Voice of Vietnam recorded in London, UK on September 2, 2015 at 2030 UTC on the frequency of 9730 kHz using a Lowe HF-150 radio with the Lowe PR-150 preselector, DX Engineering NCC-1 phaser connected to two Wellbrook ALA1530S+ antennas (positioned indoors) to mitigate severe local man-made interference. This was a special broadcast dedicated to the 70th anniversary of Vietnam's declaration of independence.
The transmitter has a power rating of 100 kW and is located in Hanoi, Vietnam. Due to a malfunctioning of the recorder, there were several short gaps in the recording, which were filled in using an earlier (weaker) recording of same broadcast on 7280 kHz at 1900 UTC on the same day. The gaps were as follows:
01:30.619s - 6.415 seconds long
02:08.512s - 1.486 seconds long
02:44.216s - 3.366 seconds long
03:02.060s - 28.847 seconds long
