Radio Juliaca is the oldest radio station in town, and that's why they call themselves La Decana. The announcement I heard was like "... 1300 kilohertz en Amplitud Modulada y 90.9 en Frequencia Modulada - Radio Juliaca, La Decana". Both their web site www.radiojuliaca.com.pe and the email I received say the AM frequency is 1290 kHz, but still they announce 1300 kHz.
Juliaca is at 2823 meters above sea level, and has a population of approximately 300.000.
In the same moment that night CP107 Radio Yaguarí was heard with a great signal on 1440 kHz.
