Title: UNID digital signal at (approximately) 11064 kHz
Post by: Strange Beacons on April 07, 2017, 1651 UTC

UNID digital signal at 11064 kHz: https://youtu.be/8QJw7nIiuTk

I noticed this signal to the left of the frequency where I was monitoring a Russian number station transmission (E07a). It appears to be some sort of MFSK signal, but I'm not sure which type.

UTC time and date noted in video.

The start of this UNID transmission (1530 UTC) can be seen at the beginning of this video and to the left of the frequency I was monitoring: https://youtu.be/0nuUBlfphyI

I'm not certain that I had this on the correct frequency intended for the transmission. But it is close enough that it would likely decode.

Interesting that it started at just about the same time as the voice traffic, and on a nearby but not interfering freq, maybe related.

Yes, if you watch the UTC time clock that is running at the top right of the E07a video, the UNID signal starts at exactly the same time as the number station does: https://youtu.be/0nuUBlfphyI

When it comes to these "secret spy signals," I don't believe in coincidence.
