Hello!
Around 4PM UTC, Feb 27th I picked up this group of tones of various levels traveling up and down around 9mhz for a couple minutes.
The sound it makes it what lead me to believe it's a test of some sort. Same tones that sometimes are solid, and sometimes vary back a fourth a couple hertz. Looked like interference at first but it was isolated to just this band. The first thing I did was check other Kiwi SDRs around my location. The signal wasn't picked up very far away from my location in Rhode Island. You can see In the video what SDRs picked it up. it was easily being heard in New Hampshire and Montreal Canada. Everywhere else.. nothing. tough cause not everyone's SDR has a good or working antenna.
All of a sudden it disappears, never to be heard again. Could not get a match with any of my known sources.
This is when I first caught it, notice the tones are solid, then switches to a back and fourth movement.

The it stays dynamic throughout the course. while traveling up and down in frequency.

Video:
(please excuse the random cut outs, I am running SDR++ on a radio way back in my back yard, over wifi, that's then over VPN thats running over my tethered cell phone while i'm at work with low signal, sorry!)
If interested, I can share a link to the IQ file I recorded.
