Radio Sensacion, Peru


The following item is taken from Relampago DX by Takayuki Inoue Nozaki. It is placed here with permission.

It was in early June of 1986 that Radio Sensación, the third broadcaster established in Huancabamba, was first monitored by DX enthusiasts on the measured frequency of 6021.3 kHz in the 49 meter band. The station first poked through the ether, proclaiming itself as "Radio Sensación, la nueva generación en radio, la radio que saluda más y mejor". After having carried out its experimental transmissions for a couple of weeks, the station unexpectedly vanished from the airwaves. However, after a silence of about three months, the reappearance of Radio Sensación was noted on September 1, 1986. Broadcasting in the 49 meter international band, the initial operations had suffered from powerful international broadcasters especially in the local morning and evening. Regardless of the internationally defined broadcast band, Radio Sensación found a suitable channel free from interference, and eventually resumed transmissions on an odd frequency of 6791.6 kHz in the fixed service band. Although the station aimed at nominally operating on 6790 kHz, it was logged that the shortwave outlet drifted in the frequency range between 6791.4 kHz and 6791.8 kHz from September of 1986 through July of 1987. Afterward, the station slightly moved up to another variable frequency range between 6792.2 kHz and 6792.5 kHz, in which it remained from November of 1987 to January of 1988. At that time, the station started the morning broadcasts at 1100 (i.e. 0600 local time), which could be audible with fairly good signal in Japan. The early morning program "Panorama Agrícola" which provided a variety of Peruvian folklore with useful information for farm workers, was broadcast at 1100-1200, and then an agricultural program entitled "Por la Región Campesina" followed.

When Radio Sensación resumed its transmissions in the middle of October of 1988, the station switched over to 6895.2 kHz. The frequency change was made either to avoid interference from utility stations operating around the channel or probably because of another technical problem. The operating frequency was nominally announced on the air as "6890 kHz en la banda internacional de los 49 metros", but it was monitored between 6895.2 kHz and 6895.4 kHz, approximately 5 kHz higher than the nominal frequency. The station has settled down on the frequency range for roughly eight years with some short intermissions. It was in late October of 1996 that Radio Sensación was last traced on shortwave.

Subsequently in late December of 1996, a new station commenced broadcasting on the same general frequency range on which Radio Sensación had formerly transmitted from October of 1988 to October of 1996. Obviously the station carried its signal utilizing the same transmitter of Radio Sensación. The station identified itself as Radio San Miguel, transmitting from San Miguel de El Faique, one of the eight districts of the Province of Huancabamba, located about 55 kilometers from the capital of the province. Radio Sensación apparently ended its shortwave broadcasts by selling the transmitting equipment to another broadcaster. However, it was not known that the station had absolutely left the transmissions, or continued broadcasting on medium wave or FM.

Two years later, the station began the second era of broadcasts on shortwave, renaming itself as Radio Super Sensación and also Radio Super Nueva Sensación. The experimental broadcasts were carried out in early September of 1998. The station announced it was nominally operating on 6620 kHz shortwave and 99.8 MHz FM. However, the shortwave outlet was virtually tuned on the measured frequency of 6618.2 kHz, and then slightly drifted down to a variable frequency range between 6617.1 kHz and 6617.8 kHz, in which it settled down until late January of 1999. Radio Super Sensación changed its frequency in April of 1999, and moved up to 6675.5 kHz. Subsequently the shortwave outlet remained in the variable frequency between 6674.0 kHz and 6674.5 kHz. The remarkable point is that Radio Super Sensación transmitted in the similar frequency range, where Radio Ondas del Río Marañón had been on the air from September of 1997 to June of 1998, and under the name of Radio Impacto from late October to late November of 1998. However, it does not state definitely that Radio Super Sensación broadcast with the transmitter which had been formerly used by Radio Ondas del Río Marañón, because it could be just a casual coincidence. This question needs to be solved by future research on the broadcasting scene in Peru.

