  Thinking that if these signals are from Korea, then a KiwiSDR in Japan should receive the same signals and possibly stronger. So here is an image from http://travelx.org:8073/ . And sure enough, there they are. Propagation tends to show this signal to http://ka7u.no-ip.org:8073 around 0800 UTC.

  Hi,

  
  

  Only a few countries have an Amateur allocation above 3.8MHz, mostly it's used for broadcast and utility stations.
  

  
  

  So it's almost certain to be Voice / Echo of Hope or Voice of Unification plus jamming.

  
  

  They tend to move around the same segments of the broadcast bands within a few 10's of KHz in order to try and avoid jamming.

  
  

  Regards,
