    I've seen people put a simple AM radio in their microwave and it quits picking up the local country rock station. Again.... it works at a specific frequency.

    The strength of the signal is another factor. An EMP that originates 20-30 miles right above you will have more of an effect than an identical source several hundred miles away.
    I have also read that proximity is not a reliable indicator of intensity either, and that the most damage would be delivered at an angle from the detonation site. The more I read the more theory resembles voodoo.

    Long story short: There's scant reliable evidence due to lack of methodical testing. The only real way to get down to brass tacks is to start setting off EMPs at various frequencies, intensities, heights and angles from a test location.

    Of course, that's going to go over about as well as Beto taking our ARs and AKs.

    I try not to make plans much. The word 'premeditated' would get tossed around in court.

    Not sure if this has been addressed as yet but......EMP's aren't always man-made. The sun can also produce an EMP if there's enough flare activity. Then there's the # of grids in the US that can be effected. We have 3 grid systems. East, West (I think the Mississippi River is the divider)…..then there's Texas (ERCOT). Not sure how they got their own but there it is.



    So if we are hit with an EMP, regardless of it's source, and only a small fraction of the population have successfully protected their electronics...….who ya gonna call??

    An EMP will cover a frequency range from maybe a 100 MHz to 100 GHz or so. The protection needed should be as high as you can afford to do.
    That's why I use the triple foil wrap with insulating plastic between each layer and then everything goes into sealed, metal garbage can sealed
    with foil tape. Inspect the can. I found a can with hollow, riveted handles that had to be sealed with tape. I opted to solder the rivets closed.
    I removed the handles on the top of the garbage can lid and soldered the holes closed. That way I can stack the cans one atop another to save
    space.

    As far as the sun, A CME can create a Magnetic storm. According to Dr. Bradley, as long as the elctronic device is not plugged into and outlet, it
    will be fine.

    One thing I was not originally aware of. Some lithium batterys have internal regulators to prevent over charging. This could be damaged by an
    EMP, so I now triple wrap my lithium batteries with aluminum foil and plastic and store them in a good sized candy tin with full cover. I used a
    wire brush on a bench grinder to remove the paint for a metal to metal connection and seal it with foil tape so I can take them out and charge
    and run them couple of times a year.
    I really want one of these!Hidden Content
