Spanish Language Numbers Station from 1966

The most active period of numbers stations monitoring began in 1980s as in efforts by “Havana Moon” or William (Bill) Thomas Godbey, Simon Mason and writers and editors of the “Monitoring Times” journal. Our site has studied numbers stations monitoring in 1980s. The great activity of numbers stations DX and monitoring lead to creation of online based groups like Enigma and Numbers and Oddities in early 1990s. However, number stations did not appear in 1980s, they been around since at least 1914. In their oldest simple form they started as Morse code transmissions, then live voice readings and finally automated voice transmissions, not stopping there yet as digital mode transmissions also hides numbers groups within.

The period before 1980s,1950s and 1960s were very active in terms of espionage. Many declassified documents tell us about CIA and SIS operations in Baltic States, Soviet Union and Eastern Europe and elsewhere using Morse code messages. Then there is a case of Operation SOLO of FBI infiltration in the American Communist Party and Soviet secret service, where numbers transmissions from the Soviet Union were involved.

Numbers stations were in the air and there were people listening to them. So this brings to the subject of this article: a authentic tape recording of several transmissions of Spanish language Five Digit numbers station recorded in 1966.

The recording was made by Don Hibschweiler, who is currently a morning radio host on 90.1 WFYI Public Radio.

As Don describes “the broadcasts were daily at 1700 EST on 6.805 Mhz. The recording was made on July 20, 1966 at my listening post in West Central Indiana. There are Spanish numbers in groups of five.  He always slowed down during the last set of numbers and then says something like, “Toonigh, toonigh”. I also heard one broadcast where the announcer made a mistake.  The broadcast was repeated later with the same mistake and a weaker signal.  I thought this meant the second broadcast was a recording of the first or both were recorded ahead of time.  Also, the difference in signal strength may indicate the use of a directional antenna and/or a different transmitter power.”.

What we have here is a recording of supposedly male voice Spanish language numbers station. The technical issues and specifics of the broadcasts may point to Cuba. Cubans in 1980s to early 2010s used voiced five figure stations with characteristic“Atencion” at the start of the broadcast. This is was known as V02 and V02a before moving on to hybrid digital and voice station HM01  This station however has no such prefixes. It could be old predecessor to Antencion station. CIA was caught using four figure numbers station in Spanish language, so CIA involvement  also cannot be ruled out.

Mr Don Hibschweiler came across this station after reading an article on “Electronics Illustrated” 1966 May issue.

The article is called “How to eavesdrop on real spies” featured real use of numbers stations and radio signal announcements as of case of Bay of Pigs invasion and the Rudolf Abel the Russian spy. It also featured some of the frequencies used by the numbers stations back then and the time of broadcast. Thanks to this journal Don was able to tune into this Spanish language number station.

The article points to various other numbers stations used in 1966. The German language station peculiarly plays “The March of the River Kwai” and classical music piece by Strauss as its interval signal. Such station has not been heard and any recording of such would be welcomed. 

In the 1960s the first automatic voice machines were developed. In the decade they spread also to Eastern Block. Automated voice creation improved numbers stations as the errors made during live reading were common. Cuba also eventually started using automatic voice transmissions, but this 1966 recording still indicates live or pre-recorded broadcast. 

This recorded Spanish language numbers station as for now stands unidentified until new documents pointing to it are found. This is one of the oldest recording of a number station publicly available and stands as important radio history source.

Many thanks to Numbers Station Research and Information Center and Don Hibschweiller for allowing us to republish this article and share this excellent recording.

Many thanks to SRAA contributor, Tom Garavas, who shares the following recording and notes:

Radio Sandino, Nicaraguan clandestine radio station, voice of the Sandinista National Liberation Front. Recorded the day Anastasio Somoza DeBayle resigned the presidency and fled to Miami.

The following is a translation of the first two minutes of the announcement:

"Somoza is leaving. During these moments, [inaudible]. No one shall act freely. Everyone should act under orders of the one responsible [over them], under instruction of the national joint leadership, FSLN (Sandinista National Liberation Front). We must prevent, at all costs, the individual energy and [inaudible]. The FSLN guarantees publicly and emphatically to respect life and physical integrity of all military and their families once this fight is over. Nicaraguan brothers, abiding by the provisions of the new government, FSLN, reaffirms publicly that executions will not be allowed, nor physical violence against those military members who comply with the orders to ceasefire. Denying disseminated malicious versions by the Somoza [government], the new government of national reconstruction guarantees that the death penalty shall not apply to any military member guilty or not of a crime. The ordinary courts of justice will be the ones who will recognize [inaudible] and judgement. We alert all of the honest officers of the national guard that the Somoza Security Office has initiated a fierce persecution against all honest officers. We call upon you to not let them, and to trust in the guarantee the new government of national reconstruction offers you. We reiterate that every honest officer can integrate to the new patriotic military. We know that many military members have not had the opportunity to get out of the Somoza military. To those, we ask to have confidence in the imminent victory."

