BACKWARDS MUSIC OR "THE WHALES" (XM)
Thank you for the confirmation. Like i said i never heard anything like this.
That sounds like something from Transformers! Hey Juniorswl here from irc!
This is an artifact from a type of military comm. I say artifact because it contains no intelligence-at least on the soundbyte I heard.The odd thing is that it runs most of the time even when there are voice comms present. I wish I could remember specifics but one of the writers for Monitoring Times did a great piece on it several years ago. I have been hearing these signals since the 1990s and could tell when there were voices present. Not sure, but this may be what is called pseudo noise. Wish I could help more! VY 73s de Hans-WA1UFO
