Broadcaster: Radio Canada International Interval Signal Series 1970's

Date of recording: Circa 1970s

Frequency: 9.625 MHz

Reception location: Ancaster, Ontario, Canada

Receiver and antenna: Hallicrafters S-52 or Realistic DX-150A and a longwire antenna

Notes: Back in the early 1970s, Radio Canada International ran a very popular interval signal series on their SWL Digest program. This was hopefully to help DXer's identify that sought after station. I recall recording a few of these programs, and while going over one of my old cassette tapes recently, I came across a segment where they were presenting a number of African interval signals. Subsequently, I have uncovered five additional segments, or at least, portions of them. As these were originally recorded with an open mike to the speaker of the receiver, some room noise (voices) may be detected, as well as small amounts of unedited material near the ends of some of the segments. These were recorded at Ancaster, Ontario, Canada, likely on 9625 kHz.

Radio Metropolitana: November 10, 2022

/

Live, off-air, three-hour excerpt of a recording of the provincial Cuban station Radio Metropolitana, CMBL, Havana, Cuba, on 10 November 2022 beginning at about 20:00 UTC. The station operates on an frequency of 910 kHz from a transmitter in the Villa Maria area of the Distrito de Guanabacoa municipality of Havana with a power of 5 kW and an omnidirectional antenna. The station also transmits on 98.3 MHz in the FM band.

The transmission was received on a Tecsun PL-880 portable receiver with its built-in ferrite-bar-loop antenna in Marathon, Florida, in AM mode with 2.3 kHz RF filtering. Reception was fairly good with some background noise due to the slightly weak signal associated with the over 200 km long-range reception.

Radio Metropolitana is part of the group of stations that make up the Provincial Directorate of Radio in Havana with studios in the FOCSA building in Havana's Vedado district. It is on the air 24 hours a day and offers cultural programming with a strong presence of music aimed at families in the capital city. Its slogan is "La radio de casa" and its theme tune is a fragment of the familiar song "El Manisero" ("The Peanut Vendor") by Cuban composer Moisés Simons. Both can be heard frequently in this recording.

The recording begins with a song by Puerto Rican singer Kany García followed by the program "De Buena Tinta" (literally "of good ink" but an idiomatic expression meaning "on good authority") beginning at 20:00 UTC. This is a news program for residents of Havana including events taking place, weather, and sports. At 20:30 UTC, there is the program "La Novela" (The Novel) with an instalment of "La Flor de los Sueños" (The Flower of Dreams). Next is "Un Amigo Cincero" (A Sincere Friend), a brief program on the literature of José Martí. The program "Por La Habana" (Around Havana) begins at 21:00 UTC. This program is mostly music with Cuban jazz, blues, and funk. Between every few musical items is a discussion of indigenous languages in Latin America and elsewhere and their impact on music. At 22:30 UTC, the program "Para Luego es Tarde" (meaning colloquially "no time like the present") begins. This edition features a discussion about corn (maize), its history and how it is grown, harvested, marketed, prepared for food and other uses. Midway through the program there is a musical interlude with a short discussion about the Bee Gees with excerpts of several of their songs. During some of the programs in the recording, mention is made of the 503rd anniversary of the founding of Havana on 16 November 1519. Public service announcements about health and other matters are also present throughout the recording.