This recording was made on July 17, 1979 at 0500 UTC in Plymouth, MN (USA) using a Hammarlund HQ-180 and longwire antenna.

Here is a recording of La Voz Del Llano on 6,115 kHz from 2 September 1984. The first part is about 10 minutes, the second is 2 hours and 15 minutes. It was originally recorded on an open reel tape at 1 7/8 ips.

Radio Enciclopedia: August 8, 2017

Radio Enciclopedia, logo 1.jpg

Live, off-air, one-and-a-half-hour excerpt of an almost four-hour recording of Radio Cubana's AM radio station CMBQ, Radio Enciclopedia, Havana, Cuba, on 8 August 2017 beginning at about 18:30 UTC. The station operates on an frequency of 530 kHz from a transmitter in the Villa María area of Havana with a power of 10 kW and an omnidirectional antenna.

The transmission was received on a Tecsun PL-880 receiver with its built-in ferrite-bar-loop antenna in Naples, Florida, in AM mode with 5 kHz RF filtering. Reception was fairly good although there was co-channel interference from a Radio Rebelde transmitter in Caribe on Isla de la Juventud, which is in the same direction as Havana as seen from Naples.

Radio Enciclopedia is an easy-listening music station with pieces interspersed with music descriptions and brief encyclopedic tidbits read by female announcers.

The recorded program is "La Tarde Contigo."

Radio Ciudad de La Habana: August 14, 2017

CMCA-LOGO-cuad-hi-res.jpg

Live, off-air, one-and-a-half-hour excerpt of a five-and-a-half-hour recording of Radio Cubana's AM radio station CMBE, Radio Ciudad de la Habana, Havana, Cuba, on 14 August 2017 beginning at 21:00 UTC. The station operates on an frequency of 820 kHz from a transmitter in the Arroyo Arenas area of Havana with a power of 10 kW and an omnidirectional antenna. There is some confusion about the correct current call letters of the station. Government documents state CMBE, while other sources state CMBU. On air, the station uses CMCA and these were the official call letters in the past when the station used a different transmitter site.

The transmission was received on a Tecsun PL-880 receiver with its built-in ferrite-bar-loop antenna in Naples, Florida, in AM mode with 5 kHz RF filtering. Reception was fairly good although the signal is a bit weak initially and there is some atmospheric noise due to thundershowers and thunderstorms in the Naples area. The transmitter went off the air a few seconds before the end of the recording and didn't return for about five minutes.

Radio Ciudad de la Habana, or simply Radio Ciudad, is a youth-oriented radio station with an emphasis on cultural and musical programming.

The recorded programs are "Diario Hablado" and "Rapsodia Latina."

Radio Colosal: April 16, 1980

Many thanks to SRAA contributor Paul Harner for the following recordings. Paul notes:

Radio Colosal de Neiva (Colombia) was one of the more reliable signals to be found on 60 meters where I live.  The station was an affiliate of the TODELAR network, and broadcast on 4945 kHz.  Within a year of this recording, Radio Colosal disappeared and the frequency became part of the Caracol network.

Ecos del Torbes: March 1980 (2 Parts)

Many thanks to SRAA contributor, Paul Harner, who notes:

Broadcasting from San Cristobal, Venezuela on 4980 kHz, Ecos del Torbes was well heard in midwestern North America in the evenings and early mornings.  Here is a recording of the station from the 11 PM hour (local time) in the spring of 1980.
There is a pleasant mix of English and Spanish language pop, featuring several Venezuelan artists in this aircheck.  There is also a brief newscast in the second half of the recording.  If anyone out there has a better understanding of Spanish than myself, I would like to know the specific headlines, as it would help me get the precise date this recording was made.

