Jamming modulation:
  (a) Programs of China National Radio in non-distorted AM mode for 
      long distance high power (100-500 kW) sky-wave operation. 
  (b) Programs of China National Radio in Narrow FM - mostly for local
      (ground-wave) operation.

- Chinese musical jamming is targeted at Radio Free Asia, Voice of 
  America, BBC, Deutsche Welle, Falun Dafa and other stations.

  in Europe at the same time. The frequency that propagated best in
  Europe during July 2002 was 15680 kHz: daily from 1400 to 2200 UTC. 

  You may hear 1, 2 or more jamming transmitters on the same frequency
