I made with my mobile telephone, (sorry for the inferior quality), of a spy numbers station on shortwave, run by the Russian Intelligence Agency GRU. The station is named E07 by the famous numbers stations monitoring group Enigma. The message, to the spy or agent, is coded and they are probably using so called one-time pads. That is, the key to the codes are only used once and therefore it is not possible to understand the message. OK, but why then are they using plain voice via a shortwave transmitter? After all, this is not the 20th century?

Elementary my dear Watson, It is impossible to trace the recipient this way, contrary to a message sent by regular mail or via the internet! As I have demonstrated by this simple video it is easy to listen to the coded messages even with a small shortwave radio!

Radio Sweden, 6065 kHz

Radio Sweden a

Radio Sweden b

In the glory days of international broadcasting, Radio Sweden were pretty prominent, both on 6065 kHz and om medium wave 1178/1179 kHz. In the early 70s there was a popular radio show late Saturday evenings, hosted by Kangaroo Kim and Big Bad Roger. (I think the latter is a professor now.)


IBRA Radio

IBRA is a Swedish based religious media company, belonging to the Pentecostal movement, (Pingströrelsen). During the glory days of Shortwave broadcasting they had their own produced programs in Swedish, as well as other languages, and also sold air-time to different evangelistic associations. They used the transmitters of Radio Trans Europe in Portugal. As a teenager I used to make tape recordings of the different programs. I still remember parts of the programs, for instance the last speech by the founder of the Pentecostal movement in Sweden Mr Lewi Pethrus. I also remember recordings with Pastor Jimmie Snow from the Grand Ole Opry, Nashville TN.



Polskie Radio, 6135 kHz

When I grew up during the Cold War there were at least a dozen different international shortwave stations that had transmissions in Swedish. Me and and a couple of my friends used old domestic radios with glowing tubes to pick up and listen to these transmissions after the school-day. It was very difficult to explain all this to our teachers. Polskie Radio, or “Polens Radio Warszawa”, as they were called in Swedish was one of those broadcasters, and one of the nicest. They read our letters on air, which was an incredible experience for a schoolboy, and we learned that Chopin was from Poland and we heard about the Warsaw Ghetto Uprising 1943…

It was a cold war, but Polskie Radio was one of the “softest” broadcasters from the other side of the Iron Curtain.

Now Radio Polonia has only shortwave transmissions in Polish, Belarussian and Russian, from transmitters in Bulgaria…

Radio Nederland, 9895 kHz

Radio Nederland, was not just another international shortwave broadcaster, it was an Institution, a Benchmark. Now the shortwave bands are empty without Radio Nederland. The programs were outstanding, the Happy Station Show, and the DX-program were unsurpassed in my opinion. Radio Nederland had a lot of publications in the field of shortwave listening, free on request! Radio Nederland, you have a special place in my heart…
