[IRCA] 621-Pyongyang BS/ VoK-- Audio Situation Becoming Critical

[Gary DeBock <d1028gary@xxxxxxxxxxx>]

A few months back there was a discussion on the list about the transmitted audio from the 621-Pyongyang BS/ Voice of Korea station in Chongjin, N. Korea-- specifically, whether there was audio hum on the frequency from a bad transmitter, or whether the bad audio was caused by a drifting frequency.

     Yesterday morning a recording was made of 621-Pyongyang BS mixing with 621-China (Heilongjiang) at the 1500 TOH, with the two sets of pips loudly overlapping at the 39 second point  https://dreamcrafts.box.com/s/612kbk25hqqlxh1r4qfzaxzeuuwktbeo

The throbbing hum from Chongjin's transmitter is pretty obvious, distorting not only the Pyongyang BS audio but also covering Heilongjiang's clean signal. The overlapping time pips from the two are in the same bizarre league as the "Cuckoo Clock" overlapping pips from 918-Shandong and RNZ at 1700 UTC in the Cook Islands.
