Paul Turkk:
I caught 2 screen shots of what I'm told looks like a HAARP signal.
This was at 0155. I saw this twice. Can not remember for sure how it sounded.
There were some operators trying to make odd waterfalls around the same time.
Location is SW Michigan, Berrian Cty.
I need to get in the habit of recording at least the audio when i'm tuning.

Josh:
Yep, or someone retransmitting HAARP audio. Wonder what heater was in operation.

Token:
Not sure I would call it someone retransmitting HAARP, however it is certainly one of many types of transmissions HAARP is known for, a linear audio tone sweep.  Anyone could achieve the same thing using an AM transmitter and an audio tone generator with a sawtooth capability.  It might be accidental that it looks like HAARP, or someone might have been trying to simulate HAARP.

With that said, it is pretty wide audio.

I don't see any indication from typical sources that HAARP is, or was, on that date, active.  They certainly did not show up while I was looking on any of their common frequencies and I have not heard any reports of activities on those freqs.  Arecibo is gone, and unlikely to ever return, if it does it will be years before it is active again.  It obviously could have been a different experimenter, but typically those kinds of things go on for hours at a time, and days in a row.

Since it only happened a couple of times I would guess it was not someone trying to look like HAARP, but just someone testing audio / transmitter.

T!
