Very strong signal, but unclean and impossible to stabilize

stations with similar problems.
Listed on 6188v kHz, where it has been off the air. Announcing

Oriente, Yurimaguas, one of the most widely heard Peruvian
shortwaver, established on March 13, 1966, at Calle Comercio
No.17, in front of the main square, Plaza de Armas.
The first transmission was made from the transmitting plant
at Kilómetro 4 on the Yurimaguas-Tarapoto highway,
operating on 1420 kHz medium wave under callsign OAX8Z.
The creation of this pioneer broadcasting society in
Yurimaguas was performed thanks to the initiative of two brothers:
Jorge Chu Ruiz and Emilio Alberto Chu Ruiz, with a clear commercial
format, but also including participation from the different
"Radio Oriente S.A." had the following initial stockholders:
Max Benzaquen, Juan Antonio Yap, Ricardo Arevalo Flores, and
On February 15, 1977, Monseñor Miguel Irizar
Campos of the Vicar Apostolic of Yurimaguas acquired the majority
of the stocks and authorities of "Radio Oriente S.A.".
On December 27, 1977, it was transformed into a Limited Responsibility
During 1978 the station was inactive because the transmitting
plant was re-installed on Avenida de Las Américas and
the studios were also re-located at Calle Sargento Lores No.207
in downtown Yurimaguas.
As the new location proved to be inconvenient, the studios
were moved again to Calle Progreso No.112, where they maintain
their definitive address until now.
On January 1, 1980, Radio Oriente began the shortwave
operation on 3285 kHz in the 90 meter tropical band, licensed
under callsign OAX8I.
The shortwave broadcast was added in order to cover efficiently
the whole Department of Loreto and also the Department of
The station had operated on 3285 kHz during the experimental
transmission for about one year, equipping with a "Petrick"
brand transmitter of 1 kW output, but as result, they learned
two serious matters.
First, before sunrise and after sunset it was noticeably interfered
from an Ecuadorian broadcaster, Radiodifusora Cultural "La
Voz del Napo" on 3280 kHz.
Secondly, the 90 meter band transmission could not get enough
coverage for the audience living in the remotest villages.
To solve these technical problems, the shortwave outlet changed
the frequency from 3285 kHz to 6190 kHz at the beginning of
1981. Since then, Radio Oriente became one of the few regional
shortwavers, officially authorized to broadcast in the 49
meter international band.
In 1988, the ownership was wholly transferred to the
Vicar Apostolic of Yurimaguas for the purpose of cultural
orientation, education and Christianity promotion.
Naturally, Radio Oriente has continued to play an important
role as a medium of social communications, broadcasting news,
information, sports, entertainment, music, and social service,
for both the rural and urban population. Therefore, the station
has identified itself as "la onda popular que mejor se escucha"
(the people's best heard station) since the foundation.
