Big S9+7 carrier with some trace/intermittent audio here from time to time.

First noted 0132, last off around 0147z. 0152z

Also been noting similar sometimes concurrent testing on 6930AM around S8 here 0140-0142z

Noted here as well on the SDR recording. Heard some CW mix in with audio.

The transmissions were very 6 minutes starting on exactly the minute (or within a second or two) and ran for 90 seconds. Starting at 0115z, then 0121z, etc until the last transmission at 0227z.

No idea what this is. I was first going to say pescadores, but it doesn't seem to fit their MO. Nor the average pirate. There is a lot of oddball gov/quasi-gov stuff in the 69xx range, so I am leaning towards that.

Any other ideas?

HAARP.

The 6900 kHz carrier is associated with the 100 kHz wide FMCW HAARP transmission on 7700 kHz.  The last few nights I have noted this 800 kHz offset carrier with the HAARP FMCW.  Note that the carrier happens twice as often as the FMCW waveform.

After HAARP vacated the 7700 / 6900 kHz pair it moved the FMCW to 6900 kHz and the carrier was on 6100 kHz.
