Stasi-MININT Connection
Oficina de Documentación
La Dirección de Inteligencia del Ministerio de Seguridad del Estado de la desaparecida República Democrática Alemana asesoró y suministró al espionaje cubano equipamiento para transmitir mensajes secretos númericos de acuerdo a documentos, desclasificados de los archivos de la Stasi, revisados por el autor durante la investigación "Conexión Habana-Berlín". Este método fue utilizado, de acuerdo a las investigaciones del FBI, por los espías Ana Belen Montes, Carlos and Elsa Alvarez y Walter Kendall Myers.
El documento proviene del archivo del Departamento Técnico-Operativo y se trata de una solicitud de la Dirección de Inteligencia(DGI) con fecha del 10 de enero de 1977.
El Mayor Herrera pedía el envío a La Habana de una estación numérica,( tipo 2028.3) con una frecuencia de 60 Hz, idioma español con cifras del 1 al 0 y la grabación con voz femenina: ATENCION,ADIOS y FINAL.
La información fue trasladada a Berlín por el oficial de enlace de la Stasi en La Habana, Coronel "Röster".
Cuban Agent Communications Failure of a Perfect System
DIRK RIJMENANTS
Abstract The Cuban Intelligence Service has a long record of broadcasting
encrypted numbers messages by shortwave radio to communicate with its
clandestine agents abroad. Although it is considered a secure way to
communicate covertly, there have been espionage cases where the use of this
type of communication provided hard physical evidence, resulting in criminal
complaints and convictions.

Cuban “Numbers Station” Spy Broadcast From Last Week
http://cubaconfidential.wordpress.com/2013/01/23/cuban-numbers-station-spy-broadcast-from-last-week/
" In this high-tech era of worldwide Internet connections and satellite
uplinks, an age when even junior-high kids are carrying cell phones, who
on Earth still listens to fusty old shortwave radios? Spies..."
" Rodeado de gráficos y mensajes confidenciales interceptados a
los agentes de la llamada ``Red Avispa'', Stuart Hoyt, quien durante años estuvo
al frente de una unidad de contrainteligencia del FBI dedicada al espionaje cubano,
explicó cómo los infiltrados de la isla se comunicaban a través de beepers,
establecían apartados postales para recibir informes y viajaban por el país
para encontrarse clandestinamente con diplomáticos cubanos....."
Name: Atencion Station
Reported Activity: Active
Country: Cuba
V2 Cuban Atencion Station Schedule
Thanks to Mark T, for this summary of the current V2c schedule as monitored and reported:
Time Mon Tue Wed Thu Fri Sat Sun
0900 7527 7520 7482 7482 7527 7520 7887
7527 7520 7887 8136
1000 7681 7887 7862 7681 7887 7975 7975
7520
1800 8097 8097 8097 8097
1900 8097 8097 8097
2000 7887 7887 7887 7887 7887 7887 7887
2100 6855 6855 6855 6855 6855 6855 6855
6797 6797
2200 6797 6797 6797 6797 6797 6797 6797
It is speculated that there are broadcasts at 1800 and 1900 on Mon, Tues.,
and 1900 Fri., but there have not been any reports I have seen for these
times. (Of course I could well have missed some reports.) My monitoring
has confirmed most of these frequencies / times as well as the reports.
All are in female, Spanish voice, AM; Call up is xxx xx for about 5 minutes,
to 5 number sets, with a 3 second pause after every 10 sets of numbers.
There does not seem to be a standard number of 5 number sets. (Although
someone who counts better than me may dispute that.)
Thanks to the many people who have monitored and reported to either
Enigma200, Spooks list, or Spynumbers data base for this report including
Mark S., Chris S., Tom H., Matthew F., and Don M. as well as others whom I
may have missed.
