Unid 9060 DIGI
« on: February 14, 2022, 2355 UTC »
9060 USB 23:30 UTC Feb 14 2022 S5 Not sure I've ever heard this before. Haven't found anything, I think, on the Sigidwiki. Appears to be 4k wide with 4 channels? Not local interference as it fades with the propagation. Been running steady for about 30 minutes since I found it still going. Hear on KFS SE KiwiSDR, Half Moon Bay, CA, USA so west coast signal maybe. Not heard on any European SDR. Asian/Pacific Rim or Russian signal origin?

This is what it looked like:

This signal is what I call the Multi-FSK Oddity in my logs.  It has been discussed a few times on this forum, and it has a few different modes.  The mode you have posted is the most common I have seen in recent months.  I have seen it in everything form 2 kHz width to 10 kHz width, and rates from 10 Hz to over 100 Hz.  Various frequencies from below 7000 kHz to above 20000 kHz.

This signal has been attributed to HFT (High Frequency Trading) sources, and that is a very good probability, but to the best of my knowledge that has yet to be confirmed.

The primary sources I see are in the US, a few different locations.  There are also some HFT signals observed and sourced in Europe, but I don't think I have seen this specific signal from a source there.
