Cuban Spy Communications Intercepted Yesterday 3

A shortwave radio (High Frequency) enthusiast recorded this “Numbers Station” broadcast yesterday. Thirty-two seconds into the video, you will hear distinct tones before the automated female voice begins the broadcast.

In the past, a “Numbers Station” broadcast would always consist of 150 five-number groups. Over time, Havana migrated to this hybrid broadcast, consisting of sporadic voice laced together with the digital transmission of compressed data. This evolution both lessens the possibility of errors made by the receiving spy and allows for the transfer of infinitely more information. The Cuban spy will use a cipher program to automatically decrypt and decompress the recorded digital signal.

  1. Hello Chris. I see that you have used two of my videos on this blog post. I have no problem with it, but it would had been nice if you linked this post to me. I am rather interested in number stations and other shortwave radio oddities.
