Radio Taiwan International (RTI) on 7129,88 kHz

Ron Howard from Monterey, Asilomar Beach, California, USA reported to the IARU Region 1 Monitoring System the activity of Radio Taiwan International (RTI) with a powerful signal on 7129.88v, RTI, 1245 UTC, August 9, 2009 broadcasting in Bahasa Indonesian language with a program about Mata Hari; 1257 ID.

Radio Taiwan were on frequency from 1400 to 1800, broadcasting  in Chinese, which was effectively jammed by CNR-1 echo programming. Slight drifting was noted; best in LSB to get away  from the het generated with Sarawak FM being on 7130.50. Sarawak is totally lost to the RTI powerhouse!

Ron originally observed Sarawak FM abandoning 7130.0 kHz back on March 31, 2009 and came back on July 19, this time on a frequency of 7130.50 kHz.
