Voice of Korea (North) in English: June 4, 2017

Voice of Korea (North) broadcasting in English, June 4, 2017, at 1330 GMT on shortwave frequency of 13760 kHz (transmitter power of 200 kW, transmitter location: Kujang, North Korea). Recording made in Europe using SONY ICF SW 77 receiver and 33m lonwire antenna with baloon hung around 4-5 meters above the earth level.
As heared clearly in this recording, the transmitter runs initially with no audio, carrier only, but soon an audio feed is switched on and off, indicating that usually audible annoying hum is not due to a faulty transmitter, but rather because of some problem with audio feed.
