In the last few days, several technical problems have been reported that cause the air output of some AM stations operating from the AMBA area (Area Múltiple Buenos Aires). For example, Eco Radio AM 1220 (1220 KHz) is not being reported active, the only station that owns its transmitting antenna in the territory of the Autonomous City of Buenos Aires.
LR9 Radio Perfil (1190 KHz) is also not being heard, due to adjustments to its Transmitter Plant located on the Campus of the National University of Lomas de Zamora.
Also not heard for a few days Radio La Más Santiagueña (1160 KHz) at Gregorio de Laferrere, Partido de La Matanza; and Radio Imagen (1310 KHz) at Castelar, Partido de Moron. Also Radio Creativa (1230 kHz), with radiating system located in Valentín Alsina, Partido de Lanús is not received; as well as the evangelical religious station Radio Zorobabel (1540 KHz) from Monte Grande, Partido de Esteban Echeverría.
