Well, I never bothered looking up my own POCO's website for info, It's a small Cooperative and i didn't expect anything, I just did general google searches, but i think i found the answer now.
From a PDF info sheet on their website,
"Information from the meter is sent back to the coop over power line carrier in hourly increments."
That means I'm hearing all my neighbors meter transmissions also. Explains why some are some are much louder than others. Wonder if I can decode them??
Most of the info i read about generic AMI or AMR smart meters talked about 900Mhz wireless transmission.
I had 4 scenarios that might be causing it to begin with, Fault to earth in an underground feeder was the most plausible one that concerned me, but after seeing the waveform on the scope I assumed it was power line carrier.
Damn signal turns the touch light by my bed on every day.
