The really anomalous thing is the big 60/120Hz pulse at 0:37, click above. I was shooting out front of the house, and I reviewed the whole video while standing there, and found the 120Hz. WTF!? It had to be EM, there'd been no audio like that while filming. Was I painted by a uWave beam?
I'm right near airports, also a couple miles north of a Boeing mil black project building. But radar is clicks, not 120Hz. And it sounds like changing PWM during the pulse.
That was my first thought ...while standing out there checking the video a few seconds after shooting. But it was confusing me, because there was no motorbike. I'd been trying to shoot without car noise, so I was facing the road, and (mostly) waiting for any vehicles to pass. When cars pass you can hear the loud wind/wheels hiss in this vid. I noticed that weird hum even in my tiny camera speaker. Later I checked for it indoors, and still there.
I suppose I should check the frequency. If not right at 60/120Hz, and has doppler of moving vehicle, then it's much more likely to be a bike(etc.) that I'd not noticed down the road, and then my brain had edited out while I was talking. Finally, there's a power line about 20ft up on the other side of the street. Huge current surge? The usual b-field from that thing is so strong that any small pickup coil in my house will detect it, and for sensitive work I have to go to the back of the kitchen, over 100ft distant.
Lol, editing cut.
