    I do know that her autistic daughter jumps when fireworks go off at an event, but fireworks don't bother our friend at all. That's just being startled. Her house like any other house is mostly likely surrounded in RF. I on the other hand have VHF, UHF and HF but don't Tx that much and obviously never when they come to visit. All they have (to the best of my knowledge) are cell phones and no complaints there.

    There are smart meters that only transmit a few times a day. What type of meter is it? A picture of the nameplate would help.

    I have no idea but they only live a few blocks from us so one would ASSUME ours is the same. I'll check ours out later and post it here

    Aluminum FOIL is inadequate shielding from mind control radiations.
    The test subject appears to have an extrmemely high sensitivity to RFI, the best defense is FERRITE shilding. Contact Amidon, or Palomar Engineers, see if they are able to fashion a FERRITE Yarmulke, I recommend MIX 75 optimized for most common mind control band: 100Kc to 10 Mc

    This one
    This one transmits more than just a few times a day - it transmits a number of times in a 5 minute period.

    The 'big pulse' is the meter about 10 feet away, the smaller pulses are the neighbor's meters:

    The video was unavailable. Yes there are electric meters that transmit 5 minute intervals. We use those for Conservation Voltage Regulation (CVR). They are a small percentage of the network. For energy, 5 minutes is a bit much. You can collect 5 minute interval data, but only transmit once an hour. Usually 15 minute interval data transmitted hourly is becoming the norm. My meters transmit for 150 msec.

    Check it again - it was in the process of uploading ...

    Anytime I've checked my meter, it was always active, like seen in the video.

    Here's what 900 MHz looks like in the middle of Silicon Valley. This is with an indoor antenna.

    Is "Peak Hold" enabled - or is this just a 1 second snapshot?

    What kind of pulse responses do those big SDR spectrum displays have - can they catch a 2 or 5 millisescond RF pulse?

    And then we have the WF display - what kind of pulse response does it have?

    No peak hold. There is some averaging going on with the panadapter, but it's a very short snapshot.

    The sample rate to capture the entire band was 26 Msps, so theoretically the waterfall pulse response is 0.63 milliseconds (1/26000000 sps * 16384 fft size)