La Voz de Huila: April 27, 1980 (2 parts)

Many thanks to SRAA contributor, Paul Harner, who notes:

In 1980, Daylight Saving Time began on the 27'th of April.  When I was in high school, the Saturday night overnight hours were a favorite time for me to listen to shortwave signals.  Especially the domestic Latin American stations on 49 and 60 meters.
On that night, two stations from Colombia were coming in reasonably well, and I decided to record an hour of each of them.
Based in the city of Neiva, "La Voz de Huila" was an affiliate of the TODELAR network ('Primeros en sintonia').  One could easily identify stations from this network through their top of the hour ID's (they used chimes similar to the NBC network in the USA).  The station's frequency was 6150 kHz.
Here is a recording of "La Voz de Huila," taken during the 4 AM hour (local time) on 27 April 1980

La Voz del Llano: April 27, 1980 (2 parts)

Many thanks to SRAA contributor, Paul Harner, who notes:

In 1980, Daylight Saving Time began on the 27th of April.  When I was in high school, the Saturday night overnight hours were a favorite time for me to listen to shortwave signals.  Especially the domestic Latin American stations on 49 and 60 meters.
On that night, two stations from Colombia were coming in reasonably well, and I decided to record an hour of each of them.
It was the first time I ever listened to "La Voz del Llano" in VIllavicencio.  Over the years that station became a favorite of mine.  The station introduced me to music from Colombia.  The music was fast paced, and fun, and so were the promos.  La Voz del Llano was an affiliate of La Cadena Super ('Orgullosamente Colombiana'), and it's 10 kW signal could be heard well most nights.  Their frequency was 6115 kHz, but they tended to vary from that frequency.
Here is a recording of "La Voz del Llano," during the 3 AM hour (local time) on 27 April 1980.

Paul also noted that these recordings were transferred from magnetic tape (pictured above) which had become somewhat damaged over time. We appreciate the effort he has put into transferring this audio and sharing it with us here on the SRAA:

Radio Havana Cuba, Barack Obama and Raúl Castro Press Conference in Cuba: March 21, 2016

The following off-air recording of Radio Havana Cuba was made on March 21, 2016, starting a couple of minutes prior to 1800 UTC on 11,670 kHz (at an AM bandwidth of 12.5 kHz). This was a historic event: the first time a US president has visited Cuba in over 8 decades. The following recording includes the live coverage of the Obama/Casto press conference, followed by one hour of RHC's English language service and a part of RHC's French language service.

The receiver used was a WinRadio Excalibur connected to a Pixel Loop Pro magnetic loop antenna. Location received was North Carolina.

Radio Reloj: August 30, 2015

Many thanks to SRAA contributor, Richard Langley, who notes:

Live recording of Radio Reloj (CMBD), Havana, Cuba, on 30 August 2015 beginning at about 15:55 UTC on a frequency of 950 kHz. The signal originates from a 10 kW transmitter at Arroyo Arenas / San Augustin, near Havana, using the Centros Transmisores de Ondas Medias 1 (CTOM1) non-directional antenna facility.

(Radio Reloj can be heard on various frequencies in the AM and FM bands in Cuba and live on the Internet at http://media.enet.cu/radioreloj.) 

The recording, in Spanish, is a typical Radio Reloj broadcast with two announcers alternately reading news bulletins accompanied by time signals. The announcers identify the station and verbally give the local time each minute. In addition to the verbal station identification, each minute either the letters RR in morse code (using 1800 Hz tones) are transmitted or five-note chimes (D4, G4, B4, D5, B4) are played. The chimes sound like those of a dinner chime or even some door bells and are reminiscent of the U.S. National Broadcasting Company (NBC) chimes. On a couple of occasions in this recording, during a particular minute, neither the morse code nor the chimes are used and sometimes, during a particular minute, both are used. In this recording, we can also hear at some minutes pairs of tones being played going up and down the scale as news headlines are read. On other occasions, three- and four-note chimes in various sequences have been heard (perhaps at the announcers' whim).

Different tones identify each second, minute, and five-minute epochs. Based on measurements, each second is marked with a "seconds tick" consisting 10 cycles of a 1000 Hz tone (0.01 seconds duration). Minutes, except for multiples of 5 minutes, are marked by 172 cycles of a 1000 Hz tone (0.172 seconds duration). Every 5 minutes, the marker is extended to 672 cycles of a 1000 Hz tone (0.672 seconds duration). The minute and 5-minute markers are preceded by 5 cycles of a 1000 Hz tone, followed by 0.013 seconds of silence.

The time signals in this particular broadcast were well within one second of the time given by a computer's clock synchronized to the U.S. time standard using Network Time Protocol. 

The broadcast was received on a Tecsun PL-880 receiver with its built-in loop antenna in Key West, Florida, using an RF bandwidth of 5 kHz. The receiver was oriented for maximum signal strength. Signal quality is generally good. However, there are repeated static crashes (QRN) from thunderstorms in the region.

Richard also notes that he was located in Key West, Florida, using  a "Tecsun PL-880 receiver with built-in loop antenna using an RF bandwidth of 5 kHz. The receiver was oriented for maximum signal strength."