On December 25, 1994, I went to visit Radio Sensación, located at Avenida Ramón Castilla No. 331 in Huancabamba. It was extremely easy to find the station from a distance, because it was in a two-story house with red tiles and walls prominently decorated by vivid sky-blue with paintings of the station name "Radio" in white edging by black and "Sensación" in red, and an antenna tower. On the rooftop, antenna cables suspended by two small poles also could be seen. Entering inside the operating cabin, a disc jockey - operator could be seen conducting a music program and playing cumbia. I explained to the disc jockey that I came from Japan and had heard Radio Sensación on shortwave since many years ago. The disc jockey who I met at the station was Asunción Carrasco Cruz, the oldest son of the station owner. He informed me that the owner had been on a business trip since several months ago, and the station was operated and managed by his family at that time. He was surprised by the unexpected visit of a Japanese listener. As he had already learned by letters from abroad that the station had been audible in different countries of Europe, the United States, and Japan, he gave me a hearty welcome for my visit, and showed me around the facilities. The facilities were composed of a reception desk, a studio, a small music library, and a narrow room where the transmitting unit was installed. The studio was surrounded by plywood partition wall, and was equipped with a "FRANVEL" brand console mixer (six channel), a "Technics" HX-PRO model double cassette deck, a "SONY" DCFM-D1 model radio cassette, an "AMPEX" equalizer, a turntable, and a microphone. The music library had about 500 volumes, including 45s and LP records, and cassette tapes, divided into categories by song type: folklore, chicha, salsa, ranchera, pasillo, Latin American modern pops and oldies. Behind the studio, there was a transmitter of "FRANVEL" brand which could produce an effective output of 0.5 kW as maximum power. It was fed into a 1/2 wave dipole antenna on the roof (15 meters high above the ground).

On March 19, 1986, "Radio Sensación Empresa Individual de Responsabilidad Limitada" was inaugurated by Justo Emilio Carrasco Moreno. Radio Sensación commenced the test transmissions on the nominal frequency of 6020 kHz with a "FRANVEL" brand transmitter of 0.25 kW. The station initially established in the 49 meter band, though it was awfully interfered by several international broadcasters on a nearby channel. While illegal broadcasting activity in Peru greatly increased on the shortwave bands in the 1980's, many stations seek out vacant frequencies outside the broadcasting band to be able to broadcast programming without interference. After researching the shortwave bands for a couple of months, Radio Sensación found a practical location on a vicinity of 6790 kHz. Initially the station broadcast with a staff of five persons, at 1100-0100 for 14 hours from Monday to Saturday, and 1200-2400 for 12 hours on Sunday, providing newscasts, cultural programs, information, entertainment, messages, and typical music of the region.

In October of 1988, Radio Sensación purchased another "FRANVEL" brand transmitter with 0.5 kW, in order to enlarge its coverage. The station came into the airwaves on the nominal frequency of 6890 kHz. Afterward, the first transmitter which lastly emitted its signal in the frequency range between 6792.2 kHz and 6792.5 kHz, was returned to the maker in Trujillo, Department of La Libertad.

When I visited Radio Sensación, the station had slightly reduced its transmissions. It broadcast at 1300-2400 for 11 hours from Monday to Friday with the following programs: 1300-1400 "Amistad Musical", 1400-1500 "Festival Tropical", 1500-1600 "Música Romántica", 1600-1700 "Música Juvenil", 1700-1800 "Voz y Sentimiento de los Campesinos Sondreños", 1800-1900 "La Hora Cultural", 1900-2000 "Gerenración Juvenil", 2000-2100 "Canto Andino", 2100-2200 "Aires Huaringueños", 2200-2300 "Voz Campesina", 2300-0000 "Gerenración y Jarana". On Saturday, the same weekday's programs were scheduled except for 1700-1900 "Acuarelas Huancabambinas". On Sunday, it broadcast at 1300-2300 for 10 hours, reading messages and congratulations over the air between music and music.
